lipo charger Buyer’s Guide

If you keep the before points in mind, you can easily go out to the market and buy lipo charger, right? No!

Cur​​​​rent​

Another thing that you have to look out for is the charging current. Batteries have a max charge rate which is usually at 2c. However, you may want to check the charge current to see if the charger has enough capacity to take your batteries.

Power Su​​​​pply​

The last thing that you have to take note of is the power output. LiPo batteries all have power output levels indicated in Watts. So when you buy your charger, you have to make sure that the power output of your charger matches the power output levels of your battery.

The usual standard output level of most batteries is approximately 50 watts, so your charger should also have a power output of that level too.

P​​​​rice​

Now that we’ve gone through the technical aspects to look out for, one more thing to watch out for is price. You really have to set a budget for your charger and stick to it. However, I would recommend that you buy the brand that’s a little more well-known even if it does cost more.

Since this is an electrical appliance, you may want to stay away from cheap ones because they might be of low quality and possibly cause fires or explosions.

The Quick Answer

ISDT SC-608

Its also worth giving an honourable mention to the IDST 60charger as it does stand out as an impressive charger. It has a very nice design with a high resolution, ultra bright 2.inch IPS display to make this charger stand out from the competition. On paper it seems like an excellent charger. It has a massive 150W, can charge most batteries (LiPo, LiHV, LiFe, and Li-Ion) from 1-Cells so it does everything you need. So you could argue that this is even better than the Skyrc S60.

The only reason why I do not suggest this charger to most people is that it does not include a power supply. In general this is not necessarily a big deal, but due to the high power of the IDST 608, you need to get a 150W power supply which is not cheap. IDST make an official power supply (CP1602Power Adapter) for this, but it costs the same as the charger itself, doubling the overall price for this charger. Because of this extra cost means this charger is not as good of a deal as it first seems.

Keep An Eye On Your Battery!

Never charge your battery unattended – from time to time check to see if your battery is getting warm to the touch or starts to sewll, if so stop charging immediately and contact an expert immediately (like someone on dronetrest) before using the battery again.

Always charge your battery at 1C or less – many chargers allow you to set a charging rate, although most batteries can support up to 5C charge rates (which makes charging your battery much faster). Its always best to charge at 1C or less as this means the chemicals inside your battery will gain energy slower which keeps them more stable and ultimately means your battery will have a much longer life in terms of charge/discharge cycles.

Ensure the number of cells and battery type are set correctly on your charger to match the cell count in your battery. – this is only applicable for more advanced chargers.

Battery-charger.jpg

Some chargers like the one included with the DJI Phantom many not appear to be a balance charger, but that is because the phantom battery actually has a built in battery monitor and balancer built into it.

Charging current

Most batteries specificy a maximum charge rate as 1C, 2C etc… however most chargers you specifiy the charge rate in Amps, so sometimes there is confusion between these two values. To convert your battery C charge rate to Amps you simply need to multiply the battery capacity by the C rating. So lets say we have a 2200mAh battery with a charge rate of 2C. So the maximum current we can charge this battery at is 2.2Ah x = 4.4A. Similarly lets say we want to charge a 5100mAh battery at 1C, the max current we will need to set on our charger is 5.1Ah x = 5.1A. The maximum current you can for your charger depends on the power output it is cable of as described in the next section.

Power Output

All batteries have a certain power output level, defined in Watts, typically around 50W. This number represents how much power the charger can provide to your battery, ultimately the larger this is, the faster it can charge your battery. Watts are the product of current and voltage, so if you keep current constant (say at the recommended 1C value) you will use more power with higher voltage (bigger cell count) batteries. So having more power available it better. Lets look an example, if we want to charge a 3S 2200mAh battery at 1C we will need to use 12.6V x 2.2A = 27.72W. If we want to charge a 3S 5100mAh battery at 1C we will use 12.6V x 5.1A = 64.26W which is actually a little over the standard power rating for chargers. So we an only charge our 5100mAh battery at 50W/12.6V = 3.6A assuming we have a 50W charger.

Power Supply

Some batteries include a built in power supply so you dont need to worry about this. But if your battery does not include a power supply you will need to make sure that the one you buy will match your charger in terms of specifications and also the connector is the same. At Unmanned Tech we have the option to add a compatible power supply on most of our chargers.

However the most important thing is to ensure that the power supply has the correct power (Watts). So if using a 50W charger, you will need to make sure your power supply will be able to provide at least 50W of power to the charger, however getting something a little over is best such as a 60W power supply.

The process of charging a battery

Although each brand of charger might have different features, I will discuss the main ones that are shared with all Lipo chargers so you can have a basic idea of how to use them. For full details its best to read the documentation included with your charger. Some simple chargers just require you to connect them and it will start charging automatically.

Fast Charge

Some chargers have a fast charge feature which in my opinion is more of a gimmick than a useful feature. Fast charge allows you to save abit of time when charging your battery as it will skip the balancing step. In fast charge mode the charger will only look at the overall voltage of your battery and will stop slightly below the maximum charge for safety reasons (as the battery might not of been perfectly balanced at the start of the charge). This is only usefull if you want to get flying int he air, but in reality this does not save much time over a proper balance charge so to get the most life out of your batteries its best to always use the balance charge.

Battery Storage

Another useful feature that some chargers have is the Lipo storage mode. If you remember from your Lipo battery guide, its best to store your battery at about 40% to 50% charge. So the storage mode on your charger will automatically charge/discharge your lipo to this range in each cell so you can safely store your battery when you are not going to flying for a while.

Digital Multimeter

This is a very cheap battery pack charger from Holy Stone that will charge five packs at the same time. It needs power from USB, which can be from a power bank, computer, or wall charger. The best results will come from a wall charger with enough amps to charge all five batteries at the full 500 mAh rate.

It’s dirt cheap, going for anything between ten and twenty five bucks. It has all the safety stuff you need and, combined with a LiPo safe and wall charger, should keep you in the air for much longer.

People do complain that, although it works, it feels very cheap. It’s also pretty tricky to unplug the batteries without either long fingernails or a small pair of pliers. You don’t want to yank on the wires, that’s for sure.

Venom Pro 2

I’ve owned Venom charging products before and they’ve always been a pretty cost-effective way to get your various batteries charged. The interface is simple and this model, the Venom Pro 2, has a perfectly adequate amps on tap. For most multirotor fliers it’s unlikely that you’ll have batteries that come even close to needing that. You can charge a variety of battery types, but of course we mostly care about LiPos. The Venom can handle LiPo batteries with as many as six cells.

The most attractive thing about the Venom though, is its price. At about sixty bucks it’s half as expensive as similarly-specified chargers, and for someone starting out that only has basic charging needs it’s a good place to start.

It has the thermal safety alarm that you really want in a charger like this and will automatically shut off if it feels something is wrong while charging.

It has features that are generally considered high-end, such as internal resistance measurement and different battery profiles for discharging that you can save, and it comes with the most popular lead types. If you can’t spring for a more expensive model you could do a lot worse than the Venom.

There have been some reports of build-quality issues, though, so don’t do things like constantly plugging and unplugging the AC cord. It’s probably best to use it as a bench unit rather than a field unit.

Welcome!

Welcome to our website – we’re glad you stopped by! If you arrived here from a search engine or a link from a forum, we’d like to invite you to take a look around the rest of our site after you learn all about LiPo batteries. At the end of the article, we’ll have some links to other articles and reviews you may find interesting. But above all, please share this guide with anyone you know that needs help with their LiPo batteries. The more everyone knows, the safer the hobby can become – and that’s good news for everyone.

Foreword

Whenever you read those news headline of someone losing their house to a LiPo fire, it is always because of some sort of charging mishap. Lithium Polymer batteries are at their most volatile when they are being charged, and one little slip up in the process can result in disaster. This article focuses on the how to charge LiPo batteries safely, with an emphasis of where things can go wrong and how you can prevent it.

Charging Process

LiPo batteries charge differently from pretty much every other battery on the market. The charging cycle starts with a constant voltage being applied across the battery terminals that is slightly higher than the voltage the battery is currently resting at. This causes a current to flow through the battery, beginning the charging process. This current must be regulated by the charger to not over-saturate the battery with charge. Once the battery is reaches a set voltage, the current flow is slowed and eventually stop. LiPo batteries can never be “trickle charged” and do not have a safe saturation point like car batteries where they will no longer accept charge. If you overcharge a LiPo battery, it will eventually explode – catastrophically.

This is the most important thing to keep in mind when charging lithium batteries – if you attempt to overcharge them at any time – they will accept the charge, slowly grow in size, and eventually explode in a giant fireball. It is also the big difference between LiPo batteries and other chemistries. If you plug a LiPo battery into a car battery charger or a NiMH or NiCd charger, it will very likely explode. You must get a LiPo charger to charge a LiPo battery.

Caution!

Most LiPo battery chargers are able to charge many different battery types. This is a cool feature, but if you use it, make 100% sure you never charge your LiPo battery with the charger in a non-LiPo mode. This is the surest way to cause failure and a fire.

If you started in the hobby with a toy micro quadcopter like a Hubsan or a Syma, you received the most basic type of LiPo batter charger as part of the package. These chargers plug into the wall and the battery just docks into them, charging automatically. Unfortunately, as you progress in the hobby to more powerful aircraft, things will not be so simple. A lot of this is because of the concept of cell balancing.

Charging Habits

Sometimes, you may want to charge your batteries using the “normal” charge mode – which is active when “CHARGE” is shown on the charger’s screen. When you charge using this mode, you need to be aware that you will be losing all of the safety measures built into the charger to prevent individual cells from being overcharged.

This can be safe if you are extra careful. You should purchase a cell monitor and verify your battery has no cell which measures a voltage of.2V greater than another cell. You should also be extra careful about selecting the correct cell count when charging.

Parallel Charging

A paraboard is a convenient way to charge many batteries at once, if your charger is up for it. It does require special precautions, however.

When you want to charge many batteries as quickly as possible, the best solution is parallel charging. While we won’t instruct you on how this can be done in this article, we will discuss some safety concerns with parallel charging.

First of all, make sure your parallel charging board has a built in short circuit protection fuse. Some more expensive boards also have fuses for each battery on the board. These will prevent situations where batteries are accidentally, rapidly charged by other batteries plugged into the board with substantially different charge levels. We use this paraboard an can recommend it, but you may want to opt for more safety options.

Next, you need to make sure the batteries you plug into the paraboard are all of similar charge levels. If you stop flying a battery pack partway through your normal flight time, make sure that battery is marked so you do not plug it in with the rest of the batteries. If you do not use a battery and it is left fully charged, that battery should also be marked. Check out vesp’s article on battery tags for some interesting ideas on how to do that. When in doubt, you should get out your cell balance checker and verify.

If you use batteries with difference cell counts, you need to make absolutely, 100% sure that you never plug the different batteries into the paraboard concurrently.

Stay Close

The first line of defense in your charging set-up is putting it somewhere where you can watch it. This is especially important if you charge your batteries indoors. Never leave your house unattended while a battery is charging. If the area where you are charging a battery is in any way flammable – you should not even leave the room. Either way, make sure the room you are charging in has a fire alarm.

Battery Containers

Putting your batteries inside of a fireproof container while they are charging is the next logical step to prevent or reduce damage in the case of a mishap. Whatever container you decide to use – make sure that you never seal batteries inside of an airtight container – when LiPo batteries “go-off” they release pressure and heat – perhaps enough to make a bomb if sealed up.

LiPo Bags

Some manufacturers have come out with firesafe bags for charging batteries in. When these bags work, they contain any flames caused by an explosion so that your house doesn’t get lit on fire. Be aware, though, that these bags are not regulated and there are many which can be purchased from otherwise reputable vendors which will not stop a flame at all. We are planning on doing a detailed comparison test on these bags in the future to find out which ones work and which ones do not. Honestly I would have a tough time trusting any bag unless you have proof that it works.

Batteries

Schumacher’s CR-charge ‘n Ride is well known as a universal charger for the battery used to power ride-on toys. This charger can work with any devices such as Razor, Power Wheels and Schumacher that use 2volt batteries. This charger is almost times faster in charging and another interesting part is that by charging with it, you will be able to ride longer.

The batteries used in drones are mostly of Lithium Polymer (LiPo) type. These batteries are very light-weight, have an excellent energy density, very high discharge rates are possible and have low self-discharge rate. LiPo batteries are best suited for drones due to high current requirements of UAVs, in particular for racing drones.  Although, LiPo batteries do not require much maintenance but still need some care and precautions. The most important thing to keep in mind is that drone batteries are sensitive to low voltage when discharging and sensitive to a high voltage when charging. To avoid both of these, never drain your battery below 80% of its rated voltage and never use a cheap battery charger. If you keep flying your drone at low voltage, your flight time might increase, but the maximum number of recharge cycles (Life) of your drone battery would decrease.

C-Rate of a LiPo Battery

Without going into the physics of this, I try to explain this with an example. If a battery having the energy of 5000 mAh discharges at 1C (C-rate of 1), it will provide 5000 mA for one hour. If the same battery is operating at 2C, it will provide 10000 mA of current for 0.hr. Also, if this battery is operating at 0.5C, it would deliver 2500 mA of current for hours.  Some quadcopters have high amperage requirement, and the battery should be able to cope with this. The discharge rate is expressed as multiples of C, such as 2C and 3C, etc.

How to Calculate the Endurance of a Battery

One of the leading indicators of the health of a LiPo battery is its shape. The battery should feel stable and firm in hands. There are few things you must inspect every time before you install the battery.  These are the presence of any deformation, dent, any leakage, stain, any camber or burr on the sealing parts. These are the signs of the poor health of the battery and may adversely affect the performance. If these signs are present, the batteries are not fit for any commercial use and must be replaced.

Lithium Polymer Batteries are mostly charged to no more than 4.Volts and should not be depleted to less than 3.0 volts per cell. The battery chargers usually come with the battery but can be used interchangeably.

When it comes to battery charging, we all love to charge our batteries as soon as possible. However, for this purpose we might have to buy a special battery charger. These battery charger hubs can charge multiple batteries but varies in specs and can be broadly divided into two types.

Maintaining accurate documentation of Drone Batteries

Use this quick guide to charging your electric RC model battery.

When buying a radio controlled (R/C) car, helicopter, boat or RC motorbike, it’s usually equipped and supplied with a Ni-MH or Li-Po battery and a battery charger.

If you’re looking for the easiest option for keeping your rechargeable batteries full, we recommend the Panasonic Advanced Individual NiMH Battery Charger, which comes with four Eneloop batteries. This simple device doesn’t require any setup and starts charging your batteries accurately as soon as you plug them in. It can charge a single battery (AA or AAA) if need be, unlike some comparable units, which require at least two batteries to work properly.

Pull Quote

The BC-700 displays the status of each battery position on a small LCD and allows you to independently select between three charging speeds.

The Lacrosse BC-700 will help anyone that wants to actively manage their batteries squeeze out every drop of power without adding superfluous features and breaking the bank like the top-of-the-line Powerex WizardOne—but it still costs about twice as much as the Panasonic charger. The BC-700 is based on the same pulsed charging and Negative Delta V detection as the Panasonic above, so you know it’s an accurate, automatic charger. But while the Eneloop charger does everything behind the scenes, the BC-700 displays the status of each battery position on a small LCD and allows you to independently select between three charging speeds as well as a variety of testing and maintenance modes. For most people, the repeated button presses needed to sort through these features will just make rechargeable batteries seem like a chore, but the work can help eke out slightly longer lives and marginally increased capacity if you’re willing to invest the time.

Smart chargers with room for more than four batteries are hard to find, but if you need the extra space, we recommend the Powerex MH-C800S, which can charge any combination of eight AAs and AAAs at a time. If you use a lot of batteries, the Powerex MH-C800S is worth paying extra for. But you should only get it if you really need all eight charging slots from one outlet, since it typically costs about twice as much as the Panasonic.

Unlike the Lacrosse BC-700, the MH-C800S only offers two charging speeds and displays a simple three-bar battery gauge instead of detailed charging information. Plus, it costs around twice the price as our simple pick from Panasonic. We also don’t like that the charger defaults to the faster 1-A charging mode, but a clearly labeled “Soft” button will slow that down to a 500-mA rate, which you should do every time to maximize the number of recharges your batteries can take.

The competition

We passed over the Powerex/Maha Energy MH-C9000 WizardOne Charger-Analyzer. It’s a feature-packed tinkerer’s dream, allowing you to select charge rates up to 2,000 mA at 100-mA increments, and it combines charge and discharge speeds for testing and conditioning—which is why we used it for our own testing for our upcoming rechargeable AA batteries guide. Its display is larger than the Lacrosse units, but it also requires longer button sequences to display info or set up charging profiles. So while it can do more, it also takes longer to do the things you’d normally want to do. Plenty of users swear by this charger, and even those that don’t will admit it’s extremely capable. For most people, though, the extra cost is going to net them extra frustration instead of extra practical features.

Lacrosse also makes a higher-end and lower-end charger in addition to the BC-700, but neither strike us as good a balance of value and usability. The smaller, less expensive BC-500 has a less intuitive one-button interface, doesn’t show as much information, and most importantly, doesn’t have selectable charging currents, instead sticking with 500 mA–the high end of what most experts recommend. Aside from included accessories, the biggest feature gained from moving up to the higher end BC-1000 is incredibly high speed charging. It allows for 1-A charging across all positions, as well as 1.5- and 1.8-A charging for two batteries—all settings we strongly recommend against using since doing so will significantly lower the number of recharges your battery can take.

The Maximal Power FC9Universal Rapid Charger is a large unit that will charge not only NiMH batteries, but also Nickel Cadmium (Ni-CD), Rechargeable Alkaline Manganese (RAM), and (the manufacturer claims) some non-rechargeable alkalines. (This last use is not generally recommended for safety reasons.) Even setting that aside, it offers some of the same control features as our Lacrosse BC-700 pick but with less information monitoring. The Lacrosse is the smaller, more reliable choice.

Like the Maximal unit, the Xtar VCcharges more than just NiMH batteries, also recharging Li-ion 18650 style batteries. These types of rechargeable Li-ion batteries are different from their disposable AA lithium replacements because they have higher voltages required by specific gear, most often camera equipment, and can destroy low voltage gear expecting AA power. The VChas a clear display, multi-stage charging, and selectable current levels. But it doesn’t offer the capacity discharge and recharge test of our Lacrosse pick, and even with a decently powerful USB power supply, some users report power bottlenecks.

Based on specifications, the Foxnovo F-4S is a competent multi-current charger but has a slower, single-button interface to cycle through all the modes. Many users complained about how loud the alert is every time the device finishes a function. No one wants to be woken up at a.m. because their batteries are ready.

Both the Poweradd 903A 4-bay High-Speed Intelligent Battery Charger and the EasyAcc 4-slot AA AAA Battery Charger (now discontinued) are inexpensive and seem as simple as our top pick. But the good user reviews are mostly courtesy of free samples, and we’re not as sure of charging technique and internal logic as we are our pick from Panasonic. If we get more hands-on time, we’ll take a closer look.

The Avalon Battery Charger With Ultra-speed Technology looks and is priced similarly to our pick, but most of the positive reviews we’ve seen have been written in exchange for sample products.

Lithium polymer battery chargers for multirotors

I get a lot of questions about multirotor equipment so I thought I’d start creating some posts about that. Please bear in mind that I learn a lot from reading around the blogs and forums and talking to people in RC shops so any inaccuracies are completely due to my own misunderstanding. By reading this you accept that, although I hope it will aid with your own understanding, it is written in good faith and I can’t take responsibility for any damage to yourself or your equipment that occurs through the use of this information. If you see anything that I have got wrong or you feel is dangerous, please contact me through the HexCam website or Facebook page and I will rectify it as soon as possible. Please treat lithium polymer batteries and multirotors with same respect you would give to other electrical and mechanical equipment. Look after them and they will look after you.

You also need to know the following: I am not paid to review or endorse any products but I do have a partnership arrangement with Versadrones to act as their demonstrator and trainer in the UK.

A step up from the B6

As you can see, with this charger I put in exactly the same settings and am getting a constant 5A charge. So what is the difference? Well, the big 200W on the front gives a major clue. The battery is currently at 23.75V as you can see if you enlarge the photo. Going back to our equation: A = W/V… 200W divided by 23.7is 8.4, so theoretically this charger could charge my 6S lipo at up to 8.4A at this stage of the charge cycle.

This charger will give a maximum 10A charge so I set it to that to see what would happen. As you can see from the next photo, The wattage has become the limiting factor as suspected and we are limited to 8.amps, which on this battery is a 1.7C charge rate (this battery is rated up to 5C charge).

It is completely predictable, if you know your batteries and can use one simple equation you can work out the minimum requirements of your charge system for the batteries you are going to use.

There are variations on these types of charger so that there are multiple chargers in unit. There are a few out there, that are basically four iMax Bchargers in one box. The key thing to look for there is the wattage again, particularly with respect to the maximum wattage each channel can support.

My current charger that I use both in the workshop and out on projects is the Fusion Emperor L712B Pro. This is a two channel charger capable of 500W per channel.

How to Charge a LiPo Battery Safely

When it comes to charging your LiPo battery is very important to never leave a LiPo to charge unsupervised, I have read a few too many stories of fires  starting because someone did not monitor their batteries while they where charging. Most of the time fires start because inferior b-grade LiPo batteries are used. If you use premium brand Lipo batteries such as Gens Ace you will not need to worry as they have all undergone rigorous safety tests and have the certifications to prove it. Here I will discuss a few rules you must follow while charging your batteries.

Before I get into the rules I also wanted to state that I am assuming you are using a LiPo battery charger. If you don’t know much about LiPo battery chargers check out our Lipo charger buying guide.

Never charge your battery unattended – from time to time check to see if your battery is getting warm to the touch or starts to sewll, if so stop charging immediately and contact an expert immediately (like someone on dronetrest) before using the battery again.

Always charge your battery at 1C or less – many chargers allow you to set a charging rate, although most batteries can support up to 5C charge rates (which makes charging your battery much faster). Its always best to charge at 1C or less as this means the chemicals inside your battery will gain energy slower which keeps them more stable and ultimately means your battery will have a much longer life in terms of charge/discharge cycles.

Ensure the number of cells and battery type are set correctly on your charger to match the cell count in your battery. – this is only applicable for more advanced chargers.

During the charge process the battery charger will constantly monitor the voltages of each cell and charge/discharge them to ensure they all the same. This is known as balance charging which all Lipo battery chargers do.

Ensure the batteries are stored at room temperature.

Do not directly connect the terminals with metal objects. This will short-circuit Batteries, resulting in heat and electrical discharge.

Never store loose Batteries together, the Batteries’ terminals may contact one another causing a short circuit.

Specification notes

Regarding the Charge Power of 50 Watts per channel. Remember that Watts=Volts x Amps (Ohm’s Law). So a 3S Lipo has a nominal voltage of 11.1V, which equates out to 4.5A. Whereas a 6S pack=22.2V which results in a charge current of 2.2A.

This is not a problem, if like me, you charge your lipos at 1C and do not want a faster charge. I prefer to have several batteries available, rather than fast charging and I think my packs last a little longer.

Most common objections were

I believe we have covered the majority of these complaints and only the last two are real objections which is a large reason why we have selected this charger as the best for our use.

If you charge at more than 1C, please ensure your battery can take the high current. As I said before, I prefer never to charge at more than 1C and expect my batteries to last a little longer.

A good friend of mine has owned this charger for some time and is very happy with it. He sometimes decides to go flying and puts his batteries on charge then and in a very short time he is ready to go.

Background

First off, parallel charging can be done with LiPo, LiFe, or Li-Ion batteries ONLY.  Do NOT attempt to use this technique with NiCad/NiMH batteries, etc., as they use a peak voltage (ΔV) detection charge technique rather than a constant current/constant voltage (CC/CV) charge technique.  A battery chemistry capable of being charged via the CC/CV technique is a must for parallel charging to be safe and effective.

Different batteries have different rules, however. Currently there are three types of battery in use: Lithium-Ion, Lithium-Polymer and Nickel-Cadmium.

Li-ion Batteries

The most commonly used batteries at present, Li-ion batteries can actually perform better at higher temperatures. The problem with this is that there is a cost: the battery will endure unnecessary stress, reducing the charging capacity.

We’ll have a look at some methods to prolong a Li-ion battery in a moment; before then, take note that super-fast charging and forced discharging (achieved using dedicated apps) is discouraged, as these actions will only shorten the life of your battery.

A finite number of charges is available with any Li-ion battery, which is the recharge cycle or battery cycle you might have seen in documentation. When this limit is reached, you can expect battery life to begin deteriorating. Therefore, charging should become something you do only when the time is right, rather than as a habitual daily/nightly/when the battery hits zero activity.

There are many who keep their battery “topped up”, but the problem is that the battery needs to go through some degree of charging and discharging to stay healthy. A solution is to keep the battery charge somewhere between 50%-80%, which should guarantee optimum performance. Keeping a close watch on the battery level will help here.

Discharging the battery before recharging is a myth of Li-ion that has its roots in NiCd cells (see below for more on this). Your Li-ion device does not have a “memory” and it never needs to be fully discharged.

LiPo Batteries

Lithium-ion Polymer cells are a variation of Lithium-ion, and managing the health of these batteries is the same as for standard Li-ion. Their main advantage is that they can be formed to the shape of the device, rather than having to be placed in a hard rectangular case like Li-ion battery. This makes them better for unibody devices with non-removable batteries.

Many popular phones today use LiPo batteries including the iPhone and HTC One, but all the of the tips that work for Li-ion batteries apply to LiPo batteries as well.

Chargers And Storage

Are you planning on not using your smartphone or tablet for a while? The best option here is to leave it at around 50% charge for a Li-ion battery. Storage should be in a location at the usual room temperature (more on this below).

Also note that damage to your phone’s battery caused by pressure, piercing or the more usual drops can cause the battery to leak, reducing its life and damaging your phone’s circuits.
