Batteries are essentially self-contained power sources, and the main part of a battery is the cell. This cell consists two electrodes, one positive and one negative, along with a solution called electrolyte that serves as the source of a chemical reaction that relays electricity, and thereby power, to the electrodes on either end.

7 Best 3s and 2s LiPo Batteries

Venom  - Best 3S Lipo Battery

The Venom 20C 3S is a great option if you are looking for something long-lasting for your drone. If you are the kind of person that wants your drone to cover long distances, this is the LiPo battery for you.

The great thing about this battery is that it contains three cells, hence the 3S in the name. This means that you have triple the time you would have otherwise. Furthermore, the efficiency with which this battery has been manufactured ensures that it remains light in spite of the long-lasting effects it has.

The battery also discharges quite quickly, making it easy for you to get it charged up and ready to go again with ease. One benefit of this battery that is quite noticeable is how cool it stays no matter how long you use it.

Overheating is a common problem faced by a lot of LiPo batteries, but the solid polymer electrolyte used here is so efficient that you are really not going to face any troubles using it as far as heat is concerned. This is important because it can prevent your machine from getting damaged, as would be the case with batteries that tend to overheat.

Perhaps the best thing about this battery is how it manages to efficiently provide power to your car without sacrificing speed or agility. This battery manages to give your vehicle the kick it needs to run at maximum speed while maintaining a cool outer casing, and the low charging times are also something you are going to truly appreciate.

If there is one problem with this battery, it's the overall bulkiness you are going to have to deal with. However, this is something easily remedied as long as you make sure your car is compatible.

Floureon 2 - Best Lipo Battery for RC Cars

This two-pack dual series battery is a great midrange option if you are looking for a powerful battery that does not take too long to charge up. With a lot of batteries that offer power, charge times can be a real issue.

However, the construction of this battery has replaced the hard outer casing often used for a softer one, which means less resistance during the charging process. Hence, the solid polymer becomes a lot more adept at absorbing electricity, resulting in an efficient chemical reaction.

This battery uses a JST-XH connector which is compatible with a great number of drones and motorized vehicles. This compatibility ensures that you can swap the battery around with your various gadgets rather than having to use a different one each and every time - a very significant benefit if you ask me.

While using this battery, I noticed that there was a fair amount of heat coming off of the surface. This was a problem but one that is quickly solved when it is discharged. The discharging process is swift and efficient and once discharged, the battery cools down very quickly indeed.

The affordable price range for this battery along with the stellar customer service offered makes it a great option for someone looking for an entry-level LiPo power source that would not break the bank and would be easy to use for a long period of time.

Gens Ace 

This battery is on the lighter side, which is a great boon if you are using it on a boat. When using this battery, it is important to note that the lightness makes a difference to the velocity of the boat or car, thus forcing you to readjust your usage based on the new weight.

This is not a problem at all when you consider that it actually allows your boat or car to move a lot faster.

One other thing that I noticed while using it was that it was quite efficient at dispatching power. A short charge time can get a great deal of battery life, so if you charge the battery up for about fifteen minutes, you can expect about an hour and a half of battery life.

Another thing to note is the fact that it comes with a hard case. Soft cases can be a real pain to manage as they can cause the battery to get damaged even if you are careful, so the fact that you are getting a hard case here gives you a lot of value with your purchase overall.

The quick charging aside, has been specifically designed for models such as the Traxxas Slash, so if you are looking for a LiPo power source that is suited to your specific needs, you have found it right here. Just bear in mind that the light weight and hard case make for a less efficient charging situation if you are looking for long-term use.

It works best in short bursts in spite of the high cycle life, but this is not a problem for vehicles such as the Traxxas Slash, as you would not be needing longevity with such models anyway.


This three-cell powerhouse has a lot of pep to it. You can use it in burst mode or standard mode, giving your drone or car a turbo boost of energy or allowing you to use it at normal speeds depending on your preference.

The soft case that it comes in may be easily damaged so you would have to handle this with care, but bear in mind that it comes with the added benefit of its low weight. Weight is an important factor when it comes to selecting, and the efficiency of the cells along with the low weight of the overall structure can help you get some pretty incredible speeds from your car overall.

A full charge does not take very long at all and can give you up to fifteen minutes of flight time with a standard drone. This comes from the very high C rating that this battery has received, so you can use it for those fun afternoons flying your drone around and rest easy in the knowledge that short charges are going to get you a great deal of battery life that can result in some fun drone flying sessions.

However, the soft packaging can often be a problem if you do not take proper care of your battery. Not being careful can result in cell damage in a short amount of time.

This is more often than not the result of improper use, though, so as long as you take care of the LiPo battery and make sure that it does not get knocked around too much, you won't have to worry about anything getting broken or damaged. The benefits of this battery are numerous and are sure to help you make the most of your drone flying experience.

Venom 25C - Best 2S Lipo Battery

One of the best things about the Venom 25C 2S is the fact that it has a universal plug. Having to fiddle about with adapters when you get a plug that needs a specific kind of socket can be a real hassle and can take a lot away from your experience of using a Traxxas, so getting a universal plug here will definitely allow you to get a more intuitive and user-friendly experience from this LiPo battery.

This battery also gives you some serious longevity as far as the life of your product is concerned. If you spend the money it would take to get the Venom 25C, you can pretty much rest assured that you have the perfect battery for all of your needs for at least a couple of years.

Take good care of the battery, and you are looking at a lifetime of over four years, twice as long as some of the best LiPo batteries provided by other brands.

One thing that might make you a little uncertain about whether or not this battery is right for you is the price. A price this high is often a sign that your battery is just banking on brand value, but in this case, it’s actually worth it.

This is because this battery is so versatile that it can fit into any device, and the lightweight, compact casing it comes in would ensure that you never have any trouble taking it along with you when you are off to use your drone. The only thing you will have to worry about is a slightly longer than average charging time, which is not really a problem when you consider how efficient this battery truly is.

All in all, there is very little about this LiPo battery that you are going to have trouble with, which is what makes it one of the best LiPo batteries money can buy.

Traxxas 2872X 

The Traxxas 2872X is specifically designed to work with Traxxas models, giving you a great battery that is pretty much streamlined for your specific use if you are using related products.

The wiring is soldered right into the cell wall, resulting in a much more efficient charging situation with charge times being very low and helping you get a great deal of use time out of them.

One of the reasons that this battery is so efficient has to do with the fact that the discharge tabs are wider than they normally are. This makes the discharge of power through the electrodes a lot more efficient while allowing control of power to ensure that your machine never ends up getting damaged in any way.

Overheating also becomes a less common problem with the wider discharge tabs, as these tabs tend to disperse the heat produced by the chemical reactions in a much more even manner.

The connectors are also soldered into the body of this battery rather than being connected via wires. This is a great feature as it allows you to get a lot more efficiency during charging while making this battery a lot longer lasting as there are no flimsy wires that could easily break at any time.

This helps give the battery a longer lifetime, as wear and tear is inevitable and the less susceptible your battery is, the longer you are going to be able to use it.

The only real problem with this battery, apart from the fact that it’s not quite as light as it should be, is that it is not all that compatible with models from other brands, but you are probably not going to be buying this to use with other brands.

Getting this battery can be a great help to you while you are using various Traxxas models, no matter what model you happen to be using. The efficient charging and high efficiency of discharge allow you to make the most of this battery.

Tattu 75C 

This lightweight battery is a great option if you are not looking for something heavy-duty but prefer efficiency instead. If you are using drones, weight can be a real issue. Using this battery would allow you to get maximum efficiency as your drone would not get weighed down by the mass of its battery. It can also help improve the buoyancy of your boat.

The lightweight structure of this battery has virtually no impact on its efficiency, however. This is a quick charging battery, with a few minutes of charging getting you up to fifteen minutes of power for your drone. Another thing to appreciate is the sturdy casing.

Soft though it may be, this casing manages to provide a great amount of support for the battery, allowing it to withstand a little bit of rough treatment. If you’re clumsy like me, this firm casing can be a huge boon as it would help you get a much longer lifespan.

The light weight has a drawback though; this is a battery that does not have a lot of power, but then again, if you are going for something so compact, power is probably not what you are looking for.

One thing that a lot of people tend to overlook when they are buying a battery is customer service. It is important to go for a company that provides stellar customer service as anything could go wrong at any time.

One thing you are certainly going to love when you get this battery is how friendly and cooperative the customer service agents are.

No matter what issue you might have, giving customer service a call will have your problems resolved in no time at all. The amount of relief you are going to get from this battery is incalculable and really emphasizes what a wonderful battery this is.

This electrolyte is usually composed of lithium salts. However, in lithium polymer batteries, the electrolyte is instead made up of a solid polymer such as polyethylene oxide. This has a dramatic effect on how LiPo batteries produce power and is the defining feature that makes these batteries so different from other kinds of batteries.

One of the main reasons that these batteries tend to be better than standard batteries has to do with the fact that they are lighter and, thus, more portable. Technology is becoming increasingly streamlined, so batteries that are less bulky are becoming preferable.

In addition to this, these batteries tend to be used in vehicles or other motorized objects whose objective is to travel at as fast a speed as possible.

Thus, the fact that these batteries are so light helps make them a better option as they would not compromise the speed of the machine you are using in any way. A big part of the reason why these rc batteries tend to be lighter is that they don't have hard cases. The solid polymer electrolyte can be stored in soft cases and covers as it does not need any kind of covering to help maintain its form.

The functionality of LiPo batteries also tends to be more efficient than other types of batteries out there. One example of this can be seen in how long they last. They generally last longer than other batteries while managing to get recharged in a far shorter amount of time. Check this out if want to increase the battery life of your lipo even longer.

This is thanks to the replacement of lithium salts with solid polymers, which are much more efficient at both obtaining electrical charges quickly and dispatching them via chemical reactions slowly, making for a much longer battery life.

Charging Capacity

Lithium-Ion Polymer batteries also generally tend to have a much higher charging capacity, often going three or four times higher than other batteries. This makes them a great option for long usage, as they would enable you to get the battery life you need.

Since these batteries tend to get charged far more quickly, you would not have to spend extra time getting to full charging capacity either, thus making LiPo batteries time-savers as well as high-capacity power suppliers that you can use for extended periods of time.

In addition to this, LiPo batteries tend not to suffer from the memory effect. This refers to the impact that extended charging or use over a long period of time can have on some batteries. As time passes by, a lot of batteries tend to become far less efficient at holding charge. Hence, you would have to charge these batteries for increasingly longer periods while getting a poorer result each time you use them.

Lithium Ion Polymer batteries tend not to suffer from this problem. The solid polymer electrolyte does not depreciate in quality. It does not get damaged even after extended periods of charging. Thus, this makes it easier for you to get long use from your LiPo battery.

Unique Electrolytes

The main differences that Lithium Ion Polymer batteries have when compared to other batteries have to do with the unique electrolytes that are used within the chamber. This electrolyte is a great deal more efficient than the lithium salts most other batteries tend to use, which is why using this battery is a really great idea.

Potential Cons

There are certain things to keep in mind. First and foremost, the soft packaging that these batteries come in can often get pretty easily damaged.

This can be a real problem in the long run and it is something you are going to have to keep in mind while you are using this kind of battery. In addition, you would find that such batteries are more expensive than other kinds of batteries simply because it costs more to produce them.

However, the myriad benefits that you would receive when you start using LiPo batteries certainly outweigh any problems you might face. The higher price point is the result of these batteries being created to a much higher standard and as long as you take care of your rc battery, you can rest assured that you are going to get a great experience that would be long lasting.

Since these batteries last so long, you would find that the higher price point would actually not matter at all in the long run. This is why these batteries are so amazing, and it is why you should seriously look into getting yourself the best LiPo battery that you can find as soon as possible.

Difference Between A 3S and 2S Lipo Battery?

The main difference between the 3S lipo and the 2s is the voltage. For the 3S you get 11.1 voltage while for the 2 Cell lipo you get 7.4 volts. Due to having more voltage using the 3S is faster. 

2S = Two cells in series

3S = Three cells in series​

​Now obviously 2S tend to be cheaper. 

Things to Look Out For In Lithium Polymer Batteries

Buying the right battery is a huge step that can determine whether or not you would get the optimum experience from your drone or whatever device you need to power. Hence, when you make the decision to buy a certain battery, you need to make sure that it is an educated one.

In order to know that the battery you are buying is the right one for you, just keep the following points in mind. These are things you should look out for before buying:


Cell Count

If you are planning on operating heavy-duty machinery that requires a lot of power, you need to get a LiPo battery with a higher cell count. The number of cells a battery has is proportional to the amount of voltage it can produce.

This means that a battery with a higher cell count would be more powerful than one with a lower cell count. However, the more cells a battery has, the heavier it is, which means you should be careful when buying one for a drone or something that needs a lightweight battery.



Capacity determines how much battery life your LiPo power source is going to have. Longer sessions require a LiPo battery with a larger capacity, and most heavy-duty cars and drones would need a 5000 milliampere battery if you want to get a decent battery life.

There are higher capacities available as well, but you should try to find a balance as batteries that have too high a capacity can actually end up having a heating problem. This can damage your device if it's not heat resistant, so keep this in mind. 


C Rating

The C rating refers to the discharge rate of your battery. If a battery has a higher C rating, it means that it has a higher discharge rate, which means a lower battery life but more power for your drone or car. A C rating that's too low can result in your device getting damaged or not functioning properly, and one that's too high could result in overheating.

You should try your best to find a sweet spot with your battery's discharge rate so that you don't have to worry about overheating or lack of power damaging your machine.


Internal Resistance

This term refers to how much energy is lost due to the imperfect conductivity of any electrode. Unlike the other things you need to look out for, internal resistance is pretty straightforward. You should get the battery with the lowest internal resistance as this would give you the most efficient distribution of energy.

The only real problem with low IR batteries is that the low resistance comes from a lack of hard casing, which can make the battery fragile. However, the benefits you get in exchange are well worth it and you can always be more careful with your battery, so low IR batteries are the way to go.



This really depends on the type of performance you want from your battery. In general, a heavier battery would be more powerful though slower to charge, and a lighter battery would be easier to charge though less powerful of course.

Generally, lighter batteries tend to have longer battery lives but are not as sturdy as heavier ones. If you are piloting a drone, lighter batteries will work best. If it's a car you are using the battery with, going for a heavier battery will give you the power you need to use it for the long term.



You should take special care not to get a battery that has a specific charger. You are not always going to get the same kind of socket everywhere you go, so go for batteries that have a universal charger or at least one that is going to function properly in a number of different situations.

Unless you are getting a branded battery that is custom-built for the model you are using, getting a battery with a universal or versatile charger is a good idea as it would help you make the most of your machine.


Battery Connector

What you need is a battery connector that is perfect for your device. Batteries come and go, but if you want to change your battery connector, you are going to have to undergo a complicated soldering process that would take a lot of time and have a large margin for error.

You can even damage your machine if you are not careful while soldering. Hence, you should find a battery connector that goes perfectly with your machine and fits all of your standards and specifications, and stick to it so that you don't have to go through so much hassle.



The brand you buy can have an impact on your overall experience. If you are using a model from a specific big name brand, it would be a good idea to get a battery designed by and for that brand as it would give you a customized experience.

You should also make sure you buy from brands that have a record of providing excellent customer service. This would help you get the most out of your battery as you would have someone to talk to if anything goes wrong or you need help setting up.
