LiPo is the short form used to identify lithium-polymer batteries. They are rechargeable batteries that have become popular among RC users all over the world. These types of batteries are particularly used for planes, helicopters and multirotor or drones.
Lipo batteries are the major reason why electric flight today is a very viable and practical option against the fuel-powered models.
LiPo batteries generally have several features which makes them the ideal and most preferred choice for RC planes and RC helicopters compared to the conventional rechargeable battery types like the NiCad or NiMH.
Almost all LiPo RC battery cells are packaged using a flexible plastic pouch, known as "pouch cell".
These pouch cells are a perfect solution for the building of multi-cell batteries since flat pouch cells can be stacked without the need to waste air spaces like is the case with round cell batteries.
What is the largest Lipo battery?
Many people want to know the highest capacity of the Lipo battery they can get. If you pick any battery, you will see the capacity of the battery written on the label of the battery, so it is fair to think there is a limit for which these types of battery can take.
However, there are no limits theoretically. You can get Lipo cells with very high capacity -any at all. Practically, there is no limit to what you can get depending on the application. As you have known, a larger cell results in a greater capacity. But at a point, it may make more sense to use parallel cells so as not to put all your eggs in one basket.
There are varieties in the different rating of the batteries, and the different application determines the voltage required. When you are set to order your lipo battery, ensure you specify the voltage type of the device, the discharge rate, and the connector type. There is the 4S and 6S lipo battery pack and these are the most commonly used voltage for multirotor drones at the moment.
For a multi-rotor UAV battery, most times, the capacity varies between 10,000 mAh and 30,000 mAh. But what you use or choose depends solely on you.
How does lipo battery last?
Of course, all of us want our batteries and devices to last for as long as possible. But most LiPo batteries are not made to last more than 300 charge cycles. In this context, a full charge cycle is defined as a charged battery, which is then completely discharged and then again, charged to full capacity. However, measuring the lifespan of a LiPo battery may not be as direct or practical as one may think since the batteries go through different depths of the discharge as they are used.
Many manufacturers state that the LiPo batteries they make can last for up to 2 to 3 years. This is to an extent, a more realistic approximation of the lifespan of the battery. And it is more realistic in a situation where the battery is used regularly -including charging and discharging for about two to three times a week.
But then, replacing batteries based on the timestamp may not be applicable in all scenarios because that does not take into account, the usage levels of the battery.
Whatever the level of usage, a LiPo battery begins to "age" immediately it is activated. This holds irrespective of if the battery is used regularly or stored for a longer period. How the performance of a LiPo battery deteriorates during storage depends on the storage conditions.
In summary, a realistic approximation of the lifespan of a LiPo battery should take into account both the number of charge cycles and the age. In all cases, a LiPo battery is considered to have gone past its useful lifespan, once its capacity has been reduced to approximately 80% of its original capacity.
How do you buy the largest Lipo battery with good quality?
To obtain the best usage time and battery performance, it is important to know how to choose the best Lipo battery for your application. To begin with, you should check the manual of your device to know the type of battery the device was built to use. And the specification of the battery as well.
Like most electrical components that make use of power (battery or not), one component is related to another component, and this doesn’t exempt batteries as well. The right battery mainly depends on the size of the application or device for which the battery is to be used (it could be a drone). The type and number of motors used in the application also determine the type of battery to be used in it. In other to know the best quality device to use, follow the simple steps below.
To get the best batteries that will give you peace of mind and enjoy your electronics or devices or flight times, you must use the right battery -with proper consideration to capacity.
Another thing you must be conscious of is the physical size of the Lipo battery, and this also depends on the device you’re using and the space provided for the battery on the device. You must ensure the battery fits in the place meant for it.
This is perhaps the most important point of consideration, but it is an often-overlooked factor that can help in identifying the c rating that is best for your application.
You may completely damage your battery If you use a Lipo battery with a c rating that is too low. That will also affect your device, because the battery may be unable to quickly release current for the device to power it.
This is also one of the most important things you must consider as you shop to select your desired battery. Of course, a higher voltage battery will produce more power for your device. However, since there are more cells in higher voltage batteries, they are always heavier.
You must also consider the battery connector. Since they could be of stress, you just need to find battery connectors you are comfortable with -and then, stick with it.
