RC LiPo Batteries see extensive use since the recent past. These batteries are designed specifically for remote controlled vehicles like drones. The LiPo technology in the batteries allows for enough power to be packed in a small amount of space. Having a lightweight battery design is of utmost importance as it allows for longer flight times, higher flight speeds, and more precise maneuverability. However, there is a lot of confusion surrounding the life span of RC LiPo batteries, and we are here to clear your doubts.
As you keep using a LiPo battery on your drone, the battery capacity will slowly drain. Let us assume that your done battery was marked at 4000mAh out of the box; you can expect it to drop to 75% of its marked capacity in about 200 discharge cycles or so. A LiPo battery normally lasts about 300 to 500 discharge cycles depending on how well you maintain your drone. Considering the fact that drones are often put through harsh operating conditions, battery life may also be affected.
Maximizing Life Span of RC LiPo batteries
The most basic thing you can do is maintain the proper charge voltage. If you go past the 4.2V per cell charging threshold, it can cause serious damage to your battery. More importantly, it is also important to not over-discharge your battery. It is recommended to recharge your battery before it fully drains out.
If you plan on keeping your drone away for an extended period of time, you should never keep your battery fully charged. Most importantly, you should always use a balanced charger for maximum safety.
