How to take care your Batteries ? to read the number [666] Published:2016-01-08 14:51:04

One of the most important point your FPV needs to fly is the battery that powers all the electronics. 

No battery, no flying. The type of battery 

most widely used today in radio controlled vehicles is the Lithium Polymer. 

They supply high power with light weight ; 

Now it's essential to know a few basic properties of LiPo batteries and techniques to properly charge, store 

Look at your LiPo you may see something like this written on it:

eg: 3S1P 11.1V, 2200mAh, 25C discharge/50C Burst, 5C max charge

What does that tell you ? 

LiPo batteries are made up of cells. The number of cells a LiPo battery has is labeled with an “S” number and/or by its Voltage (V). A 1S LiPo is a 1 cell battery with a voltage of 3.7V. 

Most drones operate with a 3S or 4S LiPo. A 3S LiPo has 3 cells and a discharged voltage of 11.1V and a 4S LiPo has 4 cells and a discharged voltage of 14.8V. Here is a chart of the most common size of LiPos encountered in the drone world.

1S = 1 cell and 3.7V

2S = 2 cells and 7.4V

3S = 3 cells and 11.1V

4S = 4 cells and 14.8V

5S = 5 cells and 18.5V

6S = 6 cells and 22.2V
