“3S LiPo” refers to a specific type of LiPo (Lithium Polymer) battery configuration. The “3S” designation indicates the number of cells connected in series within the battery pack.

Each LiPo cell has a nominal voltage of 3.7 volts. When multiple cells are connected in series, their voltages add up. Therefore, a 3S LiPo battery pack consists of three LiPo cells connected in series, resulting in a nominal voltage of 11.1 volts (3.7V x 3).

Here’s a breakdown of the terminology:

“S” stands for “Series.” It indicates that the cells are connected end-to-end, with the positive terminal of one cell connected to the negative terminal of the next cell.

The number before “S” indicates the number of cells connected in series.

The cell count in a LiPo battery pack is an important specification as it determines the overall voltage of the pack. Different devices and applications require specific voltage levels, and the cell count helps determine if a particular LiPo battery is compatible.

In addition to the cell count, LiPo batteries also have a “C-rating” that represents their discharge rate. The C-rating indicates the maximum sustainable discharge current relative to the battery’s capacity. For example, a 3S LiPo battery with a 2200mAh capacity and a 25C rating can sustain a discharge current of 25 times its capacity, which is 55 amps (2200mAh x 25).

It’s important to note that LiPo batteries require proper handling, storage, and charging practices to ensure safety and longevity. Always follow the manufacturer’s guidelines and safety precautions when working with LiPo batteries.
