Using LiPo Batteries for FPV Drones: Beginner''s Guide ...
LiPo batteries may have multiple cells. The ''S'' rating on a battery refers to t±±he number of cells it has. So, a 6S battery has six cells, a 4S battery has four, and so on. Because each cell has a nominal voltage of 3.7V, a 4S battery has a nominal voltage of 4 x 3.7V = 14.8V, while a 6S battery has a nominal voltage of 6 x 3.7V = 22.2V.
battery
The 4-connection rule seems to hold even with devices that have multi-cell batteries like cordless drills. Fundamentally, a battery (or single cell) only needs two connections for the battery positive and negative. But what are the other two connections? Thermistor connections to monitor temperature? Signal wires to an embedded protection ...
