Voltage ratings in drone batteries are indicated by the ‘S’ number, representing the number of cells in series:
- 2S = 7.4V (2 cells)
- 3S = 11.1V (3 cells)
- 4S = 14.8V (4 cells)
- 6S = 22.2V (6 cells)
Higher voltage ratings provide more power and thrust but require appropriate ESCs and motors. Most beginner drones use 2S or 3S batteries, while professional and racing drones often use 4S to 6S for maximum performance. However, higher voltage batteries are heavier and more expensive. Always ensure your drone’s components are compatible with your chosen battery voltage.
