A 6s3p configuration means the battery is assembled from six cells connected in series and three parallel rows. This setup provides a nominal voltage of 21.6 V and increased capacity — in the BTRY 6s3p Molicel INR21700-P45B model, it reaches 13,500 mAh, with peak current up to 135 A. This makes the battery capable of supporting both long flights and peak loads in demanding conditions.Unlike the 6s2p configuration, the 6s3p variant offers more energy reserve without a critical increase in weight. It’s an optimal solution for strike FPV drones, reconnaissance platforms with elevated load, and copters equipped with additional systems.
