I use Venom 3S 11.1V 2100mAh 20C LiPo batteries in 3 of my planes. I want more power/speed and I am confused to what would give me that. In my the planes there are 2 40 Amp ESCs, and a 30 Amp ESC. I have thought about buying a 4S version of the same battery (4S 14.8V 2100mAh 20C), would this give me the added power or would I need to get a higher mAh or C rating? I am just unsure what would give me more power without hurting the ESC. Any help or clarification would be awesome!! Thanks.
