I would think it be the other way around where a 3 cell could handle more load distribution to the servos. What am i missing here?
AMPS, low voltage less resistance more amps, higher voltage more resistance less amps, its the amps that does the Heavy work. thats why using a switching UBEC is better. most esc/bec are Linear, they use a resistor, and are weak, and not a true Amp rating, switching becs are much better, as they use electronics to govenor the amps and volts better. some ESC have switching Becs, but they have to contend with the heat the ESC generates, thats why its better to have a seperate UBEC, Hope that helps, Chellie
