well my estimates were that my drills pulled 25-30a peak so about 120a max for 4 motors so i looked for something with a higher burst current and the turnigy seemed to give a good burst amp (157a) and there very small and i can do 2 fights on 1 battery
what voltage are you going to use
these are the 1s im using
