i would be looking along the lines of a 4 cell pack simply to give me the ability to use it with my heli as well as the car, ie 2 birds with one stone. although i suppose 3 2 cell packs could be used with car. just dont fancy the packs being charged and balanced seperately then run together under high load. could make cells cheaper though running higher voltage and lower capacity, if they get a race saeries going i wonder what they will do about no. of cells
