woulda said its pretty impossibly to say without knowing exact spec, like the voice coil in speakers/subs some can handle 50 watts and some 2000+ it depends massivly the model,
easiest way would be to start with say 4 cells and then add a cell each time and keep an eye on the temp of the motor, if it starts to burn up then loose a cell and stick with that.

wouldnt have thought so, the higher the Mah the longer the batterey will last,
if you want to run th motor at say 12 v you just select the type of batterey and make that voltage up with as many as u need
