Brian is right. Higher voltage equals less current draw with a suitable motor. I used to run a 3000kv motor on 3s lipo in my LS10 and a 80amp continuous battery had trouble keeping up. Now I run 5s thru a quark 65 esc and am using a 5s lipo that can maybe hold up to 50amps continuous. The motor I run now has a kv of around 1800. So I have the smae overall motor rpm, but using more voltage and less amp draw. The battery and motor stay cool, and esc gets warm. Plus I have much more power! 120 amps at 8s would be killer powerful! You would be suprised at how much power high voltage systems can put out!
