High voltage is a better etup because it pulls less amps, say you want to make 100 watts of power, you could do high amp setup which would be 100amps and 1 volt of power. or the high voltage route say 100volts and 1amp of power, the lower the kv motor, the higher the voltage can be.... The higher voltage it is, means the less amps it draws. so you can run very high voltage setups that pull very little amps and have wayy better run time. hope this helps
