Yeah, really the motor is going to draw about the same amps given the same load despite the voltage (within a reasonable range.) However the inc. in voltage makes much more power. You can try and under gear the motor some, but there are limits to that, and if too under geared you will lose eff there. Besides, why carry around all that extra weight if its not being put to use?

The better way is just to match the motor to the voltage and gear properly. If that kv is correct (I assume it is) then it would be well matched to a 5s batt. What exactly to get depends on your use, but a 5S ~5Ah batt would give great power and good runtime. If you want more runtime or cheaper batts (ie lower C) then go up on Mah. Less weight and sacrifice some runtime get ~25C 4Ah batts. I would get something that could do 110-120A bursts and maybe 75A cont at least. Hopefully you can get something in the 600g range (as low as 450g for hi-C batts, and no more than 800g or so for cheapies.)
