volts/amps question

[speed demon]

OK thanks. I'm running a medusa 35-50-2200v2 and it says 700watts 75 amps and 22 max volts. Running the numbers 75amps at 22volts is waaaay more then 700watts. I was playing around with it today and ran a 3S for awhile and checked temps..MM was 110 and the motor was 98. Put in my 4S and and the temps rose to..MM 136 and motor 116. Figured since temps were running that low I might just run a 5S. I can see the motor raising temps because of higher rpms but I couldn't figure out why the MM would get hotter well really warmer.

Sorry still trying to get a handle on all this stuff. Thanks
