Watts = Amps x Volts
So say you need 750 watts to do 40mph (just a guess, some one else might say different).
At 7.4 volts you'll need 101 amps (740 / 7.4 = 101)
That's alot, I think the limmit of the MM is 100amps, so you'll burn it out pretty quick. Plus axcellerating will take more amps (if your batteries can handle it).
At 11.1 volt you'll need 68 amps, plus more for acellerating. Still a lot for the hole system.
At 14.8 volt you'll need 50 amps. Still a lot, but no where near as much as 100 amps.
These numbers aren't 100% accurate, but you get the idea.

With high current low voltage everything will get hotter. And your batteries will drop voltage more with the high amps, making the car feel less powerful on take off.
