Not a clue

The 6.5 claims to be 91% efficient, although that must vary with the temperature of the windings/rotor?

Lets try 370w power output with 91% efficiency, that'd be 407w input and the remaining 37w released as heat/noise. That gives 55 amps draw, not including esc/power wire resistance losses...

To the original question...
The 3200's will be fine, in my experience the 3200 gives a similar feel to a good NiMh pack in terms of punch but is lighter
