ok here goes some common sense out the window
a motor is not limited by the esc as much as most think,a motor will take what ever it can get until either the motor/esc/batteries let out the magic smoke.
if you take a motor designed for 300 watts at 7.4 volts its around 40 amps
if you jam 2-3 times the voltage at it you can and will pull 2-3 times that amp draw.
i have data logged 300 watt motors over 2000 watts when fed enough volts
just not for very long.
the esc is not much more than a gate between the battery and motor.
as for batteries a 40c usually wont make much difference at such low amp draw
if there is any difference its because a 40c will have slightly less resistance unless both packs are pre heated
