...that its going to drain the battery 4x quicker when I'm WOT vs ballistics 13.5

...that there 4x the torque throughout the entire power band vs a ballistics 13.5? Insane acceleration?

Can you use this motor in a MMP?

Please enlighten me...I'm stumped...
You don't use more power than it takes to run the car.

Example: I ran a HV4.5 powered Slash 4X4 13 minutes (until the truck slowed down) on an off-road track using a 4500 mAHr LiFe (Turnigy pack). So my average amp draw was 4.5 / (13/60) = 20.7 amps. The average pack voltage (I know from discharging the LiFes at 20 amps) was about 6.3V. So, on average, the motor was using 131 watts.

I was using a MMP and you can too.
