Say for instance, we have a 1000w motor on a 6 cell pack:

139A = 1000w / 7.2v

Now, let's upgrade that to a 10 cell pack:

83A = 1000w / 12v

See? The amps went down, not up. If the amps stay the same when the voltage went up, that would mean the motor somehow make more power...which can't happen, because the motor is unchanged.

What this vendor is asserting with their numbers is that the same motor can do more work with more voltage. That makes no sense.

What happen to the motor when you apply more volts?
Hint -> Power=torque*RPM
Torque and Amps are twins...
