My high school physics tells me that Power (Watts) = Current (amp) * Potential (volts).
So, my XM-2000 states that it has a 40 amp controller and 60 volt battery pack. That means peak power would be 2400 Watts. Now, given that the speed and distance specs are "optimistic" I find it strange that the power rating would be pessimistic.
So, can anyone explain how the XM-2000 gets its 2000 Watt rating? Is it to do with motor efficiency? Or complete system efficiency? (i.e. losses in the battery, controller, wire and motor) This would make the system about 83% efficient - 2400 * 0.83 = 1992. That sounds plausible.
