So, your battery amps are 5000W / 100V = 50A. So the motor is seeing 100A but the battery pack is only seeing 50A.
Is this correct?
edit: added pwm controller info

PWM causes a lot of strangeness in the real world so we will ignore it.
On my 48v car I can typically get up to 30mph @ 65amps or so (summer)
If I were to peg the car to make the motor have 24v (whatever that takes as PWM percentages don't really match directly to a neat voltage realationship on most motors)
I would end up driving about 16-18mph at about half the amps.
Real world this is what I observe battery side, my guess (and its probably right) is in my circumstance the motor amps are also slightly reduced because the aero loss is less.
