The WarP9 motor I plan on using is rated for no more than 156v (or so). I plan on running 144v but all of the performance charts only show power usage at 72v. Can I just double (or halve) those numbers to get ratings at 144v?

My understanding of DC motors is that higher voltages allow higher speeds, but higher amperage allows more torque.
I'll admit I don't understand how that works, but Paul Holmes demonstrated it in his controller build thread.
