The minimum voltage that you can give the controller for driving the car is 0, and the maximum is about 150v. At 0 volts, your top speed will be pretty low. hehe. But the controller would be perfectly happy with, say, a AA 1.5v battery as the power source for the motor. That's the beauty of powering the controller with the 12v auxiliary battery (but using an isolated DC-DC converter inside the controller). Absolute flexibility with the pack voltage! ya! And if someone uses 600v IGBTs, diodes and caps? Then the allowable battery pack voltage would be 0 to about 550v or so. Otmar, the Zilla maker, suggested to me that isolated DC-DC that we're using.
