I have an Alltrax 400amp controller, but the Etek's only rated to 330amps, so I used that number. I've heard of people running them up to 480 amps and 96 volts (which would be about 63hp x 2 = 126hp) but I'd only expect them to last a few quarter mile passes at that load and speed. If you want to do the math, they make about 1.2 inch-pounds per amp (some list it as 1.14).

That Swift is cool.
