I have nothing wrong with going higher voltage. The main thing I was looking at was the biggest PMAC controller I could find was 48V at 250 amps max. I like the regen and less maintenance that combo listed gives me.
So what about if I doubled the motors up and ran 2 of them at 250 amps each? That is getting expensive at 3000 bucks for the pair but if that is basically my main problem then that still keeps me within my more or less arbitrary $5000 budget I picked.
I did move my spare metro up to my garage today so this week if I have time I will take a lot of the body and extra crap off it so I can start figuring out where to put the motor. I might have room to put two motors or not really have enough room for one. I will find out soon I guess
