Plugging your details into JVN's drive train calculator: http://www.chiefdelphi.com/media/papers/2059

I assumed 2 CIM motors per side, 6 inch wheels, 1.3 coefficient of friction, and a single gear reduction of 10 and 35 (to get to 40 fps). This shows a total current draw of over 1000 amps. If all the right circuit breakers were installed correctly, you should be tripping them very quickly.

Did you mean 13 feet per second
yes thats what i meant that is the second time I've done that this year. I blame my physics teacher

Re: Battery Drain Issues

Thanks for the help the issue was resolved we had a bad connection at the main breaker, along with all of our batteries not being at peak charge. The drive base performs wonderfully and we should have some pics or a video up soon.
