That's a nice easy fix! I might need to add a small inductor to smooth it out, but maybe not.

Cool, that's what I was thinking. Not sure about the inductor though. With no inductor, you'll be drawing pulses of 10A at whatever duty cycle. That might be ok, though. Maybe you just need a slow-blow fuse or something? May take some testing to see if the pulses trip the fuse, but less parts the better.
