I am trying to design a battery powered utility cart that runs on a track. I have found some motors that would work for the drive wheels, but they require 130VDC to operate. Is this doable with a batteries? There would be 5 of these motors each drawing about 3.3A (about 16.5A total). Seems I could put about 11 12V batteries in series but I have never worked with such high DC voltage before.
