There's something I've been wondering about . . . Since it sounds like some people run DC series forklift motors up to 10x their rated voltage, would it be too unreasonable for to operate two motors (placed in mechanical series) each at 200V? Using a leaf battery system, at about 380V (unless I want to really get in there and rewire everything) it seems like running these motors off of this battery in ELECTRICAL series as well would place both motors near 200V ~ within the reasonable realm?
