I found out about the 4QD site which has a number of handy online calculators. I found out that if I wanted to climb a 60% slope at one mph with a chair + me + trailer + load totalling 1,000 pounds, I could expect to draw 30-35 amps at 48 volts with appropriate gearing, not counting inefficiencies.
Jeff,
I some how missed some of your posts so I went back and scanned them but I guess I'm still not sure what it is you want to do. You want to build your own Super Chair that can tow a trailer? Is that right?
