wow, I keep seeing the ~
200 vextrix motors on ebay.
It will be interesting to see if it still resembles a vectrix after you strap 18 leaf cells to it
(~2.5* the original 3.7kwh). I'm still slowly sorting out reconfiguring the cells for 33ah/15v, but that might be an approach of interest for you as well (9 cells @ 135v, 33ah, 4.5kwh), though looks are secondary at most if you get ~125 mile range with stock cells.
Looking forward to seeing how it shapes up!
