Decided and purchasing battery for EV!

So, updated battery spreadsheet again. Changed the assumed Wh needed per mile, costs, etc, to better hopefully reflect reality, and to make the numbers more on the conservative side. Settled on UB12350 batteries, 29 of them for a 348V system, of 696 pounds weight, with a energy storage capacity of 8526kW. Assuming 250Wh per mile, this gives a 34 mile range, which is ok for now, at least until lithium technology becomes cheaper. Hopefully that will be soon! Lots of interesting technologies out there, from Firefly and AltairNano, etc.
