Batteries, Batteries, and more Batteries

Did some more research into batteries, and updated the spreadsheet linked in the previous post. looked at tons of sites and tons of batteries, and decided on this one:

UB12500, with a total pack voltage of 348V, weight of 957 pounds, at a cost of under $2k total hopefully! The range I calculated was 61. I'd like a range of 80+ at least though.

Thought about paralleling NiMH batteries, found a place that had AA NiMH 2600mAh for 75 cents each! This is comparable to lead acid prices. Unfortunately you can't parallel NiMH batteries at least not without a complicated BMS. Is there an easy way to parallel NiMH batteries?
