Originally interested in regen, but seems 10% recoup doesn't justify cost and complexity.
Is there a source to calculate acceleration given weight and power? This will be my primary design criteria. I need to be able to have reasonable accell in S&G traffic, prob something like 0 - 35mph in maybe 15 secs, for 15 - 20 miles. I need to time it. Everything else will follow.

If you were building a straight EV, I would say that 0-35 in 15 seconds and 15-20 miles is pretty straightforward. You may want to also post to the EVDL (
The Electric Vehicle Discussion List). They are really the source for building EVs.
