Was actually hoping to just buy some scooter batteries (10AH) since my daily commute is only about 4 miles and I can charge at work, I was hoping to get away with about $30 per cell (3 total)... not sure if this is realistic.

I know I'll eventually go with lithium, but I'm going to wait and see if prices come down in the next year or so. Then again, if SLA ends up running much more than $100 i'll probably just end up taking your suggestion. Being new to this, my instinct is to get everything up and running, and then let UGI takeover
