I need help with batteries, bms, and chargers. I am converting a 1963 Vespa VBB to electric. I have already purchased
6kW 72V hub motor from Kelly
KEB72801X controller from Kelly
I am happy to be able to go 40-50 mph, but want to have enough juice going up hills in my neighborhood. Range needed is 20-30 miles. Is this somthing you can help me with?
open to sealed lead acid or lifePO4 depending on what I can fit. Was imagining two packs at 36V, one on each side of the rear of the bike behind the cowls. Size may be a problem with lead acid but I am not sure. Looking for range of 30-40 miles (25 min).
Hi, What is a lifepo4 battery? I never heard of that B-4 !
THANK YOU!!! Now I know
