>> Golf cars are pretty economical and reliable with lead golf car batteries. > I can not agree. In my experience, lead in golf carts is FAR more demanding in terms of maintenance. Monthly watering, bad battery connections, corrosion, rusted out battery boxes, general nastiness, ever declining capacity.
Willie, As I said - for sparingly used golf carts there is no need for monthly watering unless you unnecessarily overcharge them. I do about 5k miles per year (mostly freeway) with my truck and I water them no more than 2x per year, sometimes there is almost a year in between waterings. I have 13k mi on them now and no sign of capacity decrease. Agreed that there is a risk of acid spilling and nastiness, but cost and maintenance wise it appears that my flooded pack does much better than your Lithium packs with mini BMS...
