Damon,
I think Willie would rather fill his pockets with rocks than use lead
acid batteries if he needed weight. Maybe would put a burro on the seat
beside him.
A flight of fancy here. I could use dead LFP cells for ballast. I have
many. Better, use live hoverboard batteries. I think 36v worth of lead
golf cart batteries weighs 400-500 pounds? Probably around 3.6kwh worth
of available energy. The hoverboard batteries weigh about 2 pounds. So
use 200 to get the same weight. The hb batteries hold about 150 wh.
200 would be 30 kwh. Cost would be about $140/kwh. Quite a pack for a
golf cart or lawn tractor! Might supply ~2000 amps. Unless I've
stumbled on my arithmetic.
