"Looks to be" sounds a little discomfiting. I hope you get what you expect.
I see a lot of questionable generic lithium batteries going at tantalizingly
low prices on Ebay and the like, but my caution always kicks in: you don't
always get what you pay for, but you very seldom get what you don't pay for.
This battery is now in service (on an ebike) and has been through a few
cycles. It was a direct replacement as far as form factor. No trouble
so far.
I'm rather eagerly anticipating putting several 36v bicycle batteries in
one or more golf carts. LFP cells are quoted around $1.20 per ah and
the equivalent cost for bicycle batteries is slightly less than $1.20
delivered. BUT that includes a, hopefully, far more reliable BMS. I
have some 20ah 36v 30amp batteries on the way; I envision using about 3
in a golf cart. Also available are 30ah 36v 60amp batteries; two of
those might serve in a golf cart. More later.
A question directed to Cor: Why do bicycle batteries have both charge
and discharge connections?
