A battery for my Prodeco bicycle turned up dead. The OEM replacement

~10ah. Has anyone heard of anyone doing cell replacements?
Thanks for the responses! Cors' was especially valuable. I had hoped
to be pointed to some battery repair service such as exists for hybrid
batteries.
The guy working on the bike reported that all cells were bad. I didn't
believe him and talked him into opening the case. He wasn't able to get
access to all cells without tearing the case up but the two he did get
access to seemed good. I have a battery that looks to be a direct
replacement coming from China. I don't want to fool with a battery that
does not conform to the form factor of the original battery.
Hijacking my own thread:
In looking for bike batteries, it occurred to me that a bunch of them
might make a suitable golf cart battery. My golf carts, with 100ah LFP
cells and miniBMS have been FAR too costly to maintain. I've been toying
with "lead replacement" batteries that protect themselves from over
charging and over discharging. So, several of those might work in a
golf cart and not give me the repair/maintenance headache I have now. I
wonder if the bike batteries also protect themselves?
The "lead replacements" cost around $4/ah/cell while the bike batteries
can go as low as about $1.50/ah/cell.
I sometimes use 100 amps (@~36v) in a golf cart but I believe I can get
by on 80 amps. Assuming a bike battery will do 1C, four 36v 20ah
batteries might serve me. I might start with two just to see what
trouble I encounter before I spend too much money.
IF the bike batteries protect themselves from over charging, I could
charge with regular golf cart chargers. Else, I could charge with one
or several bike chargers.
