Fiat Battery

Stumbled on this today. Would it be usable as a backup solar generator battery option? Say they are 24v 60ah. Used for $200. Figured two might work. Since they are car batteries I have no idea if a BMS is onboard (i Assume yes) and what sort of cells are used.

any experience or thoughts would be great

It's probably not what I would choose but i'm sure you can make it work if you put your mind to it.

There will NOT be a BMS in these packs. The 500E is like most other EVs, one BMS for the whole assembly. Nothing can be used separately--you have to get a proper aftermarket BMS to use the cells.

But the price is good--might be worth a try. Usually they sell for more like $350 used and "alleged to test okay", whatever that means.

This character tore apart a 500E full pack. It contains 18 of those modules. Some are 5 cells, some are 6. And a single BMS for the whole thing with nine "supervisor" modules to cover all the modules. 97 cells at 3.7v apiece. He's a doofus but he has obviously done it before.
