2015 Prius C hybrid battery

Anyone here happen to have ever taken apart a 2015 prius c hybrid battery?

Prius lithium. Don’t know model.

So, the hybrid battery went out in mom’s '15 prius C. “A few bad cells” was the toyota dealer diagnosis. Well, chit, I can replace a few bad cells, but do i want my 83 year old mom driving around on a sketchy pack? What if anothet one or five go tits up? Or i wire it up wrong…

So i think I’ll probably get her a new pack and salvage the good cells from the erroring one for something. Not gem worthy, the pack is too small. Maybe good for dumb stuff like portable lights, tools, remote maching gun turret for killing e825s…

Just looking to find out if anyone chopped one up and any gotchas…

I gave mine away. I can check to see if he tore it down or jot. Pretty useless for us.
From newer car, I think. Do you know what will fit?

Have the cells, but lithium from 2017.
