Using half-worn car battery packs seems optimal for home use.
I’m not putting cobalt based (NMC or NCA) batteries inside my house. Thats nearly exclusively what car battery packs are. Thermal runaway is too great a risk to bolt that much energy to a wall in the house. I am comfortable with LFP in the house though.

It is. Some of them are getting snapped up to help with powering factories.
I think this is car companies using the incoming battery packs from replacing worn out packs. Time to look it up…
