It’s certainly possible, but is it worth it?

EV batteries tend to use some of the best technology available in order to get power density and energy density where they need to be. A house battery can be much bigger and heavier if that makes it cheaper.

Somebody at work was just telling me about some efforts to reuse e.g. Tesla battery packs for home or grid storage rather than recycling them. Even if the pack can only hold 80% of its original charge, that’s fine if you can just buy a few of those cheaply.
