Great idea. Let's use highly flammable devices at the end of their useful life to power our largely wooden houses. I'm sure the insurance company won't mind paying when those houses burn to the ground. What could possibly go wrong?

Batteries at "the end of their life" have 80% of their capacity remaining. There is no reason why they can't be put to use, as long as adequate battery management software is implemented.

It's often closer to 60%, but still, it's better than just sending them away for recycling if you know what you're doing.

The article clearly addresses this point. It mentions that many often store their powerwalls outside of their home and have battery manage systems to monitor the health of their powerwalls (i.e. power down when too hot).

If it's not UL listed, you're getting bupkis from insurance if it catches fire. As simple as that.
