Like, the Powerwall things? Yeah, sure, they’re in the same sort of class. I think — not gonna go looking through all of 'em — that the things I linked to above all are intended to have someone plug devices directly into them, and the Powerwalls get wired into the electrical panel, but same basic idea. They aren’t really devices where energy density matters all that much, because once you put the battery somewhere, it probably isn’t going to move much after that.
As in a reasonable replacement to Tesla home batteries?
