If people want to get one for the hell of it, I'm not going to stand in their way, but I really don't think that this product plays well to the strength of sodium-ion batteries.
My understanding is that sodium-ion batteries are not as energy-dense, but are expected to be cheaper per-kilowatt-hour than lithium-based batteries.
But this is a small, very-expensive-relative-to-storage-capacity, portable battery.
I'd think that sodium-ion batteries would be more interesting for things like an alternative to this sort of thing
large-capacity, mostly-non-moved-around batteries used for home backup during power outages, stuff like that. Maybe grid buffering.
As in a reasonable replacement to Tesla home batteries?
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.
