What's going on with sodium ion battery availability in the west?

USA perspective:
I haven't seen it in evehicles yet.
In UPS or 'lithium generator' applications, i just see bluetti selling a unit, and a couple random sellers.
The Bluetti unit is pretty expensive.

I see frequently enough some articles about it being in Chinese cars and things, have you ever seen it in anything here... or some of the nicer density cells, even?

Sriko sells them:

I've bought stuff from them before, but not sodium ion cells. I'd like the extra safety, but the ~1.5-4V range per cell is a PITA. Like I'd have to replace all my electronics to handle higher voltage ranges for when the cells are full just so the pack isn't useless when it's down to 2V per cell. Probably would need a new motor with a different KV too.

I've bought JBD BMS from Sriko as they ship quick out of Illinois, but their website throws off alarms for the past year and my browser won't give access. I've emailed them and they haveblt fixed it at their end,
