I think the normal practice is for a company to announce a new product and then in about two or three weeks announce a new customer for that product.  That gives them 2 PRs instead of one.  There is a lot of testing to be done and UL certification also.  So,  2023 will be the year of the solid state battery.

The rest of this year should be the start of bus battery sales.  Just a trickle at first as the OEMs are ramping production up from nothing.

I am thinking the truck battery sales to Vicinity should start April this year.
