Have these been independently tested with production form factors? Battery startups seem to have a lot of middle-level fraud in them where they have nice demonstration piddly level cells with great numbers that the internal teams know won't scale to real uses.

I did see they are actually funding a factory... but I only saw a couple stories on "wearables" which implies very small batteries. Ugh, and a SPAC.

I really want these various startups to succeed much like I actually wanted Nikola Motors to succeed and Lordstown to succeed, but the Tesla stock explosion is going to bring these hype-shells out of the woodwork.
