They've only built two of these things in production. I think it's okay to use forecast costs when it's this early. I assume they'll get better at this, production gets cheaper and the bulk of the material will actually be a logistics cost rather than materials, so putting sticker prices on these might not translate well. But the "smaller prototype" is 8MWh. Their estimate of $25/kWh would make that $200k, and this 100MWh unit should scale to $2.5M but there have already received many times that in funding. Who knows.
