Let me know when I can buy 30kwh worth of energy storage so I can compare it to Lifepo4 costs [1]

Those are the more expensive packs with LCDs. The cheaper, simpler packs are only $9000 and just as good.

LiFePO4 batteries are really magical; mostly made of easy-to-find materials, good density, long lifetime, hard to make explode.

LiFeYPO4 Have a wide temperature range of -45° to 85° C. Uses Yttriumbut cost more
