> Lifepo4 (lithium iron phosphate) batteries for the home are pretty cheap as of today. Power storage for residential use in a 48v metal rackable linkable system with battery management system (BMS) is $89/kwh shipped/duty paid from reputable chinese suppliers CATL/Seplos etc.

I'm probably not the only one wondering: does ordering from these Chinese suppliers require reaching out to them over email? I looked at both websites, and while Seplos asks to write in, CATL doesn't even have battery listings or sales contact information.

I'd love to order LiFePo4 batteries to put in some old UPSes of mine.

you can order through Alibaba, but there are so many suppliers and not all are reputable, so it's a good idea to search around on some of the solar forums for recommendations.

Yeah I think if you want to order from CATL directly, your chances for a reply are better if your order is worth some billions :-)

EVE cells are very famous in the DIY scene, you can get them via Alibaba/Aliexpress, or if you're in Europe from nkon.nl, they have a very good reputation.
