I bought a 3.5kWh battery for US$450 including delivery and fees directly from China. These prismatic LiFePO4 cells look really good, the quality and packaging is very nice, the specs look great.
I show you the pack and we also go through the main specs of these LFP cells. They come in a pack of 4 so, it’s a 12V battery already right out of the box.

I need more… well, in fact, I’ve already ordered more.
