LiFePO4 battery cells (LFP-cells) are now commonly used in solar storage projects as well as in electric vehicles. These cells have a lower voltage of 3.2V than for example Lithium Cobalt cells with 3.7V and also have a lower energy density but are very good in terms of cycling and voltage drop. Their cycle life can be up to 10x higher than for NMC cells.

– 280Ah Cells
– 100Ah Cells

Prismatic LiFePO4 cells, EVE 3.2V, 280Ah, 896Wh
These high-capacity cells are great and ideal for your solar storage projects. 4 of them in series will make the perfect 12V battery with over 3.5kWh of capacity. You will see me using these cells a lot. All details of these cells are in the link below.
Below are affiliate links directly to two manufacturers I have order with in China. I found the quality and customer service outstanding. In the video below, I tested the cells for matching voltage, internal resistance and capacity.
Some people reported problems with the link. Please try the below links from a desktop computer, not mobile. One of the links should always work. If you’re opening the link below with the mobile app from Alibaba, there should be a ‘Continue to website‘ link (or similar) at the bottom of your app. Please click that to continue to the product website.
