LiFePO4 Cells (LFP)

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 they are very good in terms of cycling and voltage drop. Their cycle life can be up to 10x higher than for NMC cells.

Prismatic LiFePO4 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 links below.


Below are affiliate links directly to the EVE Power Co manufacturer of the cells (A-Grade and certified cells) as well as resellers on Alibaba which sell the EVE cells which did not pass the A-Grade quality control. These cheaper cells are still great for solar storage and DIY projects. Please confirm with the resellers what you get BEFORE you buy, so the product meets your expectations. So far, I have only ordered from these resellers, not from EVE directly. I have tested the cells for matching voltage, internal resistance and capacity. They wer all very good and reliable cells.
Some people reported problems with the links below. Please try the 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 actual product website.
