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.
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 sellers in China I have ordered with. I found the quality and customer service outstanding! I have tested the cells for matching voltage, internal resistance and capacity.
