+ some Sodium cells further down…
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 sellers of LiFePO4 cells and packs that have been proven to be reliable and with great quality. People ask me all the time where to buy these cells I’m showing in my video. Well, there you go.
I have ordered from Alibaba many times and it is safe to do so. You can either pay with credit card or Paypal which both is safe to do. There are true A-Grade Certified cells or Storage Grade cells you can choose from. 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. I have tested the cells for matching voltage, internal resistance and capacity. They wer all very good and reliable cells.

My experience ordering from Alibaba:
Thread repair for stripped M6 Terminals for EVE LF280 and LF304 cells
Simply use the UNC set screw below and slowly drive it into the stripped terminal.
Set screw: 1/4″ UNC (coarse)
Thread: 20TPI
Length: 1″ (or longer)
You need the 1/4″ UNC nut as well as the original M6 will not fit any more.
No pre-drilling, no re-threading needed. Bombenfest!
Watch the video on how to do it here.
