What is the best battery for off grid solar systems?

Introducing LiFePo4 CALB CA180FI, this is the best battery of all batteries out there you can get for your off grid solar system today. If you have a better cell hit me back, I'll be happy to consider / discus your option.
You can still get these at cycle-charge.com/vladk ...use this link for 10% off any order

The Chinese writing on the side suggests these are for aircraft power systems.
I love these, no compression necessary and the casing is not conductive. I think these batteries could outlive your fridge or freezer

NOT SURE ABOUT THAT BUT THEY ARE GOOD

agreed , i have the 100ah . lost one cell out of 16s went completely dead. hard to find replacements where i live. CALB does seem to be the cream of the crop as far as durability and quality control goes. terminals are solid but the little red and black plastic around the terminals will not last. ive experienced some swelling but not so much. the cell i lost was a new one. havent lost any of my used cells

That’s interesting

I use gel marine batteries, no LiPOFe4s.

Congratulations

How many charge cycles do they have?

[@VladFredK]

About 1500

@@VladFredKthat’s if you push the battery in all specs. If you don’t charge or discharge them all the way, or if you don’t push them to max current charge or discharge, they’ll go way way way longer
