LiFePO4 Battery CyclenBatt Mini 12.8V 100AH - Nice - $105 (Gilbert)
QR Code Link to This Post
It is one year old and works great. I purchased several last year at this time for a solar project I was working on. We moved to a smaller house and now I don't have room for them.
Fits nice inside a Group 24 battery box (I have a couple boxes available for $20 each)
The battery is fully charged and ready to use.
Here's what AI says about them:
LiFePO4 (Lithium Iron Phosphate) batteries offer significantly longer lifespan, lighter weight, and higher efficiency than traditional lead-acid batteries, though lead-acid costs less upfront.
