Oh joy, I just love paying more for freeloaders![]()
Solid state in the sense that they aren't flooded lead acid, yes.
But yes, the LiFePo4 (lithium iron phosphate) chemistry is the one that won't light on fire. They are the current favorite for safety in solar systems.
Some of the newer chemistries like lithium titanate are intriguing, but still expensive.
Do you all realize that Denver is 1.5 billion dollars in debt, and that each of you owe $17,000 to cover this debt?
What the hell do you care if socialized government says that you have to pay more for energy?
Grant do you spot weld your own cells?
You sir, are a specialist in the art of discovering a welcoming outcome of a particular situation....not a mechanic.
My feedback add 11-12 ish before the great servpocaylpse of 2012
For this solar stuff, no. I am using 280AH CALB cells.
The only picture I have quickly available, from when I was moving it to its new home in the garage.

For other projects (solar power for cameras in the back yard, lights in the shed, E-Dirtbike, etc) yes. I build and weld my own packs of 18650 and 32650 Li-ion and LiFePo4 cells. I have a number of cheap spot welders, one that I built, and then I also finally bought a k-weld. I got into salvaging cells for a while, and considered building 48V arrays for the house solar (not as crazy as HBPowerWall on Youtube, but similar idea). Way too many battery packs disassembled and cleaned up... Last count, I think I have 3k+ 18650's that I pulled out of "failed" laptop batteries...
9x 80 cell packs when I was planning a 14s80p 48V battery.
