new non sulphating battery from Soneil

Time will tell with drop in style. I'm using 100ah prismatic cells. 4s5p configuration of 20 cells (500ah/ 6,400wh). I think they're better than what you describe of the multiple little cells made into a battery container.

Being able to see cell individual temps is important.
