On First blush these load curves are perfect for Evercells!!!
Cutting your battery weight by %60 is a rather impressive concept!!
How hot does it get in the "Vehicle"???
Life line Batteries are Concordes. Good ones. Low amperage, Sealed lead
Acid. Reg are REQUIRED!!!.
I have seen a couple strings Die early because of the lack of a good
charger and Regs.
Serious efforts brought many back to life.
