Battery question
My batteries are reaching the end of their good useful life and I am wondering whether to replace them with two 6 volt rather than two 12 volt ones? Would I have to change my inverter, I have a 2012 J...

Why do you not like LiFePO4?GordonThree wrote:
I was marveling at some cells designed for forklifts, 8ah per cell rated for 200a continuous discharge. They were LiFePO4 chemistry though, which I'm not crazy about.
Mostly lower nominal and working voltages
Discharge voltage of 2.5 ... A lot of energy is left on the table unless you can set your low battery cut out down low enough.
Lower energy density is a concern too

NMC offers the same energy per kg as the "dangerous" lithium cobalt cells, but with safety similar to LFP
