yes I meant NMC ...NMH? You mean NMCNickel metal hydride went out ages ago...
My tesla has an LFP battery and it defaults the charge to 100% (the NMC ones default to 80)
article I'd read https://www.dekra.se/en/how-electric-car-batteries-differ-in-performance-across-types/
so the essential 100% charging strategy seems to offset the expected life cycle gains of LFP .
