I know NiMH are way easier to charge, but lifepo4 has better capacity and way more charging cycles I believe.
The tricky thing with iron phosphate is that the voltage level between 75-80 and fully charged is very flat, so it’s difficult to reliably know the state of charge.
I started exploring more LiFePo4s, NiMH are sometimes a safer bet. We don’t have many options out there unfortunately.
