I don't know, reading through what people need to do to get their LFP batteries to work sounds like a magical spell being cast...
Top balance the cells
Charge with exactly 3.65v
Dance widdershins 3 times per cell (gets exhausting on 48v banks!)
Wire the extra BMS leads in a anit-clockwise pattern weaving in the name of your favorite eldritch horror/god
Summon the spirit of Harald Bluetooth to speak to the captured spirits of Lithium and Phosphate
Bind the spirits in Iron
Incant the charge profile settings into your SCC
Yup, solar is magic!
