LFP (Lithium Iron Phosphate) Cells
LFP (lithium iron phosphate) cells have a lower nominal voltage than NMC or NCA but offer better thermal stability, longer cycle life, and a safer chemistry overall. They are popular in DIY powerwall and stationary storage builds where cycle count matters more than energy density.
