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.

Rated A is the manufacturer's continuous figure; Mooch A is independently measured and usually lower. Where they disagree, size to Mooch.
LFP packs need a charger and BMS matched to the 3.2V nominal cell voltage. Check the BMS Picker for compatible options.
