## Definition

LFP (Lithium Iron Phosphate, LiFePO4) is the safest and most durable lithium chemistry for storage applications. **It withstands 3,000-5,000 cycles at 80% DoD** (vs 500-700 cycles for lead-acid), weighs half as much and has a very stable voltage during discharge. It does not enter thermal runaway (unlike NMC or LCO used in consumer electronics), making it the standard choice for **stationary storage, caravans, marine and as a replacement for deep-cycle lead-acid**. Nominal voltage per cell: 3.2 V → a "12 V LFP" battery has 4 cells and delivers 12.8 V nominal (rising to 13.2-13.6 V during charge). Initial cost 3-4× an equivalent lead-acid, but the cost per cycle is significantly lower. Reference brands: Battle Born, Renogy, Victron Lithium.
