LiFePO4 Degradation Scales

The foundation of modern portable energy storage is cell chemistry. The Jackery HomePower 3000 and EcoFlow River 2 both leverage Lithium Iron Phosphate (LiFePO4) cells. Unlike older Lithium-Ion variants (NMC), LiFePO4 chemistry is chemically stable and handles up to 3000 to 4000 full discharge cycles before dropping to 80% original capacity.
