Lithium iron phosphate batteries also known as LiFePO4 batteries are one of the safest chemically stable type of lithium rechargeable cells currently available on the market today. They have a slightly lower capacity and nominal voltage than equivalent Li-ion cell but can be charged/discharged around 2000 times versus 500 times for Li-ion and deliver higher peak currents.

The operating temperature range is wider and safer, better power density, low discharge rate, flat discharge curve, low heat and chemically more stable compared to other lithium chemistries.
