  • Average number of cycles for lithium iron phosphate battery pack

    Average number of cycles for lithium iron phosphate battery pack

    When evaluating Lithium Iron Phosphate (LFP) batteries, you'll often encounter two key durability benchmarks: an 8,000-cycle life to 70% State of Health (SOH) at a specific test rate, and alternatively, 6,000 cycles at an 80% Depth of Discharge (DOD). Quick Answer: LiFePO4 battery cycle life — also known as the life cycle of a lithium iron phosphate (LFP) battery — determines how many times it can be charged and discharged before its capacity drops significantly. While these figures may seem different at first. For instance, Taking PLB's IFR26650-30B battery as an example : a battery's cycle life at 100% DoD is ≥3000 cycles, at 80% DoD is ≥6000 cycles, and at 50% DoD is ≥8000 cycles. Notably, many batteries on the market omit the DoD when specifying cycle life, necessitating careful consideration. This value is calculated at 80% Depth of Discharge.
