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.
