Description LiFePO4 12.8v Suitable for “12v” systems Features Active and Passive cell balancing BMS continuous discharge: 300A BMS Max Charge Rate: 200A Recommended Standard Constant Charge Rate: 100A BMS over current protection: 320A for 10 seconds, reset 35 seconds. BMS over current protection: 205A for 10 seconds, reset 35 seconds. Low voltage discharge shut down: 10v restart 10.5v High Voltage charge disconnect: 15v restart 14.8v Low temp charge disconnect: 1c reset 2c Low temp discharge disconnect -20c reset -15c High temp charge disconnect: 55c reset 50c High temp discharge disconnect: 60c reset 55c Charging Bulk Charge: 14.2V – 14.6V (ideal: 14.4V) Absorption: 14.2V – 14.6V (ideal: 14.4V) Float: 13.4V – 13.6V (ideal: 13.5V) Terminal size: M10 Case made from zinc plated and powder coated steel The automotive-grade cells used in this model are designed to withstand 3000 cycles at 80% depth of discharge under heavy electric vehicle use. For  instance, cycling the battery daily—bringing  it down to 20% state of  charge and fully recharging it—would take  approximately 8.2 years to  complete 3000 cycles before the battery is  regarded as end of life,  degrading to 80% of its original capacity while  remaining operational  for some time thereafter.  In less demanding applications such as caravan storage, you can expect  longer cycle life.
