3.2V 280Ah LiFePO4 (4PCS) LITHIUM IRON PHOSPHATE BATTERY CELLS BOAT RV SOLAR

  

Brand new grade "A" EVE LF280K 3.2V, 280Ah, LiFePo4 Battery cells 4 pcs. With four 250A copper busbars and eight stainless steel M6 nuts. Stainless steel laser-welded terminal screw posts have a substantial advantage over just aluminum terminals because allow screwing cables with a bigger force and better electric contact.

All cells have an actual capacity that exceeds 280Ah. See also the picture of our own capacity test. Residual cell's voltage was 2.65V (voltmeter in the capacity tester is not very accurate). Constant discharge current up to 1C (280A). 6000+ discharge cycles (80% discharge at 77F).

Equivalent to the capacity of 2 regular 280Ah lead-acid batteries. LiFePo4 battery technology offers much longer lifespans than lead-acid batteries, while offering more safeguards than traditional lithium-ion batteries. This translates into reliable cost savings in the long-run. Other advantages of LiFePO4 batteries. Maintain constant voltage throughout discharge cycle. Four cells in series connection form 12.8V 280Ah battery. To add a BMS circuit board. Please do not hesitate to ask should you have any technical questions! Cycle Life >6000 cycles at 0.2C 80% DOD. Charge Voltage 3.65 V. Max Charge Current 280A (1C) 2C for 30S. Max Pulse Discharge Current 2C for 30S. Charge Cut-off Voltage 2.5V. Charge Temperature 32F - 131F at 60% Relative Humidity. Discharge Temperature -4F - 140F at 60% Relative Humidity. Storage Temperature -4F - 113F. Dimensions 6.83" X 2.84" X 8.17 (whith studs) (174.7mm X 71.5mm X 215mm). With proper use, the life span of LiFePo4 cells can be more than 10 years. Use a proper BMS for your battery, do not charge these cells with a temperature below 32 F, avoid short circuits and mechanical damages, periodically control cell's balancing in your battery, within an inactive period store your battery at 50%-70% SOC, and the cool temperature.

Keep in mind, that the high storage temperature lowers LiFePo4 cells capacity over time. Four 250A tinned copper busbars.
