Description
Item Specification Description/Remark : Model AT-LFP-48-50BV01 48V 50Ah LiFePO4 battery, 70A continuous
discharge rate.
Chemistry: Lithium Iron Phosphate (LiFePO4)
Battery dimensions: 490mm x 171mm x 240mm (L x W x H)
Weight: 23.2kg
Cell type: 3.2V 50Ah
Battery module: 16 pcs 3.2V 50Ah cells, 1 parallel and 16 serial
Casing material for single cell Aluminum casing
Standard capacity(0.2C5A)51.2V 50Ah / 2560Wh
Cycle life: > 2000 cycles at 100% Depth of
Discharge (DoD) with the battery capacity retention ≥ 80%
Under normal usage where the DOD is <80%, cycle life is expected to be up to 5000 cycles
Rated voltage 51.2V Working voltage per cell: 3.2V
Max charge voltage 57.6V Max. charge voltage per cell: 3.6V
Cut-off voltage 40-44.8V
Battery cells are disconnected once the lowest cell reaches 2.50V
Depth of Discharge: (DoD) 100% Batteries can be discharged to 100% of the rated capacity
Standard charge current: 10A 0.2C
Rapid charging Max. charge current 50A (1C)
Temperature increase falling within 15°C is normal. Over 15°C will affect the service life of the cells.
Max continuous discharge current 70A 1.4C
Peak discharge current 140A 2.8C
Discharge performance in normal temperature 10A (0.2C3A) ≥ 100% 50A (1C3A) ≥90%
