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.
