|
> 2000 cycles at 100% Depth of Discharge (DoD)
|
Cycle life
|
Under normal usage where the DOD is <80%, cycle life is expected to be up to  5000 cycles
|
Rated voltage
|
12.8V
|
Working voltage per cell: 3.2V
|
Charge voltage
|
14.4 - 14.6V
|
Max. charge voltage per cell: 3.65V
|
Cut-off volate
|
2.5V for lowest cell, nominal 10V
|
Cut-off is triggered when the first cell reaches 2.50V
|
Depth of discharge (DoD)
|
100%
|
Batteries can be discharged to 100% of the rated capacity
|
Standard charge current
|
50A
|
0.25C
|
Charging time
|
Approximately 5 hours
|
When charging from low voltage cut-off point
|
Optimum charge current range
|
20A (0.2C5A) to 100A (1C3A)
|
Cell max voltage < 3.9V
|
Rapid charging
|
Max. charge current 200A (1C3A)
|
Temperature increase falling within 15°C is normal. Over 15°C will affect the service life of the cells.
