Notes |
| Continuous Discharge current |
200A |
|
1C continuous |
| Surge Discharge Current – 30 seconds |
600A |
|
3C transient. Typically repeated for every lift or peak load. |
| Electronic Current trip limit – analogue |
|
550A |
If the electronic current limit option is enabled – Note 1* |
| Electronic trip Retry time – analogue |
|
– |
Time taken after current trip to retry connection |
| Pre-Charge current limit – Note 1* |
|
550A |
Automatically provided if electronic current limit is enabled |
| Electronic Overload – Digital |
|
|
Optional with either, I²t , max current, or Custom profiles |
| Internal Battery Fuse |
400A |
|
I²t = 610 000 A |
| Minimum battery voltage |
47.2V |
|
Battery will cutout here, regardless of indicated SOC |
| ABSOLUTE Minimum Battery Voltage |
|
43.4V |
Internal electronics Disabled! Please see battery protection. |
Note 1*. Electronic current limit is optional and adjustable between 500-1000A. It will act as a automatic pre-charge for connection to inverters. For motive applications, in particular old lead machines, pre-charge or current limit prevents startup, and not desirable.
Charge Limits - (and charger settings)
| Charge Limits – (and charger settings) |
| Maximum Continuous Charging Current |
150A |
Preferred range is 100A to 150A, set for constant current CC. |
| End of Charge voltage |
56V |
55.6V to 56.0V max set as endpoint CV voltage |
| Balancing charge voltage or current |
56.2V |
56.0V-56.3V OR charge at constant current (CC) of 400mA |
| Charger voltage range |
48V |
Charger voltage must be within normal 48V limits. |
| Battery maximum voltage self cut out |
56.4V |
Battery will cutout, preventing further charging, NOTE 3*. |
| Peak transient charger voltage |
100V |
*Peak transient voltage after battery self disconnects |
| Charger Lead Inductive Energy |
75J |
NOTE 4*. However, Typical 2m length lead installations are of no concern. |
| NOTE 3*. If battery self cuts out from over voltage it will still be available for discharge through reverse diode. |
NOTE 4*. This is the maximum charger lead Inductive energy battery cutout can absorb ( 1/2 I²L < 75J ).
NOTE 1*. When the internal electronics are disabled, the battery enters a dormant state. In this state the battery will be inactive, not connected and not available for normal recharge or use. It can be recharged but it MUST be recharged with a constant current that must not exceed 500mA (450mA preferred) and voltage less than 65V (e.g. Balancell hockey PUK charger). If left for more than 6 months in this dormant state, then it should NOT be recharged and battery needs to be returned for a service and cell checkup.
