Discharge Limits – (Voltage & Current) Battery Protection 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)
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 ).
