2. Battery Operating Limits
2.1 Maximum Battery Operating Limits
The battery should not be operated outside the Maximum Operating Limits, the BMS will open its internal relay and disconnect the
battery if any of the following limits are exceeded.
Maximum Operating Limits 44-24-2800 42-48-6650
Continuous Charge Current* 110 Adc 130 Adc
Continuous Discharge Current* 110 Adc 130 Adc
Charge Voltage 27.2 V 54.4 V
Operating Voltage (Min / Max) 22.4 V / 29.2 V 44.8 V / 58.4 V
Charge Temperature (Min / Max) 0°C / 45°C (32°F / 113°F)
Discharge Temperature (Min / Max) -20°C / 50°C (-4°F / 122°F)
Storage Temperature (Min / Max) -20°C / 45°C (-4°F / 113°F)
* Eects of AC Ripple must be taken into consideration when sizing and conguring your system.
2.2 Current Protections
The programmed over current protections of the BMS follow the curves seen in the next two gures:
▲ NOTE!
Intentional bypassing of BMS to operate the battery
outside maximum and minimum limits voids warranty.
2.3 Recommended Battery Operating Limits
The battery maximum operating limits are specied for DC current and voltage and do not account for AC ripple typically caused
by frequency conversion electronics such as inverter/chargers. The following operating limits are recommended for these types of
systems.
Recommended Operating Settings 44-24-2800 42-48-6650
Max Continuous Charge Current < 78 A < 92 A
Max Continuous Discharge Current < 78 A < 92 A
Charge Voltage (Bulk/Absorb) 27.2 V 54.4 V
Charge Voltage (Float) 26.8 V 53.6 V
Low Voltage Disconnect 24 V 48 V
Operating Temperature 20°C (68°F)
