Cell-pack under-temperature protection has tripped. Listed in the FAULT row of the LED table on page 7 as 'CELL TEMPERATURE LOW'.
Cell temperature below the allowed range — charging is permitted only between 0 and +55 degC, discharging between -20 and +65 degC (section 2.3 spec).
Warm the battery to within the operating range before resuming use. Do not install or operate in an environment below 0 degC (section 1.3 item 14).
Battery Manual LPBF48250 (EN).pdf · page 7FAULT: LED1=OFF, LED2=ON, LED3=ON, LED4=OFF (Green OFF, Red ON)Discharging Current High.Défaut
Discharge over-current protection has tripped; output is disabled. Listed in the FAULT row of the LED table on page 7 as 'DISCHARGING CURRENT HIGH'.
Load drew more current than the recommended discharge limit (recommended <=120 A, MAX 200 A for 15 s per section 2.3) or a short circuit on the DC output. Section 1.3 item 11 warns NEVER to cause AC output / DC input short circuits.
Remove or reduce the load, check the DC output wiring for short circuits, and restart the pack. For loads above 6 kVA install at least 2 packs in parallel (section 1.3 item 9). MAX. Output Power is 10 000 W; recommended output power is 6 000 W (section 2.3).
Battery Manual LPBF48250 (EN).pdf · page 7FAULT: LED1=ON, LED2=OFF, LED3=OFF, LED4=OFF (Green OFF, Red ON)Battery Voltage High.Défaut
Pack-level over-voltage protection has tripped; output is disabled. Listed in the FAULT row of the LED table on page 7 as 'BATTERY VOLTAGE HIGH'.
Pack voltage exceeded the BMS over-voltage threshold during charging — e.g. charger output above the recommended Max. Charging Voltage of 57.6 V (section 2.4).
Stop charging, verify the charger / inverter Max. Charging Voltage and Floating Charging Voltage are set to 57.6 V per section 2.4, and allow the pack voltage to fall back into the 48-57.6 V range before re-enabling output.
Battery Manual LPBF48250 (EN).pdf · page 7FAULT: LED1=ON, LED2=OFF, LED3=OFF, LED4=ON (Green OFF, Red ON)Cell Temperature High.Défaut
Cell-pack over-temperature protection has tripped. Listed in the FAULT row of the LED table on page 7 as 'CELL TEMPERATURE HIGH'.
Cells heated above the safe operating temperature. Per the section 2.3 spec the working temperature range is Discharge -20 to +65 degC and Charge 0 to +55 degC; this fault trips when cells exceed those limits.
Stop charging / discharging, let the pack cool, and improve ventilation. if the fault persists at normal ambient temperature, contact the supplier for service (section 1.3 items 3 and 12 — only qualified service persons may open the unit).
Battery Manual LPBF48250 (EN).pdf · page 7FAULT: LED1=ON, LED2=OFF, LED3=ON, LED4=OFF (Green OFF, Red ON)Charging Current High.Défaut
Charge over-current protection has tripped. Listed in the FAULT row of the LED table on page 7 as 'CHARGING CURRENT HIGH'.
Charge current exceeded the recommended limit. Per section 2.3 the recommended charge & discharge current is <=120 A and the absolute MAX is 200 A for 15 s; per section 2.4 Max. Charging Current is 120 A * N (N = number of packs in parallel). The protection trips when these limits are exceeded.
Reduce the charge current at the charger / inverter to within 120 A per pack (section 2.4). For inverters larger than 6 kVA, install at least 2 sets of LPBF48V in parallel connection (section 1.3 item 9 and section 3.2).
Battery Manual LPBF48250 (EN).pdf · page 7FAULT: LED1=ON, LED2=ON, LED3=OFF, LED4=OFF (Green OFF, Red ON)Cell Voltage High.Défaut
Individual-cell over-voltage protection has tripped; one or more cells have exceeded the upper cell-voltage limit. Listed in the FAULT row of the LED table on page 7 as 'CELL VOLTAGE HIGH'.
Cell imbalance during charging, or a charger setting that allows individual cells to drift above their safe ceiling.
Stop charging, allow the BMS to balance the cells, and review charger / inverter charge-voltage settings against section 2.4 (Max. Charging Voltage 57.6 V). if the condition persists the pack may need service — only qualified personnel may open the unit (section 1.3, items 3 and 12).
Battery Manual LPBF48250 (EN).pdf · page 7FAULT: LED1=ON, LED2=ON, LED3=OFF, LED4=ON (Green OFF, Red ON)Current Sensor Abnormal.Critique
BMS current-sensor diagnostic failure; the pack cannot reliably measure charge / discharge current. Listed in the FAULT row of the LED table on page 7 as 'CURRENT SENSOR ABNOMAL' (sic in source).
Internal current-sensor fault or wiring problem on the BMS board.
Power-cycle the pack (press and hold On/Off for 3 s to shut down per section 4.1, then re-enable). if the fault persists, do not continue to use the unit — section 1.3 items 3 and 12 require that only qualified service persons service the device. Contact your supplier per the warranty / damaged-battery guidance in section 5.

BMS / electronics over-temperature protection has tripped. Listed in the FAULT row of the LED table on page 7 as 'BMS TEMPERATURE HIGH'.
Insufficient ventilation around the unit, ambient temperature too high, or sustained high charge / discharge current heating the BMS board. Per section 1.3 item 14 the unit must not be installed above 55 degC ambient or above 80% humidity; per section 3.2 the recommended ambient range is 0-45 degC.
Stop charging / discharging and let the unit cool. Improve ventilation and ensure clearances around the unit per the section 3.2 mounting diagram, and verify ambient is within 0-45 degC.
