4.2 Low Temperature Cut-Off Protection
The battery features an upgraded Low Temperature Cut-Off Protection. The BMS will automatically cut off the charging function if the temperature drops below 19.4℉ (-7℃). Discharge will be cut off if the temperature falls below -4℉ (-20℃). The battery will automatically resume normal operation once the temperature rises to 32℉ (0℃). This feature protects the battery and extends its lifespan.

5. Maintenance
To ensure optimal performance and longevity of your DC HOUSE LiFePO4 battery, follow these general maintenance guidelines:
- Regularly check battery terminals for cleanliness and tightness.
- Keep the battery in a cool, dry, and well-ventilated area.
- Avoid prolonged storage in a fully discharged state.
- If storing for extended periods, ensure the battery is charged to approximately 50% State of Charge (SOC) and periodically check its voltage.
- The integrated BMS helps manage the battery's health, but visual inspections are still recommended.
6. Troubleshooting
The DC HOUSE APP provides a special fault display page to assist in identifying and resolving potential issues. For common problems, refer to the app's diagnostic information.
If the battery automatically cuts off, check the following:
- Low Temperature: If the ambient temperature is below 19.4℉ (-7℃) for charging or -4℉ (-20℃) for discharging, the BMS will activate the low-temperature cut-off. The battery will resume operation when temperatures rise.
- Over-Discharge: The BMS will cut off discharge if the voltage drops below 1V to protect the battery. Recharge the battery as soon as possible.
- Other Faults: Consult the DC HOUSE APP's fault display page for specific error codes or messages.
For persistent issues or complex problems, contact DC HOUSE customer support.
