5. Operating Instructions
5.1 Powering On/Off
To power on the battery, ensure all connections are correct, then switch the main power switch (F) to the 'ON' position. The ON/OFF indicator (G) and RUN indicator (J) should illuminate. To power off, switch the main power switch to 'OFF'.
5.2 Monitoring
The battery status can be monitored via a mobile application using Bluetooth or through connected inverters/PCs via CAN/RS485 ports. The mobile app provides real-time data such as voltage, current, State of Charge (SOC), and protection status.

5.3 BMS Protection
The built-in 100A BMS actively protects the battery from various conditions:
- Overcharge Protection: Prevents charging beyond safe voltage limits.
- Over-discharge Protection: Prevents discharging below safe voltage limits.
- Over-current Protection: Safeguards against excessive current draw.
- Short Circuit Protection: Automatically disconnects in case of a short circuit.
- Low/High Temperature Cutoff: Prevents charging or discharging outside safe temperature ranges (e.g., charging cutoff above 149°F / 65°C, low temperature discharge cutoff).

6. Maintenance
The DATOUBOSS LiFePO4 battery requires minimal maintenance. Follow these guidelines to ensure optimal performance and lifespan:
- Regularly inspect terminals for corrosion and ensure connections are tight.
- Keep the battery clean and free from dust and debris.
- Ensure adequate ventilation around the battery.
- Avoid operating the battery outside its specified temperature range. The BMS will provide protection, but consistent extreme conditions can reduce lifespan.
- For long-term storage, store the battery at approximately 50% State of Charge (SOC) in a cool, dry place.
7. Troubleshooting
If you encounter issues with your DATOUBOSS battery, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not powering on | Power switch off, 125A breaker tripped, loose connections, deeply discharged battery. | Check power switch (F) and 125A breaker (E). Verify all cable connections. If deeply discharged, attempt to charge with a compatible charger. |
| ALM indicator (K) is lit | BMS protection activated (e.g., over-voltage, under-voltage, over-current, temperature). | Check battery status via the mobile app or connected inverter for specific fault codes. Address the underlying cause (e.g., reduce load, adjust charging parameters, allow battery to cool/warm). Press the Reset button (H) if safe to do so after resolving the issue. |
| No communication with inverter/app | Incorrect cable connection, wrong communication settings, app not paired. | Verify communication cable connections (CAN, RS485, RS232). Ensure correct communication protocols and settings are configured on both the battery and the inverter. For Bluetooth, ensure the app is correctly paired. |
| Reduced capacity or runtime | Aging battery, consistent deep cycling, operating in extreme temperatures. | While LiFePO4 batteries have a long lifespan, capacity naturally degrades over many cycles. Ensure proper charging/discharging practices and avoid prolonged exposure to extreme temperatures. |
If the problem persists after following these steps, please contact DATOUBOSS customer support for further assistance.
