5. Setup and Installation
Proper setup is crucial for optimal performance and safety. Always ensure all connections are secure and correct polarity is observed.
5.1 Initial Charging
It is recommended to fully charge the battery before its first use. Use a compatible LiFePO4 charger with a charging voltage of 14.6V.
5.2 Connecting to an Inverter
- Ensure the inverter is turned OFF.
- Connect the positive (+) terminal of the battery to the positive (+) input of the inverter using appropriate gauge cables.
- Connect the negative (-) terminal of the battery to the negative (-) input of the inverter.
- Secure all connections tightly using the M8 terminal bolts.
- Once connections are secure, you may turn on the inverter.
5.3 Series and Parallel Connections (Capacity Expansion)
The DATOUBOSS 12V 300Ah LiFePO4 battery supports both series and parallel connections to expand voltage or capacity. Always ensure all batteries are of the same type, capacity, and state of charge before connecting.
- Parallel Connection: Connect positive to positive and negative to negative terminals to increase total capacity (Ah) while maintaining 12V. For example, connecting four 12V 300Ah batteries in parallel creates a 12V 1200Ah system.
- Series Connection: Connect the positive terminal of one battery to the negative terminal of the next to increase total voltage. For example, connecting four 12V 300Ah batteries in series creates a 48V 300Ah system.
- Series-Parallel (4S4P): For large-scale systems, you can combine series and parallel connections. For instance, a 4S4P configuration with 12V 300Ah batteries can create a 51.2V 1200Ah system with 61.44kWh usable energy.

8. Troubleshooting
If you encounter issues with your DATOUBOSS LiFePO4 battery, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not charging | Incorrect charger, loose connections, BMS protection activated (e.g., low temperature cut-off) | Verify charger compatibility and connections. Check ambient temperature. If BMS is active, allow battery to warm up or cool down. |
| No power output | Loose connections, BMS protection activated (e.g., over-discharge, overcurrent, short circuit), battery fully discharged | Check all connections. Recharge the battery if discharged. Disconnect load if overcurrent/short circuit protection is active, then reconnect. |
| Battery overheating | Excessive load, poor ventilation, high ambient temperature | Reduce load. Ensure adequate ventilation around the battery. Move to a cooler environment if possible. The BMS will typically shut down the battery if temperatures exceed safe limits. |
| Unusual odors or swelling | Internal damage, severe malfunction | Immediately disconnect the battery from all loads and chargers. Do not attempt to use or repair. Contact customer support. |
