4. Setup and Installation
4.1 Initial Inspection
Upon receiving your battery, inspect it for any visible damage. If damage is found, contact ExpertPower support immediately.
4.2 Terminal Connections
Ensure all connections are secure and properly tightened. Use appropriate M8 terminals and cables rated for the expected current. Incorrect or loose connections can lead to overheating and damage.
- Connect the positive (+) terminal of the battery to the positive (+) terminal of your load/charger.
- Connect the negative (-) terminal of the battery to the negative (-) terminal of your load/charger.
- Always use a fuse or circuit breaker appropriate for your system's current draw to protect the battery and connected equipment.
4.3 Series and Parallel Connections
The ExpertPower 12V 100Ah LiFePO4 battery supports expansion for increased voltage or capacity:
- Series Connection: Up to 4 batteries can be connected in series to achieve a 48V 100Ah system.
- Parallel Connection: Up to 10 batteries can be connected in parallel to achieve a 12V 1000Ah system.
When connecting batteries in series or parallel, ensure all batteries are of the same model, capacity, and state of charge. Consult a qualified technician for complex installations.

7. Troubleshooting
The built-in Battery Management System (BMS) is designed to protect the battery from various fault conditions. If the battery appears to be non-functional, it may be due to a BMS protection trigger.
Common Issues and BMS Protections:
- No Output/Input: The BMS may have activated due to overcharge, deep discharge, overcurrent, or temperature extremes. Disconnect the load/charger and allow the battery to rest. Reconnect a compatible charger to reset the BMS if it was triggered by deep discharge.
- Inverter Surge: Some inverters may cause a surge that triggers the BMS. Consider using a soft-start mechanism or a resistor in the negative line when first powering up high-wattage inverters to prevent this.
- Unbalanced Cells: The BMS includes an auto cell balancing feature. If cell imbalance is detected, the BMS may temporarily halt charging or discharging until balance is restored.
- Temperature Protection: The BMS will prevent charging below 32°F (0°C) and discharging below -4°F (-20°C) or above 140°F (60°C) to protect the cells. Move the battery to a suitable temperature environment.
For persistent issues or complex troubleshooting, refer to the ExpertPower website or contact customer support.
