6.2 Series and Parallel Connections
This battery can be connected in series or parallel to achieve higher voltage or capacity:
- Series Connection: Connect up to 4 identical Ingeosolly 6V 6Ah LiFePO4 batteries in series to increase the total voltage (e.g., two batteries in series provide 12V). Ensure all batteries are of the same model and charge level before connecting.
- Parallel Connection: Connect batteries in parallel to increase the total capacity (Ah) while maintaining the same voltage. Ensure all batteries are of the same model and charge level before connecting.
Always consult a qualified professional if you are unsure about series or parallel connections.
7. Maintenance
7.1 Charging
- Always use a dedicated LiFePO4 charger. Using chargers designed for other battery chemistries (e.g., lead-acid) can damage the battery or pose safety risks.
- Charge the battery in a well-ventilated area.
- Avoid overcharging or deep discharging the battery, although the integrated BMS provides protection against these conditions.
7.2 Storage
- Store the battery in a cool, dry place, away from direct sunlight and extreme temperatures.
- For long-term storage, charge the battery to approximately 50-70% of its capacity.
- Periodically check the battery's charge level during long-term storage and recharge if necessary to prevent deep discharge.

8. Troubleshooting
If you encounter issues with your Ingeosolly LiFePO4 battery, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not charging | Charger not connected, faulty charger, battery deeply discharged, BMS protection activated. | Ensure charger is properly connected and powered. Try a different compatible charger. If deeply discharged, the BMS might need a specific charger to reactivate. Contact support if issues persist. |
| Battery not providing power | Loose connections, battery discharged, BMS protection activated, faulty device. | Check all connections for tightness. Recharge the battery. If the BMS has activated due to over-discharge or overcurrent, it may need to be reset by connecting to a charger. Test the battery with another compatible device if possible. |
| Reduced runtime | Battery not fully charged, aging battery, high power draw from device. | Ensure the battery is fully charged before use. While LiFePO4 batteries have a long cycle life, capacity can gradually decrease over many years. Consider the power requirements of your device. |
| Battery gets hot during use/charging | Overload, short circuit, faulty charger, high ambient temperature. | Discontinue use/charging immediately. Check for short circuits in the wiring or device. Ensure the charger is compatible. Operate within specified temperature ranges. If overheating persists, contact support. |
