5. Setup
- Unpacking and Inspection: Carefully remove the battery cells from their packaging. Inspect each cell for any visible damage, such as dents, leaks, or swollen cases. Do not use damaged cells.
- Initial Voltage Check: Before connecting, measure the voltage of each cell to ensure they are within a healthy range (typically around 3.2V - 3.3V).
- Cell Balancing: For optimal performance and longevity, it is highly recommended to balance all cells before initial use, especially when building a battery pack. This ensures that the internal resistance, voltage, and capacity of each cell are closely matched.
- Connection: Connect the cells in series or parallel as required for your application. Use the provided M6 nuts and bus bars to create secure, low-resistance connections. Ensure correct polarity (+ to - for series, + to + and - to - for parallel). Do not overtighten the nuts.
- BMS Installation (Recommended): For battery packs, install a Battery Management System (BMS) to monitor cell voltage, temperature, and current, providing protection against overcharge, over-discharge, overcurrent, and short circuits.
- Initial Charge: After assembly and BMS installation (if applicable), perform an initial charge using a compatible LiFePO4 charger.

7. Maintenance
- Regular Inspection: Periodically check the battery cells and connections for any signs of corrosion, loose terminals, or physical damage.
- Terminal Cleaning: If corrosion is present, carefully clean the terminals with a wire brush and a baking soda solution, then rinse with distilled water and dry thoroughly.
- Voltage Monitoring: For battery packs, regularly monitor individual cell voltages to ensure they remain balanced. Re-balance if significant discrepancies are observed.
- Storage: If storing the batteries for an extended period, charge them to approximately 50% state of charge (around 3.25V per cell) and store in a cool, dry place away from direct sunlight and extreme temperatures.
- Avoid Deep Discharge: While LiFePO4 batteries tolerate deep discharge, consistently avoiding it can extend their lifespan.
8. Troubleshooting
If you encounter issues with your LiFePO4 battery cells, consider the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not charging | Faulty charger, loose connections, BMS protection triggered, deeply discharged cell | Check charger functionality and connections. Inspect BMS status. Attempt a slow, low-current charge if deeply discharged. |
| Low voltage output | Over-discharge, unbalanced cells, internal cell damage | Check individual cell voltages. Balance cells. If a cell is damaged, it may need replacement. |
| Battery pack overheating | Overcurrent, poor ventilation, internal short circuit | Reduce load. Ensure adequate airflow. Disconnect immediately if severe and seek professional help. |
| Reduced capacity/runtime | Aging cells, unbalanced cells, consistent deep discharge | Balance cells. Review usage patterns. Consider cell replacement if significant degradation. |
If you are unable to resolve an issue, please contact customer support.
