4. Setup
Proper setup is crucial for the performance and longevity of your battery. Ensure all connections are secure and correctly polarized.
- Unpacking and Inspection: Carefully remove the battery from its packaging. Inspect for any visible damage. If damaged, contact customer support immediately.
- Mounting Location: Choose a clean, dry, well-ventilated location that is protected from direct sunlight, extreme temperatures, and moisture. Ensure the battery is securely mounted to prevent movement.
- Wiring:
- Use appropriately sized cables and connectors for your application to minimize voltage drop and heat generation.
- Connect the positive (+) terminal of the battery to the positive (+) terminal of your system/load, and the negative (-) terminal of the battery to the negative (-) terminal of your system/load.
- Ensure all connections are tight and free of corrosion.
- If connecting multiple batteries in series or parallel, refer to the wiring diagrams provided in the full product manual or consult a qualified electrician. The battery supports a maximum of 4 units in series and 4 in parallel.
- Initial Charge: It is recommended to fully charge the battery before its first use. Use a LiFePO4 compatible charger.
5. Operating Instructions
5.1 Charging
- Use a dedicated LiFePO4 battery charger with a voltage range appropriate for 12V lithium batteries.
- The recommended charge current is up to 200A.
- Avoid overcharging or undercharging the battery, as this can reduce its lifespan. The built-in BMS will protect against these conditions.
5.2 Discharging
- The continuous discharge current is 200A. Avoid exceeding this limit for prolonged periods.
- The peak discharge current is 400A for 10 seconds.
- The BMS will disconnect the battery if the voltage drops too low to prevent over-discharge.
5.3 Bluetooth Monitoring
Your EPOCH BATTERIES LiFePO4 battery is equipped with Bluetooth connectivity, allowing you to monitor its status via a dedicated mobile application. Download the official EPOCH BATTERIES app from your device's app store. Follow the in-app instructions to connect and view real-time data such as voltage, current, temperature, and state of charge.
5.4 Self-Heating Function
The integrated self-heating function automatically activates when the battery temperature is below a certain threshold during charging, ensuring optimal charging performance in cold environments. This feature helps protect the battery cells and prolong its lifespan.
6. Maintenance
LiFePO4 batteries require minimal maintenance, but following these guidelines will ensure optimal performance and longevity:
- Regular Inspection: Periodically check the battery terminals for corrosion or loose connections. Clean terminals with a wire brush if necessary.
- Cleaning: Keep the battery surface clean and dry. Use a damp cloth to wipe away dust or dirt. Do not use harsh chemicals.
- Storage: If storing the battery for an extended period, ensure it is charged to approximately 50-70% of its capacity. Store in a cool, dry place, away from direct sunlight and extreme temperatures. Disconnect the battery from all loads and chargers during storage.
- BMS Functionality: The built-in BMS manages cell balancing and protects against overcharge, over-discharge, over-current, and over-temperature conditions. No user intervention is typically required for BMS operation.
7. Troubleshooting
If you encounter issues with your battery, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not charging | Charger not connected, faulty charger, BMS protection activated (over-discharge, over-temperature) | Check charger connection and functionality. Allow battery to cool down if hot. If deeply discharged, a specialized charger may be needed to wake up the BMS. |
| Battery not discharging (no power output) | Loose connections, BMS protection activated (over-discharge, over-current, over-temperature), faulty load | Check all cable connections. Reduce load if over-current. Allow battery to cool down. Verify load functionality. |
| Bluetooth connection issues | App not installed, Bluetooth off on device, battery too far, interference | Ensure app is installed and updated. Turn on Bluetooth on your device. Move closer to the battery. Restart battery (if possible) and device. |
| Battery gets hot during operation | Excessive load, poor ventilation, internal fault | Reduce load. Ensure adequate ventilation around the battery. If overheating persists, disconnect and contact support. |
For issues not listed here or if troubleshooting steps do not resolve the problem, please contact EPOCH BATTERIES customer support.
