Operating Instructions
Your LOSSIGY lithium battery is designed for reliable performance. Once installed, operate your golf cart as usual. The integrated Bluetooth BMS allows for convenient monitoring of battery status via a mobile application.
Bluetooth Monitoring
- Download the official LOSSIGY BMS app from your smartphone's app store.
- Enable Bluetooth on your smartphone and open the app.
- The app will detect your battery. Follow the on-screen instructions to connect.
- Once connected, you can monitor real-time battery voltage, current, temperature, state of charge, and other vital parameters.
Charging
Use a compatible lithium battery charger designed for 36V LiFePO4 batteries. The recommended charging current is 20A, with a charge voltage range of 42.6V-43.8V.
- Connect the charger to the battery's charging port.
- Plug the charger into a standard AC power outlet.
- Monitor the charging process via the BMS app.
- Disconnect the charger once the battery is fully charged (Full Charge Voltage Range: 40.2V-41.4V).
- Charging time is significantly reduced compared to lead-acid batteries, typically taking only a few hours.
Maintenance
LOSSIGY lithium batteries require minimal maintenance compared to lead-acid batteries.
- Regular Inspection: Periodically check battery terminals for cleanliness and tightness. Ensure there are no loose connections.
- Cleaning: Keep the battery surface clean and dry. Use a soft, damp cloth to wipe away any dust or dirt. Do not use harsh chemicals.
- Storage: If storing the battery for an extended period, ensure it is charged to approximately 50% state of charge. Store in a cool, dry place within the recommended storage temperature range (10°F - 122°F).
- Avoid Deep Discharge: While the BMS protects against deep discharge, it is good practice to recharge the battery before it reaches extremely low levels to maximize lifespan.
Troubleshooting
If you encounter issues with your LOSSIGY battery, refer to the following common troubleshooting tips:
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not charging | Charger not connected properly, charger malfunction, battery BMS protection activated. | Check all connections. Ensure the charger is functioning. If BMS protection is active (check app), disconnect and reconnect the charger to reset. |
| Low power output | Low state of charge, loose connections, motor/controller issue. | Check battery charge level via app and recharge if necessary. Inspect all cable connections for tightness. Consult a golf cart technician if the issue persists. |
| Bluetooth connection issues | Bluetooth disabled on phone, app not updated, interference. | Ensure Bluetooth is enabled. Update the app to the latest version. Move closer to the battery to reduce interference. Restart phone and app. |
| Battery overheating | Overload, high ambient temperature, internal fault. | Immediately cease operation and allow the battery to cool down. Reduce load. If overheating persists, contact customer support. |
