5. Setup and Installation
5.1 Unpacking and Inspection
Carefully remove the battery and accessories from the packaging. Inspect all components for any signs of damage. If any damage is found, contact customer support immediately.
5.2 Mounting the Battery
The LOSSIGY LiFePO4 battery is significantly lighter than traditional lead-acid batteries of similar capacity, making installation easier. Choose a secure, well-ventilated location for mounting the battery. Ensure the battery is firmly secured to prevent movement during operation.
5.3 Electrical Connections
- Ensure all power to the system is turned off before making any connections.
- Connect the positive (+) terminal of the battery to the positive (+) terminal of your golf cart, trolling motor, or marine system.
- Connect the negative (-) terminal of the battery to the negative (-) terminal of your system.
- Use appropriate gauge cables for your application to handle the current.
- Parallel Connection: If connecting multiple batteries for increased capacity, ensure they are connected in parallel only. Connect positive to positive and negative to negative. Do not exceed 4 batteries in parallel. Do not connect batteries in series.

6. Operating the Battery
6.1 Initial Charge
It is recommended to fully charge the battery before its first use.
6.2 Charging Procedure
- Connect the 43.8V 25A smart charger to the battery's charging port.
- Plug the charger into a standard AC power outlet.
- The charger will indicate the charging status. A full charge from 0% to 100% typically takes approximately 4 hours.
- Once charging is complete, disconnect the charger from the power outlet, then from the battery.
6.3 Battery Monitoring
The LOSSIGY battery offers two ways to monitor its status:
- Bluetooth App: Download the LOSSIGY app on your smartphone. After successfully connecting via Bluetooth, you can view real-time battery data, including state of charge, voltage, current, and temperature.
- Touch Screen Monitor: The included touch screen monitor can be installed to display real-time battery information directly on your golf cart or vehicle dashboard.

7. Maintenance
Proper maintenance ensures the longevity and performance of your LiFePO4 battery.
- Regular Inspection: Periodically check the battery terminals for corrosion and ensure all connections are tight.
- Cleaning: Keep the battery clean and free of dirt and debris. Use a dry cloth to wipe the battery surface. Do not use solvents or 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. Recharge every 3-6 months to prevent deep discharge.
- Temperature: The optimal operating temperature range is between -20°C to 60°C (-4°F to 140°F). The BMS provides protection against extreme high/low temperatures.
8. Troubleshooting
If you encounter issues with your LOSSIGY battery, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not charging | Charger not connected, faulty charger, BMS protection activated. | Ensure charger is properly connected and plugged in. Check charger indicator lights. If BMS protection is active (e.g., due to over-discharge), try reconnecting the charger. Contact support if issue persists. |
| No power output from battery | Loose connections, BMS protection activated (over-discharge, overcurrent, short circuit). | Check all cable connections for tightness. Use the monitoring app/display to check battery status. If BMS has tripped, remove the load and allow the battery to reset or charge. |
| Bluetooth app not connecting | Bluetooth disabled on phone, battery out of range, app issue. | Ensure Bluetooth is enabled on your device and you are within range of the battery. Restart the app or your phone. |
| Reduced run time | Battery not fully charged, aging battery, high power draw. | Ensure battery is fully charged before use. Monitor power consumption. While the battery has a long cycle life, capacity can gradually decrease over many years of heavy use. |
For issues not covered here, or if troubleshooting steps do not resolve the problem, please contact LOSSIGY customer support.
