5. Setup Instructions
Follow these steps for safe and correct installation of your battery.
- Unpacking: Carefully remove the battery and charger from their packaging. Inspect for any visible damage.
- Initial Charge: Before first use, fully charge the battery using the provided 25A LiFePO4 charger. Connect the charger to the battery's charging port, then plug the charger into a suitable AC power outlet. The charger indicator will show charging status.
- Mounting: Securely mount the battery in a well-ventilated area, away from direct sunlight, heat sources, and moisture. Ensure the mounting location can support the battery's weight (approximately 43 kg / 94.8 lbs).
- Wiring:
- Ensure all power to the golf cart or application is OFF before connecting.
- Connect the positive (+) terminal of the battery to the positive (+) terminal of your 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. The battery uses removable M8 stud terminals.
- Tighten all connections securely to prevent loose contacts and arcing.
- Parallel Connection (Optional): Up to 4 batteries can be connected in parallel to increase total capacity. When connecting in parallel, ensure all batteries are at a similar state of charge before connecting. Connect positive to positive and negative to negative terminals across all batteries. Consult a qualified technician if unsure.
6. Operating Instructions
Once installed, the battery is ready for use. Monitor its status using the integrated LCD or Bluetooth app.
- Powering On/Off: The battery typically powers on automatically when connected to a load. Some models may have a power button; refer to specific product labeling if present.
- LCD Monitoring: The integrated HD LCD screen provides real-time information such as voltage, current, temperature, and state of charge. Refer to the screen interface for details.
- Bluetooth Monitoring:
- Download the LOSSIGY battery monitoring app from your smartphone's app store.

- Storage: If storing the battery for an extended period, charge it to approximately 50-70% of its capacity. Store in a cool, dry place with temperatures between 10°F and 122°F (-12°C and 50°C). Recharge every 3-6 months during storage to prevent deep discharge.
- Temperature Management: Operate and store the battery within the specified temperature ranges to prevent damage and ensure optimal performance.
8. Troubleshooting
Refer to this section for common issues and their solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not charging | Charger not connected, faulty charger, battery BMS protection activated (over-discharge) | Ensure charger is properly connected and plugged in. Check charger indicator light. If battery is deeply discharged, it may require a specific recovery procedure or professional assistance. |
