4. Setup and Installation
Proper installation is crucial for the performance and safety of your battery. Follow these general guidelines:
- Unpacking: Carefully remove the battery from its packaging. Inspect for any signs of damage during transit.
- Placement: Install the battery in a clean, dry, and well-ventilated area. Ensure it is secured to prevent movement or tipping. Avoid locations with direct sunlight, high temperatures, or near flammable materials.
- Wiring: Use appropriate gauge cables for your application to minimize voltage drop and heat generation. Connect the positive (+) terminal of the battery to the positive terminal of your load/charger, and the negative (-) terminal to the negative terminal. Ensure all connections are tight and secure.
- Series and Parallel Connections: If connecting multiple batteries, ensure they are of the same voltage and capacity. Follow the manufacturer's guidelines for series (up to 2 in series) and parallel (up to 4 in parallel) configurations. Incorrect wiring can damage the batteries and connected equipment.
- Initial Charge: It is recommended to fully charge the battery before its first use.

7. Troubleshooting
This section provides guidance for common issues. For more complex problems, consult the ECO-WORTHY app or contact customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not charging | Low temperature (below -7°C), charger fault, BMS protection activated. | Move battery to a warmer environment, check charger connection and functionality, check app for BMS fault codes. |
| Battery not discharging | Very low temperature (below -20°C), over-discharge protection, BMS fault. | Move battery to a warmer environment, charge the battery if deeply discharged, check app for BMS fault codes. |
| Audible alarm sounds | Over-voltage, under-voltage, over-current, high temperature, or BMS fault detected. | Check the LED indicator panel or ECO-WORTHY app for the specific fault. Address the underlying issue (e.g., reduce load, check charging voltage). The alarm can be silenced via the app. |
| Bluetooth connection issues | Out of range, Bluetooth disabled on phone, interference. | Ensure phone is within 25m of the battery, enable Bluetooth, minimize obstructions, restart app/phone. |
