6. Operating Instructions
6.1 SOC LED Display and Status Indicators
The battery features an integrated LED display on top. Press the 'on/off' button to activate the display. It shows the State of Charge (SOC) in 25% increments (0%, 25%, 50%, 75%, 100%).
Figure 3: Smart LED Indicators on the battery, showing SOC light and Abnormal light for quick status checks.
6.2 Abnormal Status Indicator
The LED display also includes indicators for abnormal conditions such as High Temp, Low Temp, Over Voltage Protection (OVP), Under Voltage Protection (UVP), Over Current Protection (OCP), and BMS Fault. These lights help in quick troubleshooting.

6.3 Buzzer Alarm
If any abnormal conditions arise, the built-in buzzer will alert you. The buzzer alarm provides a periodic sound (8 seconds on, 2 seconds off) and can be turned off through the app or by pressing the 'on/off' button on the battery.
6.4 Smart App Monitoring
The ECO-WORTHY Smart App allows you to monitor various parameters in real-time, including voltage, current, power, and battery status. You can also activate 'Storage Mode' via the app to reduce the battery's self-consumption during long periods of inactivity.
6.5 Low-Temperature Protection
The integrated BMS prevents charging below -7°C (19.4°F) to protect the cells from damage and ensures discharging stops below -4°F. Charging resumes when the temperature is above 0°C (32°F).

7. Maintenance
Proper maintenance ensures the longevity and performance of your battery.
- Regular Charging: If the battery is not used for a long time, it is recommended to charge it to 50% every 3 months.
- Clean Terminals: Keep battery terminals clean and free of corrosion.
- Storage: Store the battery in a cool, dry place away from direct sunlight and extreme temperatures.
- Anti-Swelling Fixture: The internal anti-swelling fixture helps maintain cell integrity by providing stable inward force, preventing expansion due to overcharging, aging, or high temperatures. This contributes to a longer cycle life and improved performance.
8. Troubleshooting
If you encounter issues with your ECO-WORTHY battery, refer to the following common troubleshooting steps:
- Battery Not Charging: Ensure the charger is a compatible LiFePO4 charger with an activation function. Check all cable connections for tightness and correct polarity. Verify the battery temperature is above 0°C (32°F).
- Buzzer Alarm Sounds: Check the LED indicators on the battery or the app for specific fault codes (High Temp, Low Temp, OVP, UVP, OCP, BMS Fault). Address the underlying issue based on the indicator. The buzzer can be turned off via the app or the battery's 'on/off' button.
- Bluetooth Connectivity Issues: Ensure Bluetooth is enabled on your smartphone and the battery. If the Bluetooth module powers off after 3 minutes of inactivity, press the 'on/off' button on the battery to reactivate it. Try restarting the app or your phone.
- Inaccurate App Readings: If the app shows 0% charge or 0 amps despite the battery being charged/discharging, try reconnecting the Bluetooth. Ensure the app is updated to the latest version.
- Overcurrent Protection (OCP) Triggered: If the battery stops providing power under heavy load, the BMS's OCP may have activated. Reduce the load on the battery. The battery will automatically reset once the load is within safe limits.
