4. Setup
4.1 Initial Inspection
Upon receiving your battery, inspect it for any visible damage. If damage is found, contact customer support immediately.
4.2 Charging
Before first use, fully charge the battery using a compatible LiFePO4 charger. Ensure the charger's voltage and current settings are appropriate for a 12V LiFePO4 battery.
4.3 Connecting the Battery
- Connect the positive (+) terminal of the battery to the positive terminal of your load/charger.
- Connect the negative (-) terminal of the battery to the negative terminal of your load/charger.
- Ensure all connections are secure and tight to prevent resistance and overheating.
4.4 Parallel and Series Connection
This battery supports up to 4 batteries in parallel and 2 in series (4P2S) for increased capacity and voltage. When connecting multiple batteries:
- Use batteries of the same model, capacity, and age.
- Ensure all batteries are fully charged to the same voltage before connecting.
- Use appropriate cables and fuses for the combined current.
- For parallel connections, connect positive to positive and negative to negative.
- For series connections, connect the positive of one battery to the negative of the next.
4.5 Bluetooth APP Installation
Download the "ECO-WORTHY" APP from your smartphone's app store. Follow the in-app instructions to connect to your battery via Bluetooth for real-time monitoring.

5. Operating Instructions
5.1 Monitoring Battery Status
You can monitor the battery's State of Charge (SOC) and other parameters using two methods:
- Integrated LED Display: The display on the battery provides a quick visual indication of SOC (0-100%) and alerts for high/low temperature, over/under voltage, overcurrent, and BMS faults.
- ECO-WORTHY APP: For detailed real-time data, including voltage, current, capacity, and individual cell information, use the Bluetooth APP.
5.2 Storage Mode
The battery features a storage mode to minimize self-discharge during periods of inactivity, preserving battery life.
- Activation: Press and hold the power button for 3 seconds to activate storage mode.
- Deactivation: Press the power button once to exit storage mode.
