The ECO-WORTHY Battery Monitor is a professional coulomb meter designed to measure battery status, including voltage, amperage, power, real-time capacity, and remaining use time. It features two-direction current detection and auto-memory for capacity values.
- Wiring: All wires from the battery's positive or negative pole must pass through the sensor ring.
- Auto-mode: Recommended for most users. Requires wiring and a full discharge/charge cycle to calibrate.
- Manual-mode: For professionals requiring high accuracy; allows manual setting of battery capacity and full capacity voltage.
Wiring and Installation
To ensure accurate readings, the monitor must be installed correctly:
- Thread all wires from the battery's positive or negative pole through the sensor ring.
- Check the amperage on the monitor. It should be positive when charging and negative when discharging.
- If the monitor shows the opposite, turn the sensor ring front side back.
- Ensure both charge and discharge circuits go through the sensor.
Operations
Auto-mode (Suggested)
- Wire the sensor as described above.
- Discharge the battery until empty.
- Press the ▼ button for 3 seconds to zero the capacity.
- Charge the battery until full. The capacity should read 100%. If not, press the ▲ button for 3 seconds while the charger is attached to fill the capacity.
Manual-mode (Professional)
- Wire the sensor as described above.
- Press the ⚙ button for 3 seconds to enter the setting menu.
- Use ▼ or ▲ to navigate to 11CA (Battery Actual Capacity) and 12FV (Full Capacity Voltage).
- Press ⚙ to select, adjust values with ▼ or ▲, and press ⚙ to confirm.
- Charge the battery to full to complete the setup.
Settings Menu
There are 14 setting objects available. Access the menu by holding the ⚙ button for 3 seconds.
- 01ZV (Zero Capacity Voltage): Sets capacity to 0% when voltage is below this value.
- 02OV (Over Voltage Alarm): Triggers alarm when voltage exceeds this value.
- 03OC (Over Amperage Alarm): Triggers alarm when amperage exceeds this value.
- 04LV (Low Voltage Alarm): Triggers alarm when voltage drops below this value.
- 05LB (Low Capacity Alarm): Triggers alarm when capacity drops below this value.
- 06HT (High Temperature Alarm): Triggers alarm when temperature exceeds this value.
- 07VC/08CC/09CZ/10TC: Fine-tuning settings for voltage, amperage, and temperature.
- 11CA: Battery's actual capacity.
- 12FV: Full capacity voltage (for manual mode).
- 13LK: Menu lock (LOCK/UNLOCK).
- 14DF: Reset to default settings.
Precautions
- Do not expose the monitor to strong sunlight or extreme environments below -10°C (14°F).
- The monitor and sensor ring are strictly matched; do not change them.
- The monitor is covered by a 1-year warranty.

Practical help
Common problems
Capacity drops when discharging but does not rise when charging.
Ensure the main positive or negative wire is threaded through the sensor ring. Both charge and discharge circuits must pass through it.
Amperage is not 0 when the battery is empty.
Adjust the amperage manually using setting '09CZ' in the setting menu.
Monitor shows negative current when charging.
The sensor is wired in the wrong direction. Turn the sensor ring front side back.
Before use
- Thread all wires from the battery pole through the sensor ring.
- Verify positive current when charging and negative when discharging.
- Discharge battery to empty.
- Zero the capacity by holding the ▼ button for 3 seconds.
- Charge battery to full.
