3. Setup and Installation
3.1 Wiring Instructions
Proper wiring is crucial for the correct operation of the battery monitor. The device comes with pre-attached wires for connection.
- Connect the Red wire to the positive (+) terminal of your battery.
- Connect the Black wire to the negative (-) terminal of your battery.
The length of the provided wires is approximately 39.37 inches (1 meter). Ensure secure connections to prevent intermittent readings or damage.

3.2 Initial Configuration
Upon initial power-up or after installation, it is essential to perform a simple setting adjustment according to the instructions. Failure to do so may result in the percentage display consistently showing 100%, regardless of the actual battery capacity.
Refer to the 'Operating Instructions' section for detailed steps on configuring battery type and voltage parameters.

4. Operating Instructions
4.1 Display Modes
The monitor typically displays voltage and battery capacity percentage. A short press of the 'M' key allows you to switch between displaying voltage and temperature (in Celsius).
4.2 Setting Battery Type and Voltage
To ensure accurate readings, configure the monitor for your specific battery type and voltage. The default setting is typically for a 12V lead-acid battery. The exact procedure for entering the settings menu and adjusting parameters will involve pressing and holding specific buttons (e.g., 'M' or power button) for a few seconds until the display changes to a setup mode. Follow the on-screen prompts to select:
- Battery Type: Ternary lithium, Lead-acid, AGM, or LiFePO4.
- Battery Voltage: The nominal voltage of your battery system (e.g., 12V, 24V, 48V).
The monitor features power-off memory, so your settings will be retained even if power is removed.
4.3 Buzzer Alarm Configuration
The monitor allows you to set custom low and high voltage buzzer alarms. When the battery voltage falls below the low threshold or exceeds the high threshold, the buzzer will sound to alert you. Consult the device's on-screen menu for specific steps to adjust these alarm values.
5. Maintenance
The SUPNOVA Battery Monitor is designed for durability and requires minimal maintenance.
- Cleaning: Use a soft, dry cloth to clean the display and casing. Avoid abrasive cleaners or solvents.
- Environment: This device is not waterproof and is intended for indoor use or protected environments. Avoid exposure to moisture, extreme temperatures, or direct sunlight for prolonged periods.
- Connections: Periodically check wiring connections to ensure they remain secure and free from corrosion.
The monitor is designed not to generate excessive heat even during prolonged use at high voltages (under 100V).
6. Troubleshooting
6.1 Percentage Always Displays 100%
This is a common issue if the initial configuration for battery type and voltage is not performed. Refer to Section 4.2 'Setting Battery Type and Voltage' to correctly set up your monitor. The device needs to know the battery's nominal voltage and chemistry to accurately calculate capacity.
6.2 Inaccurate Readings
- Incorrect Settings: Double-check that the battery type and voltage settings match your actual battery.
- Loose Connections: Ensure all wiring connections are tight and free from corrosion.
- Voltage Drop Under Load: It is normal for the displayed percentage to drop under heavy load and recover when the load is removed. This reflects the battery's actual behavior.
6.3 Device Not Responding / Bricked
The monitor may have a calibration menu (e.g., Menu 5) that should only be accessed and adjusted by qualified personnel or if specifically instructed. Entering incorrect values or confirming calibration with a non-standard voltage source can potentially render the device inoperable. Avoid making adjustments in calibration menus unless you are certain of the procedure and requirements.
If the device becomes unresponsive, disconnect power for a few minutes and then reconnect. If the issue persists, contact customer support.
6.4 Settings Not Visible After Re-entering Menu
Some menu interfaces may not display the currently saved settings when you re-enter them. It is advisable to document your chosen settings (battery type, voltage, alarm thresholds) after initial configuration for future reference.
