5. Installation

Follow these steps for proper installation of your DROK Battery Capacity Volt Monitor:

1. Prepare Mounting Location: Choose a suitable location for the meter. Ensure the installation dimensions (56.5 x 28.5mm) are met for a secure fit. The meter features side mounts for installation.
2. Wiring Connection: Connect the meter to your 12V Iron Phosphate Lithium battery.
   • Connect the Red wire to the positive (+) terminal of the battery.
   • Connect the Black wire to the negative (-) terminal of the battery.
   Ensure all connections are secure and correctly polarized to prevent damage to the device or battery.
3. Secure the Meter: Once wired, insert the meter into the prepared opening and secure it using its side mounts.

6. Operation

The DROK Battery Capacity Volt Monitor is designed for straightforward operation:

1. Power On/Off: The device features a power button (press key) on the front panel. Press this button to turn the display on or off.
2. Display Reading: Once powered on, the color LCD will display the current battery voltage (V) and the remaining battery capacity as a percentage (%). A five-cell battery symbol provides a visual representation of the charge level.

7. Battery Percentage Calibration (LiFePO4)

For optimal accuracy with LiFePO4 batteries, it is recommended to calibrate the battery percentage display. The default settings may not accurately reflect the State of Charge for LiFePO4 chemistry. This procedure allows you to set custom voltage thresholds for 100% (H) and 20% (L) capacity.

Calibration Procedure:

1. Connect Power: Ensure the meter is connected to your battery for power.
2. Turn On: Press the power button to turn the display on.
3. Enter Calibration Mode: Once the voltage reading appears, press and hold the power button for 1-2 seconds.
4. Set 100% Voltage (H): The display will show "12.0v H" (default 100% voltage). Each digit will flash in sequence. To change a flashing digit, press the power button repeatedly until the desired value is reached. For LiFePO4, a common 100% voltage is 13.2V or higher.
5. Set 20% Voltage (L): After setting the "H" value, the display will switch to "10.5v L" (default 20% voltage). Adjust this value similarly. For LiFePO4, a common 20% voltage is 12.0V.
6. Save Settings: To save your new settings, press and hold the power button for 1-2 seconds.
7. Discard Changes: To discard changes, simply wait for the display to time out (approximately 10 seconds) without pressing the button.

Note: Accurate calibration significantly improves the reliability of the percentage display for LiFePO4 batteries. Consult your battery's specifications for precise voltage thresholds.

8. Troubleshooting

• No Display:
  • Check all wiring connections to ensure they are secure and correctly polarized (Red to +, Black to -).
  • Verify that the battery voltage is within the operating range (10-12V).
  • Ensure the power button has been pressed to turn on the display.
• Inaccurate Percentage Reading:
  • Perform the battery percentage calibration procedure as described in Section 7, especially for LiFePO4 batteries.
  • Ensure the meter is correctly configured for a 12V Iron Phosphate Lithium battery.
• Limited Viewing Angle:
  • The LCD display may have a limited optimal viewing angle. Adjust your viewing position or the meter's mounting angle for better visibility.

9. Maintenance

• Cleaning: Use a soft, dry cloth to clean the display and casing. Avoid abrasive cleaners or solvents.
• Environmental Protection: While the panel is splash-proof, avoid submerging the device in water or exposing it to extreme moisture.
• Connection Checks: Periodically inspect wiring connections for corrosion or looseness, especially in marine or RV environments.
