2. Product Features
- LED Battery Indicator: Displays remaining battery power using 10 LED bars. The display includes 1 red, 2 yellow, and 7 green bars, with each bar representing 10% of battery power.
- Battery State of Charge & Discharge: Shows battery charge status by LED bars stepping up and discharge status by LED bars stepping down. Features a charge delay time of 200 seconds and a discharge delay time of 155 seconds.
- Low Battery Reminder: Alerts the user when battery capacity is low. When capacity is ≤20%, one LED bar flashes. When capacity is ≤10%, two bars flash alternately.
- Water Resistance: Favorable water resistance up to IP65, ensuring durability in various environments.
- Easy Installation: Designed for snap-in panel mounting with a cut-out size of 37.00mm x 25.00mm (1.46 inches x 0.98 inch). Supports direct power connection and key switch power connection.

4. Installation
4.1 Panel Cut-out and Mounting
The RL-BI003 is designed for snap-in panel mounting. Ensure you have a panel cut-out with the following dimensions:
- Width: 37.00mm (1.46 inches)
- Height: 25.00mm (0.98 inch)
Once the cut-out is prepared, simply push the indicator into the opening until it snaps securely into place.

4.2 Power Connection
There are two primary methods for connecting power to the RL-BI003:
- Direct Power Connection: Connect the positive (+) terminal of the indicator directly to the positive terminal of your 12V/24V lead-acid battery. Connect the negative (-) terminal of the indicator to the negative terminal of the battery.
- Key Switch Power Connection: For applications where the indicator should only be active when the vehicle or equipment is on, connect the positive (+) terminal of the indicator to the positive terminal of your 12V/24V lead-acid battery. Connect the negative (-) terminal of the indicator to the negative terminal of the battery. Additionally, link the 'C' pole (common) of the indicator to the positive (+) side of your key switch. This ensures the indicator receives power only when the key switch is engaged.
Important Note: For normal battery power display, ensure the 'C' pole is connected to the positive (+) power source.

5. Operation
5.1 Battery Charge and Discharge Display
The RL-BI003 uses a 10-segment LED bar graph to visually represent battery capacity. Each illuminated bar indicates 10% of the battery's charge.
- Charging: As the battery charges, the LED bars will progressively light up, stepping upwards to indicate increasing capacity. There is a 200-second delay before the display updates during charging.
- Discharging: As the battery discharges, the LED bars will progressively turn off, stepping downwards to indicate decreasing capacity. There is a 155-second delay before the display updates during discharging.

5.2 Low Battery Reminder
The indicator provides visual alerts when the battery level reaches critical thresholds:
- When battery capacity is at or below 20%, the first LED bar will flash to remind you to charge the battery.
- When battery capacity is at or below 10%, the first two LED bars will flash alternately, indicating a very low battery state that requires immediate charging.

7. Maintenance
The Runleader RL-BI003 is designed for minimal maintenance. To ensure optimal performance and longevity:
- Keep the indicator clean and free from excessive dirt or debris.
- Periodically check wiring connections to ensure they remain secure and free from corrosion.
- Avoid exposing the device to extreme temperatures beyond its operational range.
- While the device is IP65 water-resistant, avoid prolonged submersion or high-pressure water jets.
8. Troubleshooting
If you encounter issues with your Runleader RL-BI003, consider the following:
- Indicator not displaying correctly or showing incorrect readings:
- Verify that the 'C' pole is correctly connected to the positive (+) power source, especially if using a key switch connection. Incorrect wiring of the 'C' pole can lead to false or no readings.
- Ensure the positive and negative connections to the battery are secure and correctly polarized.
- Confirm that the battery voltage is within the 12V to 24V range for lead-acid batteries.
- Indicator does not reset after charging:
- Some systems may require a power cycle to refresh the indicator's reading after a full charge. This might involve briefly disconnecting and reconnecting the ground wire, or cycling a master switch if available.
- No display:
- Check all power connections for continuity and ensure there is voltage present at the indicator's terminals.
- Confirm the battery itself has sufficient charge to power the indicator.
If troubleshooting steps do not resolve the issue, please contact customer support.
