4.1. Power and Battery Connections
- Identify the screw terminals on the left side of the module. These are typically labeled for input power and battery connection.
- Connect your DC power source (6-60V) to the appropriate input terminals. Ensure correct polarity.
- Connect the battery to be charged to the designated battery terminals (BT+ and BT-). Observe correct polarity. The module will monitor the voltage of this connected battery.
- The module's output for charging is directly connected to the battery terminals.
4.2. Serial Port Connection (Optional)
For advanced control and data monitoring, the module provides a serial communication interface. Refer to Figure 4.2 for the location of the RX, TX, and GND pins. Connect these to a compatible serial device (e.g., a microcontroller or PC with a USB-to-serial adapter) for custom programming or data logging.
5. Operating Instructions
The XY-L30A module features an LCD display and four control buttons: SET, UP, DOWN, and RUN. These buttons are used to configure the charging parameters.

5.1. LCD Display Overview
The LCD displays the following information:
- Battery Voltage (V): Current voltage of the connected battery.
- Charging Percentage (%): Estimated charge level of the battery.
- Charging Time (HH:MM): If time control is enabled, this shows the elapsed or remaining charging time.
5.2. Basic Operation and Parameter Setting
The module typically operates by setting a lower voltage limit (start charging voltage) and an upper voltage limit (stop charging voltage). When the battery voltage drops below the lower limit, charging begins. When it reaches the upper limit, charging stops.
- Enter Setting Mode: Press the SET button. The display will show the current parameter.
- Navigate Parameters: Use the UP and DOWN buttons to cycle through different adjustable parameters (e.g., start voltage, stop voltage, charging time limit).
- Adjust Value: Once a parameter is selected, press SET again to enter edit mode. Use UP and DOWN to change the value.
- Save and Exit: Press and hold the SET button for a few seconds to save the changes and exit the setting mode.
- Start/Stop Charging: The RUN button typically acts as a manual override or to enable/disable the automatic charging function. Consult the specific firmware documentation for precise functionality.
Note: Specific parameter names and their exact adjustment procedures may vary slightly. Refer to the manufacturer's detailed programming guide if available for advanced configurations.
5.3. Time Control Function
The module supports a charging time limit. This feature prevents overcharging by stopping the charging process after a set duration, even if the target voltage has not been reached. This parameter can be set within the configuration menu using the SET, UP, and DOWN buttons.
6. Maintenance
The XY-L30A module is designed for reliable operation with minimal maintenance. Follow these guidelines to ensure optimal performance and longevity:
- Keep Clean and Dry: Ensure the module is kept in a clean, dry environment, free from dust, moisture, and corrosive substances.
- Check Connections: Periodically inspect all wiring connections to ensure they are secure and free from corrosion. Loose connections can lead to poor performance or damage.
- Avoid Physical Damage: Handle the module with care to prevent physical impact or stress to the components.
- Ventilation: Ensure adequate airflow around the module, especially if operating at higher currents, to prevent overheating.
7. Troubleshooting
If you encounter issues with your XY-L30A module, consider the following troubleshooting steps:
- Module Not Powering On:
- Verify that the input power supply is within the DC 6-60V range.
- Check all power connections for correct polarity and secure contact.
- Battery Not Charging:
- Ensure the battery is correctly connected to the BT+ and BT- terminals with correct polarity.
- Check the set start charging voltage. The battery voltage must be below this threshold for charging to initiate.
- Verify that the RUN button has not disabled the charging function.
- Inspect the battery itself to ensure it is capable of accepting a charge.
- Charging Stops Prematurely:
- Check the set stop charging voltage. Charging will cease once this voltage is reached.
- Review the time control settings. If a charging time limit is set, charging will stop after the elapsed time.
- Ensure the battery is not experiencing an internal fault that causes its voltage to rise rapidly.
- Inaccurate Voltage/Percentage Display:
- Ensure connections are tight and free of resistance.
- Compare the module's reading with a calibrated multimeter to check for significant discrepancies.
If these steps do not resolve the issue, contact the seller or manufacturer for further assistance.
