XH-M603 12V – 24V Battery Charge Controller Protection Module User Guide

🚀 Description

The XH-M603 / HW-632 Battery Charging Control Module is a 12-24V battery charger control switch protection board with an LED voltage display. A DC input voltage source (30V maximum) such as a solar panel, DC power supply, or battery charger is connected to the input, and a lead-acid, lithium-ion, polymer, nickel-cadmium or nickel-metal hydride battery is connected to the output.

This module monitors the battery voltage and connects the charging input to the battery when the battery voltage drops below the “starting voltage” preset level, and disconnects the voltage from the battery when the battery voltage reaches the “stop voltage” preset level.

In addition to regulating the charging voltage from an unregulated source such as a solar panel, this controller will also control the charging cycle, disconnecting the battery charger from the battery when it is fully charged, reducing overheating and degradation of the battery leading to longer battery life.

⚙️ Key Features

• Automatic control to turn the battery charging on and off. Not only saves energy but also extends the battery life and prevents battery overcharge.
• Easy to operate – with the start and stop buttons, you can set the start charging voltage and the stop charging voltage.
• Digital display – easy to read and monitor the charging status.
• After the parameter is set, it will be saved automatically. It is not necessary to reset the parameters after power off.

🔌Specifications

• Mounting holes: 4 x M3 screw holes for easy mounting. The hole diameter is 3mm

🔧 Installation & Operation

1. Connect the rechargeable battery to the module’s battery (BAT) terminals, as shown in the image above, ensuring proper polarity. The LED display will show the battery voltage. Please note that the module draws its support power from the battery for its operation, not from the battery charger.
2. In the normal display mode, pressing and holding the UP/START button will display charging start voltage. You can long press it for around 3 seconds to see a flashing display. Then you can tap the UP and DOWN buttons to set the start voltage value. When the required voltage is set, leave the buttons until the flashing stops and the chosen voltage will be set.
3. While in the normal display mode, pressing and holding the DOWN/STOP button will display charging stop voltage. You can long press it for around 3 seconds to see the flashing display and then tap the UP and DOWN buttons to set the stop voltage value. When set, leave the button until flashing stops and the chosen voltage will be set.
4. Now connect the battery charger to the charger input (IN) terminals of the module, as shown in the image above. Keep in mind that this module is a charge controller, not a full-featured battery charger. It’s important to match your battery charger to the correct voltage and current for the battery you are charging. The controller does not have current limiting. The maximum current should be limited at the power source, if necessary.
5. In power-on state, you can factory reset the module by pressing the UP and DOWN buttons simultaneously for around 3 seconds. It will then show 888 in the LED display, indicating that it has been reset. The default/factory values are 12V (start value) and 14.5V (stop value).
