XH-M603 M632 12V 24V Battery Charging Control Module with Digital Voltage Display

XH-M603 / M632 Battery Charging Control Module – DC 10–30V

Control your battery charging cycle with the XH-M603/M632 battery charging control module. Designed for compatible 12V and 24V battery systems, this compact board monitors voltage and switches the connected charging circuit according to user-set start and stop voltage thresholds.

The onboard digital LED display makes voltage monitoring convenient, while the buttons allow the charging thresholds to be adjusted for a suitable battery setup.

Key Features

• Adjustable charging thresholds: Configure the voltage at which charging starts and stops.

• Digital voltage display: View the monitored voltage on the onboard LED display.

• Automatic relay switching: Connects or disconnects the controlled circuit when the configured voltage threshold is reached.

• Wide module input range: DC 10–30V, according to the published specifications.

• Designed for 12V/24V battery systems: Use only with a compatible battery, charging source, and configuration.

• Compact circuit board: Approximate dimensions of 82 × 58 × 18mm, as reported by matching listings.

• Simple button operation: Set charging thresholds using the onboard controls.

• Battery voltage monitoring and relay-control projects

• Suitable solar-assisted battery charging setups

• DIY power-management systems

• Battery charging automation for compatible lead-acid or other supported battery systems

Important Compatibility and Safety Notes

This module is a charging control switch, not a complete regulated battery charger. It does not replace the correct charger, charge-current limiting, cell balancing, or a chemistry-specific battery management system.

Before use, confirm the battery chemistry, charging voltage, relay contact rating, current requirements, and terminal wiring. Do not connect a battery or power source solely on the basis of the nominal 12V/24V description.
