XH-M603 battery charging control module with timer and relay

The XH-M603 is an upgraded battery charging control module featuring both voltage-based and timer-based automatic cut-off. It uses a relay to disconnect the charger once the battery reaches the set voltage or the timer expires, preventing overcharging and extending battery life. Ideal for 12V lead-acid and lithium-ion battery systems.

Key Features:

• Dual control: voltage threshold + adjustable timer cut-off
• Relay output for automatic charger disconnection
• Adjustable charge voltage via potentiometer
• Adjustable charging time (timer function)
• LED indicators for power, charging, and full charge status
• Compatible with 12V lead-acid and Li-ion battery systems
• Compact PCB module, easy to integrate into DIY projects

Applications:

• 12V lead-acid battery charging systems
• Solar charge controller projects
• DIY battery management and protection systems
• UPS and backup power projects
• Timed charging applications for embedded systems
