12V–36V Battery Discharge Protection Module – Car, Solar Panels, and Batteries

The protection module prevents deep battery discharge, extending the lifespan of car batteries or solar batteries.

The device detects the minimum voltage and automatically disconnects the load, preventing battery damage. Once the optimal voltage is reached, power is automatically restored. It is ideal for 12V, 24V, and 36V systems.

Main Benefits:

• Automatic protection against complete battery discharge.
• Auto Power-Off and Auto Reconnect at optimal voltage.
• Reduces the risk of damage to car or solar batteries.
• Compatible with motors, LED lights, controllers, and other DC devices.

Usage Instructions:

• Connect the battery to the VIN terminal (12V–36V DC).
• Connect the load (motor, light, etc.) to VOUT.
• Press and hold the left button to set the shutdown voltage (e.g., 12V).
• Press and hold the right button to set the voltage difference for reactivation (e.g., 1V).
• The relay will stop power when the voltage drops below the threshold and will automatically resume when the voltage returns to the higher level.
