Gaqqee | 1-5pcs Lithium Battery Undervoltage Protection Module 15V Cutoff Over-discharge Protection Board 10A Current 18V 20V 21V

Lithium Battery Undervoltage Protection Module 15V Cutoff Over-discharge Protection Board 10A Current Compatible with 18V 20VFeatures:1. Compatible with 18V/20V/21V devices, protecting lithium batteries from multiple brands2. 15V cutoff prevents over-discharge, significantly extending battery lifespan3. Stable operation with small-to-medium power devices like work lights, fans, and soldering irons4. Simple operation: Connect IN/OUT terminals to activate5. Supports 10A continuous current; adds heat sink for high-current applicationsParameter:1. Low-voltage protection board for lithium batteries, featuring under-voltage and over-discharge protection. Suitable for 18V, 20V, 21V work lights, fans, soldering irons, hot glue guns, etc., preventing battery over-discharge and protecting lithium cells2. Simply connect input voltage to IN and output to OUT for operation. Output shuts off when input voltage drops below 15V to prevent over-discharge3. Discharge protection voltage is 15V (higher than lithium battery charger voltage, ensuring charger recognition)4. Continuous operating current must not exceed 10A. Heat sink installation is mandatory for sustained high-current useImportant Notes:1. This protection board is not suitable for modifying high-power tools such as hammer drills, electric drills, or high-power air compressors.2. When the input voltage drops below 15V, the output shuts off. Even if the input voltage later rises above 15V, output will not resume. Disconnect the input voltage to reset the protection board before output can be restored.Package include:1-5pcs Protection Board
