15V 10A Battery Protection Board Low Voltage/Over-Discharge Protection for 18/20/21V Battery Over-Discharge Protection Board

High-concerned chemical : none Charging Current : 15A Usage Scenario : Energy Storage BMS Certification : CE Balance Function : Passive Balanced BMS Handware or Smart : Handware BMS Charge and Discharge Port : Common Port BMS Type : LI-ION Battery BMS Origin : Mainland China Brand Name : occkic Function : Overcharge Protection,Over Discharge Protection

Features: 1. Compatible with 18V/20V/21V devices, protecting lithium batteries from multiple s 2. 15V cutoff prevents over-discharge, significantly extending battery lifespan 3. Stable operation with small-to-medium power devices like work lights, fans, and soldering irons 4. Simple operation: Connect IN/OUT terminals to activate 5. Supports 10A continuous current; adds heat sink for high-current applications Parameter: 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 cells 2. Simply connect input voltage to IN and output to OUT for operation. Output shuts off when input voltage drops below 15V to prevent over-discharge 3. 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 use Important 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: Protection Board*1
