Description
Features: The protection board is for 5 series Li-ion batteries, mainly used for electric power tools. It uses a special IC for 5S lithium batteries as a processor to detect real-time voltage, charge and discharge current and ambient temperature of each battery. Stable various protective functions for charging and discharging, such as overcharge protection, over-discharge protection, and short circuit protection. Low power consumption, the working current is about 25uA and quiescent current is about 6uA. Choosing the correct protection board and applying it appropriately is vital to the longevity of your batteries. Specifications: Charge Voltage: 19/21V Single Cell Charge Voltage: 3.8/4.25V Continuous Discharge Current: 8-20A Overcharge Single Cell Detection Voltage: 3.85-4.25V Overcharge Protection Delay: 1S Overcharge Single Cell Recovery Voltage: 3.75-4.13V Overcharge Protection Release Delay: 1mS Over-discharge Single Cell Detection Voltage: 2-2.8V Over-discharge Protection Delay: 1S Over-discharge Single Cell Recovery Voltage: 2.5-3.0V Over-discharge Protection Release Delay: 10020mS Over-current Detection Voltage: 0.1-0.4V Over-current Detection Current: 305A Over-current Detection Delay: 1S Short Circuit Protection Support: Yes Short Circuit Detection Delay: 250uS Short Circuit Release Delay: 1S Short Circuit Detection Voltage: 0.8V Recovery State: Auto after Disconnect Load Over Temperature Protection: 705 Recovery Temperature: 555 Working State: 25uA (25) Stand-by State: 6uA(25) Discharge Main Circuit Internal Resistance:305m Operating Temperature: -40-85 RH75% Store Temperature: -40-125 RH75% Size Length x Width: 45x40mm/1.77*1.57" Package includes: 1 x Battery Charger Protection Board Note: Please allow 1-3mm error due to manual measurement. pls make sure you do not mind before you bid Due to the difference between different monitors, the picture may not reflect the actual color of the item.
