4S Charging Drill Protection Board PCB Circuit Board Electric tool

Label:Yes Charging voltage: 16.8V Operating Temperature: -40°-85° RH≤75% Overcurrent protection current: 40A-50A Name:Protection Board Continuous discharge current: 0-30A Store Temperature: -40°-125° RH≤75% Overcharge Protection Delay:1S Length*Width:34.8*34.4mm(1.37*1.35in)

The protection board is for 4 series Li-ion batteries, mainly used for electric power tools. It uses special IC for 4S lithium batteries as 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 to your batteries.
