Features: The protection board is for 5 series Li-ion batteries, mainly used for electric power tools. It uses special IC for 5S 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 vital to the longevity your batteries.
