Protection Board Circuit Board Electric Power Tools Accessories

Features: The for Protection board is for 5 series Li- for ion batteries, mainly used for electric power tools. It uses special IC for 5S / batteries as processor to detect real-time voltage, charge and discharge for current and ambient temperature of each /. Stable various protective functions for charging and discharging, such as overcharge for Protection, over-discharge for Protection and short circuit for Protection. Low power consumption,the working for current is about 25uA and quiescent for current is about 6uA. Choosing the correct for Protection board and applying it appropriately is for vital to the longevity your batteries.
