Features: Specially designed for high current applications to meet the needs of power equipment. Advanced capacitive balancing technology is adopted, which effectively reduces the calorific value, is more energy efficient than the traditional balancing, and prolongs the service life of the battery. Built in acquisition circuit can monitoring each battery cell in real time, realize accurate balanced control and ensuring the safety and stability of the battery pack. It supports 4S/6S/8S different battery configurations, flexibly adapts to the needs of different application scenarios, and can be widely used in power tools, electric vehicles, energy storage and other fields. Integrate multiple protective mechanisms such as overvoltage, undervoltage and short circuit to ensuring the safe operational of the battery pack in an all-round way and prevent damage caused by abnormal conditions.
