Tomshine 2A BMS Active Balancer Lithium Battery Energy Transfer Balance Module 3.7V 3.2V Battery Packs Balance Board

This tool can intelligent detection of the unbalance difference between adjacent battery packs can realize the transfer of high voltage to low voltage so as to achieve the voltage balance between battery packs. Features: Stable Heat Dissipation: The open design can effectively dissipate heat and it will not overheat when working effectively prolonging its service time. It can automatically detect the unbalanced voltage value between adjacent battery strings. When the pressure difference value is≥0.1 it has three modes of continuous work discontinuous work and stop work and can balance the difference value is ≤0.03V. The surface of the circuit board has been painted which can realize waterproof dustproof and -leakage and improve its safety. This tool is applicable to 3.7V battery packs and 3.2V lithium battery packs has wide applications. K1 means keep active balance on the middle means when the battery voltage is lower than 3V turn off active balancing and sleep K2 means turn off active balance and in to sleep. Specifications: Material: Printed circuit board Type: 4S 8S (optional) Balance current:
