Battery Voltage Balancer 4S-24S Li Ion Lifepo4 10A Active Balancer Electric Vehicle RV Energy Storage Lithium Battery 4S 8S 16S 20S BMS Equalizer (Color : For 3.2V 3.7V 4S-8S, Size : 10A Balancer)

Made of material, durable and stable, has a long service life. Simple streamline design appearance, conveneint to use. It is used to balance the voltage and over-charging, to extend your battery life time. Wide applicable range: for solar energy, car vehicle industry, battery pack, electric vehicles, telecom industry and so on. When two or more in-series connected batteries are in charging/discharging/free status. The battery voltages maybe become different. One battery voltage is high and one is low. It will shunt current from one battery (the higher voltage one) to the other battery (the lower voltage one). Until their battery voltage almost becomes same. This will improve battery's performance and extent
