The Efest LUC V6 6-Bay MultiCharger is an updated version for 2018, and it's set to revolutionize the world of smart chargers and batteries through its new LCD indicator screen. This MultiCharger has six bays, charging up to six batteries simultaneously. It is a great advantage when you suddenly find that several of your rechargeable batteries are low on power. You need to do it quickly and efficiently to revitalize them. The springs and tabs that hold the batteries in place in their slots are built from stainless steel and are guaranteed to not crack, split, or fracture even after heavy and frequent use. Every slot is equipped with its own screen that oversees each battery's charge. The Efest smart charger even displays each battery's individual voltage and charging current. To use the device, insert a rechargeable cell into a bay. The charger is so smart it can detect the chemistry and voltage and select the appropriate charging method.
