4 NP-F770 rechargeable batteries and a convenient 4-slot charger in one kit.
The ProMaster 4731 Quad Charger Kit is an especially convenient way to power lights without the hassle of power cords laying all over the floor or when a wall outlet is not available. Many LED light panels require two NP-F type batteries, making this Quad Charger Kit the perfect companion for a 2-light kit.
The quad charger has a convenient LCD screen to display approximate charge levels for each battery. It will automatically recognize an NP-F type battery inserted into any one of its 4 slots. It is also compatible with other brands and capacities of NP-F type batteries. This unit will fully charge 1 or 2 of the included NP-F770 batteries from 0 to 100% in approximately 3 hours. It will fully charge 3 or 4 of the included batteries in approximately 5 1/2 hours.
The 4 included batteries are high capacity 4,400 mAh units which use the best quality li-ion cells available. Unlike many other brands, these ProMaster batteries truly perform at or above their rated capacities.
