SmallRig NP-F Battery Adapter Plate Lite 3018 is designed to provide greater battery life for your camera rig via a Sony NP-F battery. It provides different output ports, including a 12V DC (5.5/2.5mm) output port and a 7.4V DC (5.5/2.1mm) output port. It features an LED indicator that will turn red when the battery level is less than 30 percent. When the indicator flashes, it means the battery level is less than 10 percent, and you need to replace the battery. The plate features a rubber pad on the bottom for a more stable installation.
