The Nanlite FC PowerController is an optional accessory for the FC-300B, FC-500B, and FC-500C LED spotlights that lets you use them on battery power. It features two V-Mount battery plates for 14.4-14.8V or 26V V-Mount batteries (batteries sold separately). It has 2 knobs, 2 buttons, and a 2-inch screen for controlling the connected FC-Series light. You can mount the light high up on a stand and use the manual controls on the FC PowerController closer to you on the ground.

You can connect the FC PowerController to an AC outlet and use it to control the connected light when batteries are not being used. In addition, when connected to a standard AC outlet, the FC PowerController will charge attached 14.4-14.8V and 26V V-Mount batteries. It can be hung on a light stand with a built-in strap, and it also has a mounting plate on the back for attaching to stands with the separately available ASCPQRFZ Super Clamp.
