Asked by: Issac
The Nanlite FC Power Controller can be used with 14.4, 14.8, and 26 V batteries as long as you have the proper adapter plate. The Wh is merely the capacity of the battery.

Does this add plus - minus green/magenta to the 500B, or just the 500c?
Asked by: Steven Michael
The Nanlite FC500B Bi-Color LED Spotlight does not have magenta/green adjustment. The Nanlite Forza 500B II Bi-Color LED Monolight has that feature, https://bhpho.to/3OuHw8U. The Nanlite FC Power Controller cannot add features to a light that does not have those features to control.
