Correct. The CF 9 has a voltage regulator attached to the main LED pads (see manual). Since you only have one LED, you attach it to those pads.

@RavenXP, just because it’s “capable” doesn’t mean it actually does. Also, he says he has a 7.4V power source, and those tend not to have a large amperage output.
