led power

I have the flite test 80 amp Esc and it has that little connecter that I heard was used for LED lights and I just wanted to know how that works and what lights would work on it. I’m planning on putting it on a 7.5 foot Rc plane I built and wanted to make sure the lights could have extensions to...

I have found a plug that is 3s to 4 plug for my leds. I am looking for a 3s to 9 JST plug for my leds. I am going to use a smaller 3s battery to power my lights so I can use my battery monitor on the flight battery. Does anyone know of a connector 3s to 9 JST?
