Question
How to power the camera?

So I got a cheap setup, but it works. The camera and transmitter run on a 9v battery. But it uses alot of power and the battery doesn't last long. I run my car on 4s lipo, and was wondering if there was some BEC or voltage regulator that could be wired into the ESC battery wires and have a 9v output for the camera, so it could run on the large battery and then I won't have to deal with two batteries.

Anyone know of something that can supply 9v to the camera?

Thanks, Zane

9V? That's strange. Maybe you could link us to the exact cam/tx/rx set you have?

Strange, huh? I don't have a link. It is some cheap off brand system. I only use it for rock crawling around our yard with the Summit. And i just looked at the manual and you can also use it with 8 volts

That's a good question. UBECs almost always deliver between 5 and 6 volts. Sometimes it's good to have other voltages for your example or for cases when you want to conserve energy by powering a camera or transmitter at less 12V. I wonder if existing UBEC's can easily be modified by replacing a single component as I've seen switching DC-DC regulator components for various voltages for sale already.

Found this. Apparently Castle's external BEC's can provide up to 9 volts. Perfect. And I already have a Castle link USB kit. Now where is a good place to get one?

Boom. Turn the screw until you get to 9 volts. Easy mode.

The CC BEC looks promising. Based solely on my experiences in how much attention Chinese give to producing quality products, I would trust the CC BEC more than the BevRC regulator, as I assume that there is absolutely nothing done to suppress RF noise in the latter. I can't see if the CC BEC has some sort of metal shielding below the heat shrink covering though.

I think I will go with the castle one, just because if it malfunctions it will fry my camera, so I want the tried and trusted brand (I love castle stuff )
