How to Power Lightbridge 2 + A2 FC without gimbal

The DJI Lightbridge 2 is a great piece of technology, but if you are flying your UAV without a gimbal and are using the A2 flight controller there is no way to power the air unit unless you use a separate battery. I wanted to use my existing on board 6S battery to power the unit. The lightbridge 2 only takes 9-12 volts so if I just connected my 6S battery it would fry the unit. by using a voltage regulator we can step down the voltage to the appropriate amount for the air unit.

Sorry for crappy camera work, audio, and the like, but hopefully this video helps somebody.

Parts needed:
1. Lightbridge 2
2. Battery (mine is 22.2V 6S Lipo)
3. Lightbridge gimbal cable
4. Multimeter for testing voltage
6. XT60 Male end connector.
7. Soldering iron and solder

Thank you for the detailed tutorial, Jon! It fixes exactly the issue I'm having ;)

Thanks for the detailed modification. I’m sure this technique can be adapted to other systems requiring a voltage regulator.

Yes! It was very helpful! Thanks so much!

Great video, I just took q+the pwr cable from the AV cable and replace it in the gimbal connector, this way I dont damage the cable, next week I will mount the system in place and see if I need to also add the ground cable, but since I have a common ground in the comlete system I sont think that it is needed

I can´t start the motors using LB2 transmitter. I have setup everything on DJI A2 Assistant but no luck! Any tip?

Did you ever figure out why the go home button didn't work?
