Anyone using a 2s 7.4v battery on a Pixhawk 450 Helicopter

Thanks in advance for any help
3DR Pixhawk, 450 helicopter, 3800kv motor, Emax digital servos,
Currently I am using 3s 11.1volt lipo batterys on my helicopter. Wanting to know is it possible to use a 2s 7.4v lipo on this helicopter without running the chance of burning up the Pixhawk or other parts and is there a setup process to use 2s if possible? ( I have used 2s lipo on drones, but that is a different animal)
Thanks

William it could probably work. Pay attention to providing proper power for the flight controller, as I noted in this thread on what happened with one of my heli’s.
