Hello, I do not know how to properly power a AR7610 Spektrum receiver directly. How do i make a wire to plug into the 3 pin port? What port do i plug it into? What battery would you recommend? I would like to use 1 battery to power a receiver, full frame tarot 5d2 3 axis gimbal, and ZYX 13 gimbal controller. If you were powering all of these devices off one battery, what pack would you use? please advise! Thank you
