Could some one help me identify the cable I would need to power a c300mkii from the movi pro batteries? I didn't see it as an option in the accessory list. Also, what cable could I use to power a Teradeck bolt, DJI follow focus and a Small HD 702? Is there a cable that I can use to control start/stop and other functions as well using the c300 lanc or remote port? Thanks - sorry for the noob questions.
