I use this battery belt to keep my setup as light as possible when using the Ronin Original, since it's not an incredibly strong gimbal. If you're renting the Ronin Original (https://www.sharegrid.com/losangeles/l/85555?type=rent), you get $10 off this belt.
All my other gimbals, you don't need this battery belt, only the ronin 1. I suppose the Movi Pro if you wanted, however, I never found it necessary to use this on a Movi Pro because that gimbal is strong enough to handle it.
