This Quick Release Plate from Hawk-Woods is designed for the ST-38 or ST-75 Sticky Battery for quickly mounting and unmounting the battery. It is designed to mount on drones or rigs in a proper balancing position so you can change out the battery without the need to rebalance your rig. The battery snaps right into the plate and has four mounting holes for screws. The plate does not block any of the D-Tap ports on the battery.
