The Anton Bauer 8075-0267 Gold Mount battery plate with C-Series DC connector. Works with Canon C100, C300, and C500. Voltage regulator integrated in the plate provides constant 9V to camera. Two P-Taps on plate provide 12-16V depending on battery connected.
Cable exits the right side of the plate allowing neat looping and insertion into the camera. The 16" cable minimizes cable excess while still being able to reach positions further away from the camera as necessary.
