The Dual TB50 Battery Mount offers a battery hot-swapping feature when mounted with two TB50 Intelligent Batteries. The two P-Tap ports at the back of the mount provide 14.4V power even when the mount is used as a standalone power source for other equipment such as camera, wireless video transmitter, or field monitors.When you need to install the mount remotely to power the Ronin 2, simply route the power through the POWER OUT port.
