The DJI Ronin 2 Dual TB50 Battery Mount is a replacement for the dual mount that comes included with the gimbal. It attaches to the Ronin 2 and plugs into dedicated contacts to support up to two TB50 batteries with hot-swapping. It can also be connected from a distance using optional long DC power cables from DJI (part #s CP.ZM.00000085.01 and CP.ZM.00000052.01).
The battery mount also offers two 14.4V D-Tap ports. When the battery mount isn't being used to power the gimbal, the D-Tap ports can be used to power accessories.
