The Core SWX V-Mount JetPack for Epic and Scarlet is a battery and power output adapter, featuring a V- for a battery and six outputs for powering various accessories. Specifically, the outputs include two D-taps, one 5V Lemo, two 12V Lemos, and one USB output. You can use the D-taps, for example, to power compatible monitors and lights and the USB out to power Redmote. Please note: JetPack passes battery data to the Epic/Scarlet if you're using batteries with communication protocol.
Three 1/4" threads are available for mounting. You would need to use a plate that configures well with your rig. An M3 screw pattern is also available for attaching a Wooden Camera Quick Back plate, which allows mounting directly to the camera. An optional JetPack cheese plate can be attached to additionally provide thirteen 1/4" and ten 3/8" threads.
