Recently I have been stumped with an issue I hope you can help me solve. I have a rig with the R5C and the RF 24-105 mm z lens. I'm looking to record in RAW 8k LT 60 FPS. I have an external battery power supply that requires a DTap to Dummy Battery connection to power the camera and a USBC PD from the camera to the Battery to power the lens (otherwise it states there is not enough power being delivered for the lens). Is there a way to power both the lens and the camera through a dummy battery or other means. The reason I ask is because I need to USBC port on the camera to be free to plug in a different device that needs it. Maybe using a dummy batter to USBC to the battery will fix it? I'm not really sure. Hope you know more than I do and can help me, much appreciated!!

Greetings,
Can you provide more information about the gear / equipment? You can power the camera with a Dtap to dummy battery. I believe KondorBlue is one of the few that supports 8k/60. The others only support 30
I've also seen this done with a compatible "Y" cable for the USB-C port. This way you can power the camera & lens, and have a connection for the "other device" Care to tell us what that device is?
The camera needs at minimum 45w 9v and 3 amps for PD.

Hi! Currently using the Dtap Dummy battery provide by Smallrig: https://a.co/d/9NY0rnq seems to work fine. Then I have a 240w compatible usbc to usbc also going into external power supply for camera lens. The external power supply is the Smallrig VB212 battery: https://a.co/d/7DQUx9D the other device I want to be plugged in that requires a usbc connection is Smallrig’s new Rotating Side Handle with Trigger REC for Select Canon & BMD Cameras: B&H#SM5235
If you know of a compatible Y cable for the canon r5c usbc port that should probably solve my issue, but I couldn’t find one myself for sure.
