The Ronin-S allowed us to power external devices like our cameras from the Ronin-S handgrip battery power. Apparently the RS2 now requires a special handshake with the device and only outputs 8V. Paul Pan mentioned that he discovered the internal wiring can support this. Does this mean that a possible future firmware update could allow for 12V output to power our cameras like we currently do with the Ronin-S? This is a huge deal for people using cameras like the BMPCC 4K that have very poor battery life.

I had messaged DJI and about the same thing they said they do not anticipate having external dummy batteries for RS2.  It sucks because thats a feature I always use for my ronin s

Sorry to tell that BMPCC 4K is not able to be charged by the DJI RS 2. Your feedback will be noted down and forward to the engineers to notice. 323.png

Hi, may I know the specific camera do you use? The DJI RS 2 supports using a multi-camera control cable to power some cameras. For more details, please refer to the camera compatibility list on DJI's official website: https://www.dji.com/uk/support/compatibility?product=rs-2.

Oh....thats....awful! And here I am sitting in front of this new RS2 that I'm now going to have to pack back up and ship to returns.  Sad.  If this is a firmware thing and it's on priority list of things to do, might be able to wait, but if I don't see something encouraging about this (or a way to get power to this camera that doesn't involve creating unbalancing issues), it just has to go back.   Crane 3S was what I was going to buy before the release of RS2.  Hope I didn't make a big mistake.

I use the bmpcc 6k.

Hello, according to the camera protocol from the BMPCC 4K/6K, it can be charged from the external power source when it is power off. So we cannot shoot video and charge the camera by the gimbal power at the same time.

Hope this helps.

Interesting...will test, though it's sort of important that it can be charged while on.  Trying to think of a way to power the camera on this rig without doing something crazy like mounting a vmount battery directly to the camera. Even if I put a rig around the gimbal and mounted a vmount battery to that...still have a cable hanging out there and preventing range of motion and creating balance issues.

Oh wow, what a terrible disappointment.  No support for power, ISO, aperture, shutter... ANYthing on the Sony A7S3 either!???  
Is this a Sony limitation, or a DJI limitation?

I'm confused by your statement. It sounds like you're saying that you cannot charge the camera from the gimbal while the camera is on due to BMPCC 4K protocol... but the original Ronin-S provides power to the BMPCC 4K since it has the capability of outputting 12V. You may want to speak to Paul Pan on this as he mentioned in a Facebook group that the internal wiring of the RS2 does support this, so it appears that maybe a firmware update could enable this capability?

The table above says RS2 can control the BMPCC4k's iso and aperture.

Hi there, it's true that the BMPCC4K/6K can not be powered through the camera's USB-C input, and that power-wise, the camera's USB-C input can only charge an internal camera battery if the camera is turned off.

I think what the original poster and I are actually interested in is how the RS2 can power the BMPCC4K/6K using the camera's separate 12v input (see the attached image). On the older Ronin S, I powered the BMPCC4K via its 12v 2-pin input using the Ronin-S's 12v accessory output (see image of the cable I made).







This is CRUCIAL for all BMPCC4K/6K / Ronin users because the camera has very poor battery life and needs to be powered externally. I was really disappointed to learn that the RS2 wouldn't have the 12v accessory outlets that the original Ronin-S  has.

Please, PLEASE wonderful DJI engineers! If at all possible - allow 12v through the RS2 usb-c accessory ports. USB-C to 2-pin cables already exist on Aliexpress (see my third image). I believe the camera draws 22w while recording, with an external SSD connected, screen brightness at full and an active lens attached.

100% agree, the inability to power the BMPCC 4K/6K from the RS2 is a deal-breaker for me. There are a lot of great new features but I would defiantly not upgrade without a way to power my camera.

Agreed. Even having the possibility of a dummy battery being supplied by one of the 3 usb-c ports would be amazing, if the 12v isn’t feasible. Just SOME way of powering the camera off of the gimbal’s battery. Tilta’s dual handle / v-mount battery plate accessory is less than ideal, defeats the weight reduction benefit of the RS2 and the battery plate is off to one side, making the handling of the weight awkward for one arm.

I'm having the same issue with my Sony A6500. The battery cant go longer than 30 minutes without dying so I used a dummy battery powered by the Ronin-S. Is there a way to power my Sony like the Ronin-S did?

We have the same concerns. We're attempting to run a BMPCC4K with our RS2, but the inability to power the camera through the gimbal is a MAJOR problem.

We are also having trouble with getting our Nucleus-Nano motor to operate properly when plugged into the RS2's accessory ports. We would have purchased a follow focus handwheel from DJI, but they don't have one that's compatible with their motor, so we were forced to buy the Tilta solution.

On the surface it seemed like the RS2 was a really awesome product, but the reality is that it has MAJOR deficiencies. Hopefully DJI is able to fix these problems in firmware or we're going to have to sell this thing.

I am more than a little disappointed that the Ronin-RS2 doesn’t offer a way to power my BMPCC6K. The Ronin-S had no problems powering the BMPCC6K along with a 3rd-Party focus motor. I hope DJI will address this shortcoming in what looked on paper to be the “killer” gimbal for cameras in this range/size.
