R5c usb-c dummy battery issue

Trottsky — Mon, 23 Jan 2023 20:49:41 GMT

After switching out of video mode, camera becomes unable to power on. Power must be removed and re-established to use camera again. I have tried two different usb-c dummy batteries, both brand new. Both supply the camera with the specified voltage and amps.

Equipment:
R5c
Dummy battery
PD USB-C power bank 100w

Steps to reproduce:
1. Connect camera, dummy battery and power bank
2. Switch camera into Video mode
3. Switch camera to Photo mode

I have tried turning off sensor cleaning at shutdown, it has no effect

Greetings,

Please confirm FW version?

What dummy batteries are you using? (brand / model) etc.

How are you connecting power to them? (Please be specific)

What is the brand and model of your PD? (100w) great, what is it.

Lens - What brand and model, are you using an adapter (brand?) Does this happen with all lenses, just one, etc.

And last, what happens if you connect the PD directly to the camera's USB-C connector? (Advise you use your cord caddy protector)

Hi Rick, thanks for taking a look at this.

The camera is running firmware 1.0.2.1

Dummy batteries are:

Connection is simple, dummy battery in camera, USB-C connected to USB-C port on power bank

PD is Baseus Blade

Lenses don't seem to make a difference, I have tested RF70-200 f4, Sigma Art & Canon EF lenses via adapter.

Directly connecting the PD with the camera's USB-C port works fine, provided a LP-E6NH is inserted. Without the battery inserted the camera doesn't power on at all. Is this normal behaviour?

I am using the supplied Canon caddy protector.

On paper, your PD appears to support any power requirements of the camera.

9v, 3A = 27w (30w)

8.4v, 3.7 A = 31w

I'll test my PD today and see if it allows a battery swap. I don't have any dummy batteries. I just connect directly which you said works.

Yes for normal video work I have been using the PD connected directly to the camera's USB-C port for many months now, no issues there. I get about 3 hours of runtime for R5c + monitor + accessories, with a recharge time of only 1 hour.

The dummy battery setup is for e-com fashion shoots in the studio, in this situation the camera is tethered to the computer via USB-C so my client can review the images. In these shoots my clients now want video shot simultaneously so I am switching back and forth between video and photo modes throughout the day. Until now I have been doing this with the LP-E6NH battery packs, but I am chewing through those faster than I can recharge them.

Greetings,

Sorry for my late reply. I don't have a dummy battery to test with I'm afraid.

In active photo mode with USB-PD connected to USB terminal and battery inserted, the camera shuts off when the battery door is opened.

In active video mode with USB-PD connected to USB terminal and battery inserted, the camera remains *on* when the battery door is opened. If you are recording, this also continues. The camera also continues to run if the battery is removed... So hot swap is possible in video mode.

Hi Rick,

I have just tested this:

In active video mode with USB-PD connected to USB terminal and battery inserted, the camera remains *on* when the battery door is opened. If you are recording, this also continues. The camera also continues to run if the battery is removed... So hot swap is possible in video mode.

Can confirm it is working correctly, I must have been in Photo mode when I checked earlier.

Is there somewhere I can raise the original dummy battery issue with canon directly?

Hi Trottsky,

I'm glad to see the USB-C power suggestion shadowsports made is working for you. In regards to the dummy battery issue we would recommend loading a Canon battery in the camera and check to see if the same thing happens. When you check this done have any other power sources connected. If this same thing happens with a battery loaded by itself that indicates there is an issue with the camera. If it is only happening when you have the dummy battery loaded that indicates there is an issue with the dummy battery.

If the issue is with the dummy battery we would recommend contacting the maker of the dummy battery. Through Canon support we only have information on products made by Canon itself. If you want to try the Canon dummy battery power adapter there are two pieces to it and you would need both. The DC Coupler DR-E6C is the part that plugs into the battery compartment and the AC Adapter CA-946 is the part that plugs into your power supply.

If the issue is happening with a Canon battery loaded in the camera we would recommend sending the camera in for repair.

The Canon U.S.A., Inc. online repair portal allows you to set up service in a few simple steps. The repair portal gives you the ability to set up service for multiple pieces of equipment at once, and to receive a repair estimate in the majority of cases, depending on your model and issue.

Hi Hazel, thanks for helping out.

Yes camera operation is normal when using battery only.

I had a feeling you would say the dummy batteries are at fault, but what are the chances that two brand new dummy batteries from different manufacturers exhibit the exact same behaviour?

Appreciate your suggestion regarding the canon power supply, but my rig draws power from a PD power bank and the solution must use USB-C. Is Canon likely to produce a USB-C dummy battery? I would buy it 🙂

Hi Trottsky,

I just realized something. The R5 C requires 3.0Amps. The Canon DR-E6 is 2.0A. The DR-E6C (R5 C) specific is 3.0A.

I noted that one of your dummy batts is 2.0A. Is the other 2.0 as well? I suspect this is the issue. Guessing.

Hi Rick,

Apologies for the late reply, we've been dealing with some serious flooding over here in Auckland NZ.

I think you're right, the amps is likely very relevant to this situation. The second dummy battery has an output of "2~3A". I have done some testing with the LP-E6N and LP-E6NH batteries, and found some surprising results.

Firstly, some output calculations from these batteries (please correct me if I am wrong, I'm no electronics expert) - Both Canon branded batteries.

LP-E6N: 7.2V, 14Wh = 2.0A

LP-E6NH: 7.2V, 16Wh = 2.2A

So the LP-E6NH doesn't even reach 3.0A, and works perfectly fine.

And whats really interesting is the LP-E6N causes the exact some issue (camera locks up when turned off from Video mode).

So if you have an LP-E6N lying around Rick, I would be very interested to see if your R5c exhibits the same behaviour.

Greetings,

LP-E6N... I do. Have at least 3 for my 6D2. I know they work in the R5. I thought they "could" work in the R5 C as well. I don't remember for sure, and have never tried. I think there is a charging limitation - cannot be charged (in the camera or grip?). I just don't remember which. At work, will try this evening.

Hi Rick, any updates on the test?
