Canon R5C drains LPE6NH battery even with USB-C port connection with NP-F960 battery

[YULI]

I have a inquiry regarding the Canon R5C camera: currently working with: 

- NP-F SmallRig board with new USB-C output.

- Kastar For Son NP-F960/970 lithium battery 7.4V 8700mAh, 64.5Wh new

- Brand new original Canon USB-C to USB-C cable that comes with the camera

- Brand new Canon R5C camera that has been working with for 3 months now

- Brand new, original Canon LPE6NH battery

- Camera firmware 1.0.7.1

- Ronin RS3 PRO stabilizer

 SCENARIO #1: Canon LPE6NH battery runs out of power.  Why?

 1. The battery is placed in the camera, fully charged to 100%.

2.  Connect the camera to one end of the USB-C cable and the SmallRig board to the other end of the USB-C cable. Place the Kastar For Son NP-F960/970 lithium battery 7.4V 8700mAh, 64.5Wh with a 100% charge on the SmallRig board.

 3. The camera is turned on in Video Mode and after a while of work, it is noticed that the Canon LPE6NH battery has no charge; it is as if the camera is not taking the power supply from the USB-C port. However, the camera can continue to work in Video Mode. This was not the case 2 months ago when the camera was purchased.

 SCENARIO #2: Camera shuts down when removing the Canon LPE6NH batter. Is it normal?

 1. The camera is still connected to the Kastar NP-F960/970 battery through its USB-C port, I decide to remove the Canon LPE6NH battery to replace it with a 100% charged one, but when I do this, the camera turns off. Is this normal? Shouldn't the camera still be on and taking the power coming from its USB-C port?

 SCENARIO #3: Connection with Ronin RS3 PRO stabilizer

1. The stabilized Ronin RS3 PRO does not activate recording by USB-C connection to the camera.

 ----------------------------------------------------------------------------------------------------

TEST #1: Charging the Canon LPE6NH battery

 1. The Canon LPE6NH battery is placed inside the camera, either slightly discharged or fully charged.

 2. To one end of the USB-C cable is connected the camera and to the other end of the USB-C cable, the SmallRig board, on the latter, is placed the Kastar For Son NP-F960/970 lithium battery 7.4V 8700mAh, 64.5Wh with a 100% charge.

 3. The camera is turned off/OFF and the Canon LPE6NH battery is charged correctly; while charging, the lower bulb on the right side lights green and the upper LCD display shows a flash icon inside a battery icon, when the battery charges to 100%, FULL is displayed.

 TEST #2: Turning the camera on in Video Mode

 1. Place a slightly discharged or fully charged Canon LPE6NH battery inside the camera.

 2. Connect the camera to one end of the USB-C cable and the SmallRig board to the other end of the USB-C cable. Place the Kastar For Son NP-F960/970 lithium battery 7.4V 8700mAh, 64.5Wh with a 100% charge on the SmallRig board.

 3. Turn on the camera in Video Mode and the green light bulb, located on the upper left side, lights up.

 TEST #3: Charging a MacBook Pro

 1. To one end of the original Canon USB-C cable, a MacBook 2019 16" laptop computer is connected, and to the other end of the USB-C cable, the SmallRig board, on the latter, the Kastar For Son NP-F960/970 lithium 7.4V 8700mAh, 64.5Wh battery is placed with a 100% charge.

 2. The computer receives charge from the SmallRig board correctly, until it reaches 100%.

 TEST #4: Using the MacBook Pro Charger

 1. To the camera is connected, the original MacBook Pro 2019 16" MacBook Pro laptop computer charger and USB-C cable. This charger is USB-PD 20.5V 4.7A or 15.0V 3.0A or 9.0V A 3.0A or 5.2V A 3.0, which does receive the charge from this charger, via USB-C port.

 2. The camera is off/OFF and the Canon LPE6NH battery is receiving charge correctly; while charging, the bottom bulb on the right side lights green and the top LCD display shows a flash icon inside a battery icon, when the battery charges to 100%, it shows FULL.

I hope you can help me to know if this is normal with the R5C model or should I do some update, firmware reversal

Hello
Do you have any news?

Greetings,

AtticusLake performed the test and his battery remained full.  (see his reply on page 1)

I'm testing now.  Keep in mind both of us are using USB-C PD's with our cameras.

Hi Yuli,

I'm sorry I didn't post sooner. I only recorded for 37 minutes. 4K 24p. 

Battery with 100% charge.  Connect USB-C PD.  Turn on camera.  Start recording. 🕣⏳🕒 Stop recording.  Power off camera.  Disconnect PD.  Turn on camera.  Battery still full.

Hi Yuli,

It looks like you need the "Advanced" battery plate model for the R5 C.  The specs also say it supports connection to a "dummy battery"

1. Compatible with NP-F type batteries, paired with DC to LP-E6NH dummy battery power cable, providing external power supply for Canon EOS R5 / R5C, BMPCC 4K / 6K and various mirrorless cameras

The older NP-F model does not appear to support this body.  Neither may be compatible with USB-C PD (May require dummy battery)

Hi shadowsports

🙂

Thank you. I will try a dummy battery and V-Mount.
