Does anyone have a solid recommendation for a battery grip or a cage setup for the Canon R7 specifically for long video shoots? I've been doing a ton of digging and I'm honestly torn between just getting a cage or trying one of those third-party battery grips since Canon decided not to make an official one for this body for some reason.
I saw the SmallRig Black Mamba cage is popular but I'm worried it wont actually help with the battery life issues I'm having. I'm shooting a wedding in Chicago next month and I'm really nervous about the R7's battery life when shooting 4K 60fps all day. I read that some people use the Neewer or BG-R10 clones but then I see other reviews saying the communication with the camera is buggy and it shows non-genuine battery errors which would be a nightmare mid-ceremony. My hands are also kinda big so the R7 feels a bit tiny when I have a heavy lens on it.
- need more grip area for my hands
- must last at least 3-4 hours of intermittent shooting
- budget is around $200 max for the rig
- needs to not block the flip out screen
Is it better to just get a cage and mount a power bank or a small v-mount to the back or is there a grip that actually works well? I'm just trying to avoid a messy setup with cables everywhere if I can help it...

I honestly wasted money on the Neewer BG-R10 Replacement Battery Grip and it was a total letdown... kept losing connection mid-shoot. Unfortunately, those third-party grips just arent reliable for weddings. The SmallRig Black Mamba Cage for Canon EOS R7 is better for handling big lenses and doesnt block the screen, but it doesnt solve power. I eventually just rigged a power bank to the cage because those grips are just too buggy.

Like someone mentioned, grips arent reliable. The cage adds the bulk you need. Try this:
- SmallRig 4003 Cage for Canon EOS R7
- SmallRig 2915 Power Bank Adapter Mount This handles 9V PD requirements reliably.

Are you shooting 10-bit? Fried a port using cheap cables once, so be careful.
- Nitze Canon R7 Full Cage TP-R7
- SmallRig LP-E6NH USB-C Rechargeable Battery 2400mAh Dont trust grips tho.

Been dealing with the exact same frustration lately. Its honestly such a letdown that Canon ignored the pro-sumer segment by skipping a first-party grip for the R7. I tried a few knockoffs and they were junk... connection drops are just not worth the risk during a ceremony. Since you need that extra height for your hands and reliable power, I finally settled on a rig that doesnt feel like a science project.
- 8Sinn Cage for Canon EOS R7 provides a much better mounting surface than the thinner cages.
- SmallRig NP-F Battery Adapter Plate Lite 3018 mounted to the side or top.
- SmallRig LP-E6NH Dummy Battery 4330 to connect the plate to the camera.
- SmallRig Top Handle with Cold Shoe 1638 to give you something solid to grab. Using an NP-F970 battery on that plate will last you almost the whole wedding day. Its a bit heavier but way more professional than hanging a power bank off the side. Just make sure your cables are secured so they dont wiggle the port.
