I totally get the frustration with the prices, honestly it’s getting out of hand lately. But for the R5 Mark II, I've been really satisfied with the standard Canon BG-R20 Battery Grip so far. I checked out some early third-party options but with a wedding in three weeks, you really don't want to risk the camera throttling your speeds or acting buggy mid-event. The thing is, the R5 II is insanely picky about power draw. To hit 30fps and use the new AF tech, it needs the high-output Canon LP-E6P Lithium-Ion Battery. Third-party grips often have mediocre voltage communication, which can basically trick the camera into thinking it doesn't have enough juice for the high-performance modes. You might find it works for single shots but then fails when you try a high-speed burst. Here is why I am sticking with the official one for now:

• Performance: It handles the high-speed bursts perfectly without any lag or communication errors.
• Build: The weather sealing matches the body, which is a lifesaver if it rains during an outdoor ceremony.
• Airflow: It is designed specifically to not block the bottom vents so the passive cooling still works fine. You definitely don't need the version with the fan for wedding work. Just get the base Canon BG-R20 Battery Grip and skip the extra cost. It balances the camera way better when you're shooting with a heavy lens like the Canon RF 70-200mm f/2.8L IS USM all day. Paying the canon tax sucks, but having a camera glitch out in front of a bride is way worse.

> I heard the R5 II has some weird power requirements for the new features so I'm worried a cheap knockoff might mess with the performance I was in the exact same spot about a month ago, totally frustrated by that five hundred dollar price tag. Since I do a lot of fast-paced event work, I really needed the vertical stability but couldn't stomach the Canon tax. I actually tried slapping on my old Neewer BG-R10 Vertical Battery Grip just to see if it would work. It fits perfectly fine on the mount, but the software is pretty smart. It basically treats the camera like it has a low-power source, so you lose out on the top-tier 30fps burst and some of the AI autofocus features. It’s definitely not worth it for a wedding if you need that speed... kind of a letdown tbh. I ended up going a different route and I’m super satisfied with it. I grabbed the SmallRig L-Shape Mount Plate for Canon EOS R5 Mark II 4751 to help with the hand cramping. It's basically a beefy metal extension that makes the camera much taller. No extra buttons, but honestly? It feels more solid than the plastic grips anyway and gives your pinky a solid place to rest. Then I paired that with a few SmallRig LP-E6P Rechargeable Camera Battery units. These are way more affordable and they actually talk to the R5 II properly so you get the full performance modes. I shot a whole weekend with that setup and had zero issues. Unless you are shooting heavy 8K raw video, you probably don't even need that fan version anyway.

Quick reply while I have a sec because that 30fps burst is amazing! You absolutely need that LP-E6P circuitry to maintain high performance without hitting power throttles. To save some serious cash, check these out:

• Watson LP-E6P 2130mAh Lithium-Ion Battery is a fantastic, high-capacity alternative to the pricey Canon ones.
• Vello BG-C20 Battery Grip for Canon R5 II is the main third-party option to track.
• Neewer BG-R20 Replacement Grip should be dropping soon!
