Best third-party batteries for Canon RF mount mirrorless cameras?

Question

Ugh I am so annoyed right now because I just dropped way too much money on an R6 Mark II and now I realize I only have one battery and the official Canon ones are like eighty bucks a pop which is just highway robbery if you ask me. I have a big wedding shoot coming up this Saturday in downtown Chicago and I definitely need at least three more spares but I'm totally tapped out on my gear budget for the month after buying that 24-70 lens.

Ive been looking at the Neewer ones that have the built-in USB-C port on the side of the battery itself which seems super handy for charging in my car between locations but then I saw the Wasabi Power dual packs are way cheaper and they usually have a decent reputation with my older DSLRs. My main worry is that stupid performance hit where the camera wont do the full frames per second or the shutter icon turns white because it doesnt detect a genuine chip.

I'm really torn between those Neewer USB-C ones and the standard Wasabi Power set because I dont want to buy junk that triggers a compatibility error message every time I turn the camera on but I also cant afford $240 for three Canon batteries right now. Which one actually keeps the high-speed burst mode active?

Honestly, I totally get the frustration with Canon prices, but unfortunately, the third-party market is a bit of a mess for the R6II right now. Ive had issues with the camera refusing to hit that top burst speed because the chip just isnt recognized correctly. It's really not as good as expected when youre shooting professional work.

The Wasabi Power LP-E6NH 2250mAh 2-Pack is okay for backups, but the voltage stability just isnt there for the 12fps mechanical shutter.

I had high hopes for the Neewer LP-E6NH USB-C Rechargeable Battery 2400mAh but they honestly ran way too hot during long bursts... kinda scary tbh. Safety is a huge deal for me, and Ive seen too many cheap cells swell up in the tray. If you can, just grab one real Canon LP-E6NH Lithium-Ion Battery for the ceremony and use the others for light stuff. Let me know if you have more questions about chargers or anything!

> Which one actually keeps the high-speed burst mode active? Saw your post earlier and wanted to chime in. Over the years I've tested dozens of these, and the SmallRig LP-E6NH USB-C 2400mAh is the standout imo. It hits the full 2400mAh capacity and actually maintains that green H+ burst icon on my R6II. Most cheap clones dont hold the voltage high enough, but these are legit tho. Definitely worth the $40 for your shoot.

Tbh I totally feel the pain of gear burnout after a big purchase like an R6II. The worry about high-speed burst issues was real for me when I started shooting sports because if you lose that green H+ icon it basically ruins the whole point of a fast mirrorless body. After spending way too much time researching this, I eventually landed on the SmallRig LP-E6NH USB-C Rechargeable Camera Battery 2400mAh and honestly I couldnt be happier. Ngl, the built-in USB-C port is a game changer. Usually I just plug them into my phone charger in the car and theyre ready to go. They show up perfectly in the camera menu with the full three bars for battery health too. Another one Ive had good luck with is the K&F Concept LP-E6NH Battery Replacement with USB-C Charging Port 2250mAh. They both seem to handle the power draw requirements for the R6 Mark II without triggering that compatibility warning or slowing down the frame rate. These have been in my bag for a few months now and they havent swelled or lost capacity yet which is always my fear with the cheaper knockoffs. If youre really tight on cash, the BM Premium LP-E6NH 2-Pack and Dual Charger is usually the cheapest way to get the high capacity cells without the USB-C bells and whistles, even tho the SmallRig ones are my preferred choice for the convenience. Good luck with the wedding! Downtown Chicago is gonna be gorgeous for photos.
