Oh man, I feel u. When I first jumped to the R6 from my old 5D, I was honestly shocked at how fast it chewed through power. I went through a whole phase of trial and error with cheap batteries cuz I realy didn't wanna drop $80 each either... it's just too much for a piece of plastic and some cells. I tried a few super cheap ones from eBay that were basically paperweights, but I've found some solid gems since then. For your situation, I would suggest going with the SmallRig LP-E6NH USB-C Rechargeable Camera Battery 2400mAh. These are a game changer because they have a USB-C port right on the battery itself, so you can charge them with a power bank in your bag. Plus, they usually trigger the green H+ mode on my R6 without any of those annoying 'non-genuine' popups that drive me crazy. Here's what I recommend based on my kit: * SmallRig LP-E6NH USB-C Rechargeable Camera Battery 2400mAh: Best for travel since you skip the wall charger.
* BM Premium LP-E6NH High Capacity Battery: Super budget-friendly and they've been reliable for long shoots.
* Wasabi Power LP-E6NH Battery (2250mAh): A classic choice, though I've noticed they lose the high-speed burst capability a bit sooner than the others. Basically, the secret is making sure they're specifically rated as NH. If you get the older 'N' versions, you'll definitely lose that fast mechanical shutter speed. The R6 is kinda picky about voltage to maintain that H+ icon, so cheaping out too much can bite you. But yeah, the SmallRig ones are the way to go imo. Good luck!

So, jumping in here! Honestly, I totally get the frustration with the official Canon prices... it is literally daylight robbery. As someone who geeks out on voltage specs and internal resistance, the main issue with the EOS R6 is that it's super picky about the "High-Speed Display" and H+ burst mode. To get that green H+ icon, the camera's firmware needs to communicate with the battery's chip to verify it can handle the specific current draw required for 12fps mechanical. I have spent way too much time testing clones cuz I refused to pay the Canon tax too. Here's what I recommend for a mirrorless setup: 1. SmallRig LP-E6NH USB-C Rechargeable Camera Battery 2400mAh
- **Pros:** This is lowkey a game changer because of the built-in USB-C port on the battery itself. You can charge it literally anywhere without a bulky cradle. In my testing, it actually triggers the H+ mode on the R6 perfectly when it's above about 60-70% charge.
- **Cons:** It is a bit pricier than the bottom-tier clones, but still half the price of OEM. Also, the voltage curve drops off a bit faster than the original. 2. BM Premium LP-E6NH High Capacity 2250mAh Li-ion Battery
- **Pros:** These are basically the budget kings. I've got a couple and they consistently show up as "LP-E6NH" in the battery info menu, which is huge for tracking your shutter count and health. They're super reliable for the price point.
- **Cons:** They tend to lose their max capacity a bit faster over many recharge cycles compared to the Canon ones. (At least thats what happened with mine after a year of heavy use). Tbh, if you want that H+ burst consistently, you just gotta keep them topped off. But yeah, these two are way better than the super cheap generic stuff. gl! 👍

Saved for later, ty!

@Reply #6 - good point! Honestly ive been using a couple of different third-party sets for over a year now and im really satisfied with how theyve held up, basically no complaints on my end. Just wanted to clarify a few things before i suggest anything... what kind of shooting do you mostly do? Are you doing long video sets or mostly fast-action stuff where you absolutely need that green H+ icon to stay active? Knowing if you plan to charge them inside the camera via USB-C or if you prefer an external charger would be super helpful too. Just want to make sure i suggest something that actually fits your workflow.

I saw this earlier and I realy agree with what was said about the handshake and voltage stuff... it sounds like a total headache. Tbh I'm still pretty new to the R6 and I'm honestly terrified of putting a cheap battery in and having it leak or fry the internals. I’ve been looking into more of a DIY self-service approach for power instead of just buying more internal packs. * Just get a power bank from a brand like Anker, you can't go wrong with their quality.
* Maybe try a dummy battery setup if you are doing long shoots in one place?
* Use a PD-rated external source from any big name electronics brand. I mean, is it actually safe to run the camera off a big external battery for a long time? I’m realy worried about the heat or if it might hurt the sensor... basically just want to be safe but save some money.

Just caught up with this thread and I really agree with what EmeraldEcho mentioned about the discharge curves. I've been quite satisfied with how some third-party chips have evolved lately, but I've gotta add a word of caution regarding firmware updates. Its super common for a camera update to suddenly break the battery's ability to communicate its health status. I've seen units that worked perfectly one day and then stopped showing the remaining percentage the next. Its basically like flying blind without a fuel gauge. Also, definitely watch out for the USB-C in-camera charging compatibility. Many budget batteries dont actually support the specific Power Delivery requirements of the R6. If the handshake isn't perfect, you might find the camera refusing to charge at all, or worse, it could potentially overheat the internal circuitry. Im happy with my current spares, but I'm always meticulous about checking if the chips are listed as fully decoded for the latest firmware versions before I commit to a purchase. It really saves a lot of frustration during long shoot days when you need that data to be accurate.

In my experience, I tried some cheapies and was sooo disappointed... they never hit H+ speeds cuz the voltage drops. Honestly, budget brands are realy a gamble for fast bursts, idk.

Totally agree about the handshake protocol—that’s the real bottleneck. It’s basically a cat-and-mouse game between Canon’s proprietary firmware and the reverse-engineered chips in these third-party units. From a market analysis perspective, here are a few things to consider: * Not 100% sure, but I think the discrepancy in H+ performance usually comes down to the discharge curve. While OEM uses top-tier cells, many budget brands source from secondary manufacturers where the voltage drops off way too sharply under a heavy load.
* IIRC, there was some talk on a developer forum about how the R6 monitors internal resistance in real-time. If the battery can't maintain a specific threshold during a burst, the camera just throttles the drive speed to protect the electronics.
* I’ve heard rumors that some newer batches of generics are finally getting the PD (Power Delivery) handshake right for in-camera charging, but it’s still a bit hit or miss depending on which firmware version you’re running. It’s a gamble tbh. You're basically trading long-term reliability for that lower entry price. Sometimes that "Canon tax" is just the cost of consistent QC and tighter tolerances.
