Great battery, I used it for an R6 camera and its durability was superior to the original. What I liked most was the way it charges. You connect a USB C cable directly to the battery and you don't have to take up space with an extra charger. An excellent battery.

These are a direct fit/replacement and confirmed operational for my cameras, Canon 5D M2 and 7D. These batteries came with a close to full charge. I put one in an original Canon charger, and the other battery I plugged into a USB charger, with the included USB-C cable that directly connects to a USB-C port on the back of the battery itself. This is such a cool feature to be able to charge these batteries with just a cable; very convenient!
So far so good, these seem to operate well and hold a charge comparable to Canon OEM batteries. The thing that I have experienced with other imitation brand batteries, is that their longevity isn’t there. So, I’ll have to give it a year or two and revisit the status of these batteries in comparison to the OEM batteries I have. At the price these sell for, and the option to charge them directly with a USB-C cable makes these batteries a definitive choice; highly recommended!

K&F Concept has the right idea with these batteries. Everything is moving to USB-C now. Everywhere you look, you will find lithium-ion and USB-C. This is a wonderful thing. No special charger. No special cable. You can charge these pretty much anywhere. If you can charge your phone - even iPhones will have USB-C going forward - you can charge these batteries. And as K&F Concept has shown, the addition of a USB-C connector need not add to the cost.

Speaking of cost, if you've purchased LP-E6 batteries for a Canon "pro" DSLR, you know how painful it is to shop OEM. At the current time, these batteries cost roughly one-third the cost and don't require a special charger. This should be a no-brainer.

My Canon 6D does not display any warnings about the battery when identifying it and had no issues with registering it for tracking its state of health.

I love the cleverness and convenience of a built-in USB-C port, and it never hurts to have more batteries on hand. What remains to be seen is how well these batteries will hold up over time. If cell and circuit quality is there, these should serve me well for years to come.

As expected, these batteries are not as good as my OEM Canon batteries. They don't last as long taking video nor take as many pictures. Still, these are pretty good. I don't know if this feature is a good idea, but the USB-C charging port built into the battery is a good idea if it works without problems. I haven't tried it out yet because I have my regular charger and the charger that came with these batteries. The USB-C can not only charge these batteries but it can charge other devices such as a cell phone. It seems like a good idea to include that in all medium and high capacity batteries if it doesn't add too much to the cost or hurt reliability. You never know when it might come in handy.

Got these as backup batteries for my work Canon R5. So far they work great, the hardest part was fiinding a USB-C charger to charge them up. Comes with the cable but not the wall charger. These batteries also charged up on my third-party LP-E6NH duplex wall charger, so very convenient. It is also reccognized by my third-party battery grip, and read out levels correctly. This is a great battery for keeping in my pocket of my work vest for emergencies. It can also be charge from the USB cable on my car charger, another benefit. I also like the fact that it is a different color, very easy to tell at a glance which are Canon OEM and which are the K&F. When charging these, there is a little LCD at the top that turns from red (while charging) to green (cwhen completed). All in all, I glad I ordered these and hope to wear them out in my R5 system in the next few years!

When you purchase a Canon EOS R5, R6, R7 (etc), it comes with a Canon LP-E6NH battery. The LP-E6NH looks identical to the older LP-E6 battery and these R series cameras can use them both, according to Canon.

But there is a practical difference (aside from the higher battery capacity of the newer battery): These Canon mirrorless cameras are capable of in-camera battery charging via the camera's USB-C port - but only if the battery is LP-E6NH. (This feature is convenient when traveling, for example. No worries even if you forget to bring a battery charger. You can charge a genuine Canon LP-E6NH inside the camera by connecting to a USB-C charger capable of PD (Power Delivery) rapid charging.)

Now, in the past I purchased a few generic "LP-E6NH" batteries from Amazon. But my EOS R7 would recognized them as "LP-E6" batteries. (So no in-camera charging option with them.)

To my pleasant surprise, with these K&F batteries, my EOS R7 camera recognizes them as "LP-E6NH". (See photo.) I also confirmed that the EOS R7 camera charged this K&F battery in-camera, via the camera's USB-C port, as expected. (Unlike the case with LP-E6 batteries from other sellers.)

These K&F batteries are equipped with a USB-C port on the battery itself. So you have two options for charging these: 1) Charging them inside the camera, or 2) outside, in both cases using a commonly available USB-C charger. (No need for a battery charger specific to LP-E6/E6NH.)

As far as the battery capacity/longevity, in my past experience non-OEM batteries never last as long as the genuine factory batteries. So I expect more of the same.

Still, at about half the price of a genuine Canon battery, these non-OEM may still be a decent value, especially for everyday, non-critical uses.

I may still decide to deduct star(s) for battery capacity after I have more experience using these K&F batteries. But so far they haven't given me any issues with my Canon EOS R7 mirrorless camera, for both still and video.

So for now I would like to give this product 5 stars.

On first attempt they don’t prompt the “battery not recognized” that some other 3rd party batteries do on my R6, so that’s promising. Whether they last as long as the OEM battery will remain to be seen. Not really sure in what situation I would need to use the USB-C port to charge these since I already have dual chargers, but maybe they would charge a little faster. I guess it’s nice to have in a pinch.

A two-pack for less than what Canon charges for a single LP-E6NH battery. That's a great value and both batteries are recognized as LP-E6NH units in the battery grips of an 5DII and EOS R. Both batteries are delivered with 90% charge and are ready to go. Both have worked great in the limited amount of time I've used them. Slightly larger listed capacity than the OEM batteries but we shall see how that translates in real life scenarios. Will update if anything changes.

I've been using these for about 6 months and absolutely love them. They seem to last as long as the OEM (I haven't done extensive testing, but they work well enough for me), and they don't require a bulky charging plate. These were a real boon for me when I was backpacking for 2 weeks this spring, highly recommend.

Bought two of these batteries and they seem to work perfectly in my Canon R7. The camera recognizes them as LP-E6NH same as the stock battery. No problem charging on the Canon charger either. Would buy again.
