These are great backup batteries for your DJI Osmo Action 3, 4, or 5. I tested it on my Action 4 and was very happy with the performance. I tested the batteries recording constantly to see how long they would last compared to the OEM DJI battery. On both, I got over 2 hours of steady recording on each using the 4K30/RS+ mode. The K&F battery actually lasted nearly 2 minutes longer (1.6% longer) which is nice. It wasn't very scientific but it gives me good confidence these batteries can be relied upon when you need them to work. I have bought other K&F products before and they're a great reliable brand.
The kit includes 3 batteries and a charging hub. I also test charged both the DJI battery and the K&F batteries and they both work just fine with the supplied charger.
I bought these batteries because I didn't have any backups for my Action 4 camera and I was pleasantly surprised. This is a really great charging kit that's significantly cheaper than the original DJI at US$29 each vs. K&F at US$45.99 for the entire set.

Haven’t used them a lot but they seem to be good, just one problem it that sometimes they charge until 57-58% only. The size is as same as the original ones and quality is good

The batteries and charger all perform as expected. The charger is more of a keep at home on a table or shelf type than the small throw in a bag kind I normally order. The cable is of a sufficient length to plug in the charger at a convenient location. The only charge indicator is a green or red light unfortunately but for this type I suppose that's really all you require. You'll have batteries charged and see they are at a glance. I don't think it feels flimsy and the batteries seem to have the same life as the originals.

These batteries are every bit as good as the factory batteries in performance, no error codes and lasted about the same as factory, but I find this charger to be even better than the factory becasue of its lower profile and I can remove the batteries easily without having to use the little tabs that are tough for big hands. I especially like the "5" being clearly marked on the battery as I have multiple action cams and often mix up GoPro and Action batteries if I'm not careful, these batteries are now my go-to batteries.

Perfect! Works great and the camera reads the battery no problem! Works as well as OEM and so far no issues. The base charger does seem a little on the cheaper end. I wish it was an enclosed charger with a closed lid, like so many others, that makes it easily transportable. But for the value, it's a small inconvenience. Overall love it!

Charger is small and compact.
Charges all 3 batteries at the same time via USB C power.
All batteries works fine on my Action 4.
Excellent value for 3 batteries and a charger.
Like other K&F product, this is excellent buy.

This K& F Concept Osmo Action 5 Pro 3 pack Battery and usb-c Charger is a good value solution to extend the life of the action camera. The charger works on mains and high-powered power banks charging the batteries in a few hours.
When you put a battery into the charger an LED goes red to show its charging. It goes green after some time. You would think at that point its charged; except I have taken original and one of these K&F batteries off when the green led was on; that my action pro 5 shows as around 60% (The original was 58 % and the K&F 63%.)
Putting them back on charge they were charged up to 100% an hour later.
The K&F battery life is comparable to the original I was able to an average record time at 4k120FPS close to 45 minutes with the batteries before they ran out. With the charge time and 4 batteries you can with suitable charging record almost constantly always having a charged battery.

I've been very pleased with the various K & F Concept products I've ordered and this battery and charger set lives up to the quality expectations I had. They charge as quickly as the OEM for my DJI Osmo Action 4. Appear to last as long, also. The camera has no problem recognizing them. Very convenient to be able to charge three at once and leave with backups for a long day. The charging cord is standard USB-C so no worries if it's misplaced.
