I’m using these in constant lights. I like that you get two batteries since when I’m using constant lights, I typically use them in sets of two. Everything worked fine with the batteries. They charge up in a reasonable amount of time and last similar to other batteries I have of the same size. I noticed no problems like excessive heat or a drop in power. I like that they come with a charger. I’ve cycled through them multiple time. Good batteries.

K&F is a brand I have come to trust for all my photography-related purchases, and these batteries did not disappoint!
For the price it is remarkable that they provide 2 batteries, and a quality charger - I have no idea how they do it.
I'm using this on an LED smart panel and it totally transforms what I can do with it. For only $30 at the time of writing. I couldn't afford to buy 'name brand' batteries, and there are so many other brands out there whose quality I don't exactly trust. K&N has delivered again with a great product that lives up to my expectations.
Do not hesitate on this battery kit.

I oftentimes use NP-F batteries to power continuous lights and external monitors.
I happened to need more than usual for an upcoming filming session, so I got these.
They work great so far in my testing.
Build quality is standard, but good nonetheless.
The included charger and USB-C cable are handy in case that you didn't have either previously.
This is a pretty good, standard kit. I recommend it.

I've always been happy with the K&F products I've purchased over the years, and these batteries are no exception.
They feel high quality and the charger works well. Speaking of the charger, I love that they flipped the pins upward. At first I didn't know if I'd like the change since all of my other chargers have you slide the batteries in, but I like it so much better. It somehow feels more stable and I'm more confident with the connection. The charging pins are also solid instead of the slotted ones you normally see so that makes me feel much more confident in their sturdiness.
The cherry on top: the price is really affordable. Great job K&F, and keep up the great work!

K&F once again delivers a great product at a affordable price. Got these for a couple of photography lights I use, and wanted to use them wirelessly and these batteries makes it possible for me to do so. Battery life is great and within expected reasons. Charger does a good job of recharging quickly. Overall, I have no complaints for these...they work and do what I need.

The batteries work great, I am using them in video lights. They power the lights great and for an adequate time. They are on the small side but it's giving an appropriate run time in a small and convenient package. My long runs stick out very far. The charger works great and charges quickly.

This charger and battery set works great. The batteries fit the NP-Fxxx accessories just fine. And the charger is compact and small for easy packing. The charger also has both USB micro and USB C ports for power in.

Standard NP-F series batteries. its on the lower end of mAh but they work great for monitors and other camera gear (in my case) that uses NP-F batteries. Come with a dual slot charger which works just fine plugged in through USB. I can never have too many of these and this is a great set for a good price for the batteries from a company that you can trust

These F550s power my camera monitor just fine. For more power hungry items like high wattage lights, they only power to 60%, but again, work great for my 6 inch monitor.

I use these batteries for monitors and lights when I'm filming. The 550's are good for about 3 hours on a monitor and are much lighter than the 750's I have (that are double the size/charge). Fortunately, this also means they charge faster.
I do wish the charger was a fast charger, but it's USB, not direct plug, so it can only supply so much power. The charging base is small enough to fit with my gear and has USB-C and micro (anyone use micro anymore?). The only downside to the charger is that it displaysonly charging and full, it doesn't let you know how far along they are (like 3-bars, for example). When I'm at a shoot, sometimes it's useful to know if the battery is almost full, and with this charger, I have to guess. I've also found that if I take a full battery off the charger for a minute, when I put it back on, it'll charge for another 5-10 minutes. I don't know what's happening, if it takes that long to tell it's full or what, but it makes me wonder if it's underfilling the batteries for some reason (poor design, safety, or some other reason).
So far the batteries charge quick and work well. They clip in easily.
