Picked up this 2-pack of NP-F970 batteries for my camera and lighting setup, and they’re exactly what I needed! These things are a solid upgrade over the smaller batteries I was using, giving me a much longer shoot time without constantly swapping or charging. Plus, they're compatible with so many different pieces of gear, which makes them super versatile. Slapped them on my camera rig, and it just kept going—barely made a dent in the power after hours of filming.
The real bonus here is using them with my lights. They power up my LED panels like champs, which is great for long shoots without access to outlets. No more stopping mid-shoot to scramble for a recharge! These batteries feel solid and come with a huge charge capacity and a nice charger, so I don’t have to worry about running out of juice when I need it most.

These batteries, designed to power a Wi-Fi video transmission receiver, seem to be well made. We'll see later.

I have been gearing up my little in-home studio, and using multiple cameras means I have multiple monitors and lights going...so I needed some more power...but I wanted it to be mobile gear as adventure season approaches (winter where I live)...so settled mostly on NP-F batteries. I tried a couple off-brand ones to save money, but that didn't go well, so when I saw K&F had this 2 batteries w/charger kit for a good price, thought I'd give it a try...

- I used one in my largest screen field monitor, and one in a setup that utilizes an iPad as a cordless monitor. Both discharged at the same rate as my most expensive batteries, and worked particularly well with the iPad, even charging it all the way up while the screen and app were in use.
- charging time took longer than discharge on the iPad setup, but I am fairly certain that is due to the brick I used...a lower power one as I wanted to see how long it would take with a standard style, unknown spec (just in cases) charging brick.
- charger is lightweight, but has nice bright led indicators, though it does not display progress...only charging and fully charged...which is fine, but a progress meter would have been nice
- build quality is nice, pretty indistinguishable from the nice NP-F's I already had

Overall these seem to be great batteries at a very affordable price, and are an excellent addition to my budget friendly studio setup. Would happily get them again, and recommend.

I was a bit iffy at first cause I know K&F does lots of lens filters, but honestly these batteries are awesome!! They hold charge perfectly! 5/5 stars

These batteries have been dependable for long shoots and extended use. Charging them is efficient, and they hold their charge well, providing enough power to get through a day’s work. The LED charger is a helpful feature, making it easy to monitor the charging process. No overheating issues, and they work perfectly with my equipment.

I have two LED lights that work on NPF batteries and these were able to keep my light on for just about 3 hours at 100 percent intensity on my night doc shoot. The charger comes with a cable, but not a block, so there’s that to keep in mind, but I already a charging station set up and so that was not an issue for me. It’s also great to have a smaller charger for travel purposes.

These batteries are solid and keep my gear powered up for hours, which is a big win when I’m filming or using my lights. The dual charging setup is a nice touch, and I like that it charges over USB, making it convenient to plug in almost anywhere.

Charging speed, though, could be faster—these take a while to fully recharge. The charger’s basic LED indicators are useful but not very detailed. If fast recharges aren’t critical, these are a great option that does the job reliably.

Finding reliable power sources for my equipment has always been a bit hit or miss, but these K&F Concept NP-F970 compatible batteries have been a solid choice. I needed dependable batteries for my video light panels and my field monitor while working from home and for outdoor shoots. Both batteries offer an excellent capacity, running my gear for hours without interruptions. One time, I used a battery to power my 20-watt video light for over three hours, which was quite surprising.

The inclusion of a dual USB charger is a nice touch, even though it charges a bit slowly. Overnight charging sorts that out for me since I can just plug them in before bed. I do wish the batteries had an onboard power indicator for ease of use, but that’s a minor issue considering their performance. Also, the charger’s imbalance when both batteries are inserted is noticeable but not a major problem for me.

In terms of design, they fit my devices without any hassle and performed on par with more expensive, branded options. I was initially sceptical given K&F’s primary reputation for other types of accessories, but these batteries have proved to be reliable, cost-effective additions to my kit. Whether I’m in my home studio or enjoying a scenic hike while capturing footage, these batteries ensure my gear stays powered.

The batteries worked perfectly. No issues with it. The charger also worked fine: it uses USB which is convenient and it worked well.
