K&F Concept 99Wh V-Mount Battery with PD100W USB-C Fast Charging and Multi-Output Ports, TFT Digital Screen & Emergency Light for Camera, photography light, smartphone, laptop etc.

I never thought about getting a V-mount battery when I had my Canon R5 camera. I took mainly pictures and when I did do videos the camera would overheat before I would get through one battery so I never got to the point of needing more energy. Then I upgraded to the R5C and started actually more videography at 4k60p RAW and realized after the first 20 minutes that regular LP-E6NH batteries would not cut it anymore and hence finally purchasing a decent V-mount battery and at the price point to power storage this K&F Concept 99Wh fast charging battery caught my attention. I'm never going back to standard batteries for videography again.

Attached to a SmallRig V-mount battery holder, I now have enough power storage to run an external monitor and my camera in video recording at 4K60P RAW for hours. It's plenty of energy to last for my personal tasks. It is also on the smaller size compared to other batteries in the same size and it doesn't weigh that much. The main two outputs I use are the two USB-C ones. That's what my camera needs for power and what the Viltrox external monitor takes also. A lot of V-mount batteries only have one USB-C (if any at all) output so this one having 2 got my attention and I'm glad I chose this one. I can charge my phone if necessary also (dual function of a battery of this size). If you're going to do videography, I absolutely recommend a V-mount battery and this K&F Concept one with a nice LCD screen that gives you output and input data on the screen is definitely a great buy.

I bought this battery about two months ago to use with my Sony FX6, and I’ve been very happy with it. One of the main reasons I chose this model was the range of output ports — USB-A, 2 USB-C, DC, and D-Tap — exactly what I needed for my setup.

To be honest, I’ve worked with batteries from other brands too, and for the price, this one holds up surprisingly well. On a full charge, it powers my camera for a solid 5–6 hours with no issues.

It also charges relatively fast, and I haven't run into any problems so far. The design is sleek, durable, and feels premium in hand.

Overall, I’m very satisfied and will definitely be buying another one!

This V mount battery has proven to be an exceptionally valuable addition to my filmmaking equipment, offering a compelling combination of performance and affordability. Its price point is remarkably competitive, especially considering the features and capacity it provides.

One of its key strengths is its ability to hold a charge effectively, ensuring reliable power delivery throughout extended shooting sessions. It consistently powers my devices as expected, without any noticeable fluctuations or interruptions. While I lack the specialized equipment to conduct precise capacity measurements (and it's a common observation that many power banks and batteries don't quite meet their advertised specifications), my practical experience of charging my devices multiple times suggests that its actual capacity is very close to the stated amount. This reliability is crucial for professional applications where consistent power is essential.

The battery's form factor is another significant advantage. It's designed to be compact and lightweight relative to its capacity, making it conveniently portable and easy to transport to various filming locations. This portability is vital for on-location shoots where minimizing equipment weight is paramount. Despite its lightweight nature, the battery exhibits a substantial and robust build quality, instilling confidence in its durability and resistance to damage.

The charging time is somewhat longer than with smaller batteries, but this is an acceptable trade-off for the extended runtime it offers. The integrated display is a particularly helpful feature, providing real-time information such as voltage output, which is invaluable for monitoring the battery's performance and ensuring compatibility with different devices.

I've relied on this battery extensively for powering my camera and other gear during filming projects, and it has consistently performed admirably.

In conclusion, I wholeheartedly recommend this V mount battery as a reliable and cost-effective solution for powering professional video equipment. Its combination of strong charge retention, efficient power delivery, portability, durable construction, and informative display makes it a worthwhile investment for any filmmaker or videographer.

I got this battery as backup power mainly for my video lights, but I’ve used it with other equipment, as well. It works great. It charges up easily and lasts a long time. I’ve had no issues while in use. I like that it is V-mount because I can hang it on a light stand using a V-mount hanger and not have cords to trip over. It is built sturdy and feels durable. I’ve experienced no heat issues. The display is easy to read.

I started of my V-Mount journey with a larger (dimensions) Neewer V-Mount with many ports but only one USB-C. I've now relegated that one to powering my portable key light. This battery is so nice, works well, is smaller with the same capacity, and has two USB-C ports.
I'm trying to think of anything I won't be able to power on a run-and-gun rig. I'm currently powering a Sony ZV-E1, Viltrox D550 Pro external monitor, Ulanzi CU01 Thermostatic (new) fan cooler on low, and a wireless mic receiver. I just finished 5 hrs and and it still had 20% left.

I shoot video mainly with my phone for interviews, but I also have a Blackmagic Cinema 4K and a Sony a7 iii that I use for video. I got tired of small batteries, and decided to look for a single larger battery I could mount to my tripod and run a cord for D-Tap to the camera.
This K&F Concept 99Wh Battery is a great find!
It uses a mini V-Mount plate on the back so I can clip it to a pipe/tripod leg mount securely and quickly. I have access to a D-Tap plug as well as USB-A and USB-C, and a DC out connector. Running a line up to my camera is simple and safe.
This supplies 99WH, which means you can take it on airlines in your carry-on bag. I made a copy of the instructions to bring with me just in case TSA wants to double-check the power rating.
I really like the clean display. I can check overall power percentage, and also get a breakdown of current draw across the DC and USB plugs if I have my phone or mics charging on the battery.
This has lasted me about 6 hrs, running my Sony and a light kit; I haven't shot as much as I had planned this past month, but I'm really liking this so far.
This K&F Battery is a great size. This is so designed for a travel bag there is no excuse not to take it with you!

I've been using this battery from K&F for a couple months and I've been really happy with the experience. The battery has really solid construction as well as a bright and reasonably large display. On the back you have the classic V-mount with charging pins that are typical for V-mounts. Truth be told, I think I charged it with these once and used USB-C the rest of the time. There is also a very small light, more on this later.

One side has a power button that if you tap once, you get a quick display of charge status. Pressing and holding will get you a more informative display for charging status that includes the ports and their output. as well as a very useful. When in this configuration, the little light will turn on and give you just enough light to do simple tasks in the dark.

On the other side is a D-tap port with a rubber cover and on the top are the remaining ports are along the top of the battery.

The battery really does deliver as a smaller sized, on the go option to keep your lower power gear running. Great for auxiliary lights and other random pieces of kit you run day to day. I was even able to power a motorized slider with the DC port. All in all, I'm really pleased with the battery and hope it can be cycled and last a long time. Well done!

Well built, works great ,last long, good quality , what more can I say other than I just bought 4 more. Worth every red penny.

Working great on my FX3 cinema setup. The form factor is great. 99Wh is perfect for travel on airplanes. In addition, the actual shape, being a near perfect rectangle makes it fit very nice along other rig components and also allows it to fit in padded bags and foam cases easily.

The outputs are numerous and have been working well for a variety of accessories. The screen on the back has better resolution than my first 2 cellphones hahaha. Seems like overkill but it's useful for long takes when estimating your battery life.

Best part is probably the metal build. This battery is heavier than it could be if it was plastic but it feels like a tank. Very robust.
No faults thus far

A lot of power in a small footprint.
What I think that could be improved is to have 2 D-TAP connectors instead of one but for the rest I like what they are delivering with this product.
I added images comparing with a Neewer and one generic with no name.
