A truly exceptional energy source suitable for professional use thanks to its large capacity, stability and ability to adapt to various uses and uses. Inside the package, in addition to the battery, there is only a USB-C charging cable and a multilingual user manual. The battery, as you can imagine, is generous in size and weight, this to justify the enormous capacity and great efficiency of this energy source. We are in fact talking about a capacity of 6700 mAh and a maximum voltage of 14.8V with a maximum power of 99Wh. The 100W fast charge is bidirectional via the USB-C connector n°1 present on the upper part together with three other connectors: one DC at 12V, another type C with a maximum power of 65W, one USB type A and finally a D-Tap connector on the side. At the bottom, however, there are the BP electrodes. The battery has a very solid structure and is certainly resistant to shocks. Thanks to the rear clip, the battery can be easily connected to a video camera or camera to provide continuous energy during operation or to recharge one or more devices at the same time, even quickly. On the front there is a color display that indicates first of all the residual charge status in percentage and further down the four positions of the four inputs with indication of voltage and amperage used for each connector. This ensures that you can always have a clear idea of ​​the residual autonomy that you can rely on. The thing that I noticed that convinced me a lot is the fact that the battery remains constant in its work until it reaches zero. Let me explain better: it often happens that power banks and similar below 10% of autonomy suddenly lose the residual charge making them unreliable. This battery remains constant in the supply of energy until the last drop of charge! This allows you to make an accurate estimate of how much time we have left.

I could honestly not be more impressed with this V-Mount battery from the always excellent K&F Concept (one of my favourite brands)

This is a beautiful looking V-Mount battery and whilst looks aren't the most important thing here you have to admit this one is an absolute stunner.

As far as connectivity goes this one does the lot, from D-Tap, Barrel Output, USB and USB-C so you can get stuck in and get your devices powered up from one battery when shooting which is the absolute ideal scenario.

It feels extremely well built and will obviously last a lifetime. The layout is logical too which you can't say the same about for other brands.

The connectivity is on the top of the V-Mount battery which makes connecting up whilst in the middle of a shoot extremely easy.

The digital screen though. That's such a great addition and you can see the power draw as you're going so you know when you need to recharge but with a battery with as much capacity and staying power as this one you should easily be able to go hours/full days depending on what you're powering up.

I'm using mine with my Sony FX3, a monitor and other accessories that I have running into it. I'm not using the D-Tap as a simple USB-C connection is perfect for my needs anyway.

It has a 100W PD power output which is remarkable, and even has a tiny torchlight built into it on the back where the V-Mount connection is! That's strangely a very very useful addition and I've already used it numerous times for helping see in challenging lighting conditions.

K&F Concept are now a premium brand in videography and photography and I've got to the stage where I trust their products implicitly before buying but it's always good to get them in your hand, test and use them, and confirm it for yourself that they've done it yet again.

What a great solid, brilliant and almost futuristic V-Mount this is. I shouldn't be this happy about just a battery but this one makes me smile a lot!

As far as VMount batteries go, I have a new winner for looks and function.

This is my fourth VMount battery and I am actually surprised by the little thoughts that have gone into the look and feel of it. From the fancy little animation of the LED screen, to the aluminium housing around the edges. This all screams of a premium product, which you do expect from K&F nowadays.

You get your regular outputs, USB, USB-C, DTap and a barrel output.

100W PD output is wonderful, normally these batteries will cap out at 65W.

I actually found the little torch light by mistake when I was playing with the power button. Just press and hold it and it'll fire up. Absolutely required in a dark studio when clamping your battery to the mount.

Fantastic battery I use for heavy videography work when travelling. This provides ALL DAY power, supports multiple charging, powers by power-hungry Canon cinema camera flawlessly, and just tends to last forever. It is heavy, as all 100 batteries are (I use the Neewer 50 battery more regularly, which is also great) - but this is the one I go to when I just can't afford to run out of power no matter what. Much cheaper than comparable alternatives.

I couldn't live without V mount batteries these days, well I could but it would be much less pleasurable, and this example from K&F is up there with the best having a large capacity and a plethora of outputs.
Whilst my main use is to power cameras, monitors and studio lights - as seen here - via dummy batteries, this also makes an excellent emergency power bank and is capable of reviving everything up to and including a laptop.

I did receive this for free via the Amazon Vine program but will be ordering a second as I'm that impressed.

K&F Concept’s 99Wh V-Mount Battery with PD100W

The K&F Concept’s 99Wh V-mount battery is a versatile V-Mount battery with 6700mAh of capacity. It weights in just under 635grams. It’s a flexible battery offering charging dtap or usb-c charging. It takes advantage of high-power USB-C power sources, charging up at 16v/ 5a from my power bank for 80w of charging, from a wall socket the built-in screen suggested it was charging around 99w. Using USB-C it was charged in around 2 hours. This is a great advantage over older dtap only batteries – if you are around a high power dtap charger use it – but a good USB-C wall charger can potentially charge two batteries at once; and is much more compact than my dtap power brick. Using USB-C also needs less kit in my bag’ I always carry a few USB-C cables and most of my other kit charges up from usb-c too. K&F include a good 240w rated usb-c cable in the box.

Regardless of the charging source the screen shows a clear display of the state of the battery charge and lets you know which of the various outputs are discharging when its charged. When charging there is an accurate time estimate to charging being complete. When using a high-power source, the battery does get warm whilst charging.

Power output the flexibility continues; you can run use the vmount port and the BP ports will power your device happily. I have used it in a loop for the last few days running a large LED fill light for the last few days. The screen on the battery shows the drain as 70Watts (the panel of the light says it’s a 70w light, so the meter is accurate.) I found the VB99 lasted a little over 2 1/4 hours constant running on that light. The light runtime is on the higher end for my vmount– if you are shooting off grid this will keep a low power camera rig going for a long while.

If the battery is flat when you need it, you can use the light in an adhoc UPS mode charging and running at the same time; just make sure your input power is greater than the output. Running the light and charging from the same wall adaptor; it added an hour to the charge time which is a good compromise.

Besides the vmount port the battery gives you a 12-volt DC connector; a pair of USB-C’s and a usb-a. Total output is limited to 100watts. I could run the light and power a camera via a usb-c cable at the same time. The batteries usb sockets all sit behind a weather flap; that I found difficult to open with my trimmed nails.

When in use the screen is usually off; there is a button on the side that will let you check the status. You can long press that button to turn on a small light in the back of the battery which is useful for lining it up with a mount in low light; you do need to turn it off again – and the screen doesn’t warn you it’s on. It’s a great idea the UI should warn you it’s on; or it should power off when connected to a vmount.

The manual says the screen face is scratch resistant; time will tell on that. The surround of the battery is metal; which should help keep some heat down in charging; and especially surprising given the relatively low weight – it’s almost 150g lighter than my next lightest 99Wh vmount.
K&F have been on a roll with quality products recently; this vmount filter is another sign they are coming for the professional market.

Please see attached video review for unboxing and initial assessment. The product charged easily via USBc. I did not realize that this battery is designed for certain types of cameras - ultimately I found someone with access to that type of device and it worked flawlessly. It also charges other devices without issue and very quickly. No reservations recommending this product.

This battery is an absolute beast. It has several ports to run different accessories at the same time, and is perfect for all of my particular needs. As a matter of fact, if I'm being honest, it's almost too good for what I need. I'm not complaining though, because I know that I'll never have an issue with powering my lights, my video monitor, and even my camera with a dummy battery if I choose to. I use the D-tap for my camera monitor, while using both USB C's to run a light, and sometimes my camera. This is all done simultaneously, and easily monitorable from the display on the battery itself, where you can see the power output for each device. It has USB-C fast charging, and a pretty robust 6700 MHz capacity. It'll have no problem powering professional lighting equipment, professional video monitoring equipment, cameras, acting as a power bank if need be, and many other applications where power is needed. It's extremely versatile with a range of inputs, and nicely designed. The screen is color and easy to read, and gives you a great knowledge of your power drain. All in all, it's a fantastic V mount battery, and I would absolutely recommend it for professional videographers, and photographers. I usually find at least one or two bad things to say about a product, but I'm struggling to think of any in this case. It's an easy five stars.

Amazing battery. Last very long with the video equipment I have.

The battery does what it's supposed to and charges devices that take usb-c, usb-a, d-tap, and 12v barrel connections. I really like the 240w cable they included (usb-c to usb-c) that includes a strap to keep it nice and tidy when not in use. I also like how there is a light on the back that you can turn on/off by holding down the power button for 3 seconds. I haven't seen this feature on a v-mount battery yet, so it's pretty neat to see them trying something new. The gun metal gray sides look pretty stellar as well and give the battery a nice look that's also different than the rest.

The only things I don't really fancy too much are the display readout and the main plug cover. The cover is a little difficult to get off of the plugs and then it just is in the way when you are trying to access the plugs beneath it. Perhaps this will get easier with use, but as of now it's a bit tricky. As far as the display goes, it feels outdated with large blocky text and doesn't display the readouts in real-time. I am glad it shows the voltage and wattage the port is using though.

All in all, this is a good battery, and I can recommend it.
