I tested the K&F CONCEPT KF-V99 SE V-mount battery in my video equipment. Its 99Wh (6700mAh) capacity is ideal, as it often meets airline regulations while still providing long runtimes for cameras or video lights.
The wide range of ports is particularly noteworthy, including dual D-TAP, USB-A, DC, and a powerful USB-C port with 100W PD fast charging. This makes the battery extremely versatile and eliminates the need for multiple chargers.
The integrated TFT display is very useful, providing a precise indication of the remaining runtime and charge level. The battery is robustly built and fits securely in the V-mount. The additional function as an emergency light is a practical bonus. Overall, this is a high-quality and reliable battery for professional productions.

I ordered two of these V-mounts, but one was unfortunately defective (manufacturing errors can always happen!). After contacting the manufacturer, a replacement was immediately offered and promptly delivered!
The service here is truly outstanding! Many thanks to K&F!
I now own five V-mounts from K&F and am extremely satisfied – the price-performance ratio is unbeatable!

My first K&F Concept KF-V99 SE V-Mount battery had several issues — it overheated during 100W PD charging, the capacity tested lower than expected, and the indicator wasn’t very accurate. I thought I had to return it for a refund.
However, I was contacted by a very professional and friendly customer support agent, who handled the situation exceptionally well. They offered a replacement right away, and the shipping was fast.
The replacement battery performs much better than the first one. No overheating, more stable output, and overall it feels like the battery I originally expected. I’m honestly thinking the first unit was just a lemon — it happens.
Overall: great support, quick resolution, and the second battery works as it should. I appreciate the way the company handled everything.

A great, efficient, compact, and very economical V-Mount battery. I previously owned a higher-end model and I like this one even more. The only thing missing is accurate charge status monitoring.

This is yet another excellent product from K&F CONCPT. This mobile charging station is no exception with all the ports and IO you would need to bring backup power to any remote location. The 6700mAh 100W PD with fast charing capability is a great addition to you're on the go gig bag.
The build:
Although this unit is primarily made of plastic polymer it offers a surprisingly heavy duty outer shell that seams shock and drop resistant. All ports are covered in a removable rubber gasket that protects them from the elements. Sadly there is no led monitoring screen on this version. The V mount plate is well designed, Yet might not fit on all bracketing systems. Since the IO is all situated at the bottom of the unit. All ports are well seated and feature stable and reliable connection. This model also features heat dissipating fins on the back of the unit. Offering great thermal management when in use. This also applies to it's charging cycle helping it stay cool insuring longer and more stable battery life.
The ports:
x2 D-TAP
USB-C
USB-A,
12V (5.5x2.5mm), BP,
charging protocols:
PD3.0, QC2.0, QC3.0, PPS, AFC, FCP, SCP, and DCP-1.5A, compatible with APPLE-2.4A and more fast charging protocols.
Security features:
Proudly certified by CE/UKCA/PSE/RCM, this V mount battery features an intelligent battery management system (BMS) that automatically protects against short circuits, over voltage, over current, overcharging, and over discharge, and even sends timely alerts in case of over power, over current, over voltage, over temperature, and under power discharge. The fireproof PC V0 shell for enhanced safety and durability is yet another great safety feature insuring you're gear will function as intended without damage.
Charging times:
This uint will charge from around 20% to full in little as 3 hours when using the USB-c port. If you can afford 2 of these units you will be able to run you're camera alongside many accessories for a full 9 hour day with no issues.
Things to note:
All the power delivery options are situated on the bottom of the unit. This might seam like a good idea, at first glance. Yet you will run into issues, accessing different ports. Depending on you're V mount plate and it's relative depth. This is one of the reason I've deducted one star of the final score.
Final thoughts: 4 out of 5
A compact and portable product that offers a good amount of charging power in a small form factor. With it's versatile port selection and fast charging speed. This will be you're best friend on those remote location jobs that require lots of extra gear. A good value proposition, for you're hard earned dollar on the market at the moment. Other companies come close but don't offer as much in terms of IO or power delivery. So this unit manages to fly above the competition not buy much. The only thing that's missing is the LED screen, that many other brands offer. To bring it up to par with it's competitors. This is ware in my opinion they have cut costs to pass it on to the consumer.
