I bought 4 of these. 2 had problems after 2 month only. 1 does not charge. The other one does not hold charge.
Edit ; customer service reached out to me and replaced the defective units with brand new ones. Great customer support

Works well and is a bargain for the price. Keeps my R5C running just under 8 hours with it on continuously. Dipping into the menu to save battery instead of turning the camera off. Matches another battery I have so seems to be about right for 99wh

Impeccable, solid power.
The inclusion of special cables would have been great. But otherwise, 5 stars for the honesty

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.
