Great customer support, fast replacement, and much better performance
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.
