This 99Wh K&F Concept battery strikes a remarkable balance between power, portability, and versatility, making it ideal for power-hungry crews. After using it intensively for several days, here are my impressions.
The 6700mAh (14.8V) capacity provides approximately 2-3 hours of continuous power for a BMPCC 6K camera, which is ideal for shooting in locations where access to electricity is limited—though thankfully, we're reaching a point where such locations are becoming increasingly rare. The 100W bidirectional PD fast charging system is fantastic, allowing you to recharge the battery in approximately 110 minutes with a compatible charger, significantly faster than other V-mount batteries in this price range. This same feature allows you to use it as a power bank to charge devices like laptops, adding versatility to productions in remote locations where every mAh counts.
The build quality is robust, with fire-resistant materials and impact protection, although I think the V-Mount locking mechanism could be a bit more secure, as it has a slight wobble when used with some third-party mounts. The ports are well laid out and easily accessible, with the two D-TAP ports conveniently located for accessories like monitors and LED lights. The digital display showing the remaining charge percentage is accurate and visible even in direct sunlight, a significant improvement over the basic LED indicators on other batteries.
Weighing in at 525 grams, it's quite manageable for its performance, maintaining a good balance with lightweight camera setups like my Sony FX3. The air transport certification (<100Wh) is crucial for productions that require frequent travel, avoiding complications with airlines (in case you were wondering about the 99Wh rating).
The BMS (Battery Management System) protections work correctly, and I've noticed that the battery maintains reasonable operating temperatures even under demanding loads, such as simultaneously powering a camera and an external monitor, all in a hot and humid environment like we've been experiencing lately.
While it doesn't reach the extreme capacity and runtime of premium options like Anton Bauer, it's a good choice.
