This battery is a great backup power source for my cinema camera .Thanks to my knowledge gained in practice I've found this battery to be reliable and long-lasting. It's GREAT for on-location shoots where power might not be readily available..
Pros
Reliable, long-lasting power source for cinema cameras
As my tests showed this battery pack provided consistent power to my Blackmagic cinema camera throughout the whole shoot without any interruption. Its compact, lightweight DESIGN makes it easy to transport and it has a capacity of 150Wh. My only issue is that it's quite pricey compared to other third-party battery options available on the market..
Pros
Long-lasting battery life for extended shoot times.
Cons
The battery is expensive compared to other options on the market.
terrible product. The cable wore out in less than a week. Also hardly suitable for Blackmagic 4K, because you get a cheap adapter. I do not understand it. Keep in mind!
