Kastar NP-F580 Battery 7.4V 3500mAh Replacement for Blackmagic Design NP-F570 Battery, Blackmagic Design Pocket Cinema Camera 6K Pro, Blackmagic Design Pocket Cinema Camera 6K G2 (4-Pack)

Lasts longer than the original battery.

Got these because I saw a guy on Blackmagic's website forum saying he was getting a little over 3 hours of record time with these in his battery grip. I've used several other batteries and have not gotten close to three hours so I had to try them. Took about 4 hours to charge them. Put one in the camera and the other two in the grip and exactly what he said. 3 hours 16 minutes and 42 sec with one press of the record button and let it run untill it died! This is now my official battery for all my 6k and 6kG2 cameras. And anything else that uses this type of battery!

Good batteries but do not last as long as the originals by a slight slight margin. Will allow you to shoot any which way you wish and work just like the stock ones.

Using these on my BM 6K FF in a studio/indoor scenario and they are doing a good job so far. They do definitely last more than the original BM battery, which is ridiculous. Between these 3 and the BM I can now carry on with my shooting without plugging power. Totally worthy.

Using underpowered batteries in my BMPCC-6K Pro was a major pain during a documentary shoot. Sure, I could use V-mount batteries, but it makes the camera rig heavy on an all day “run-&-gun” production. With these internal batteries, my rig is light and I can get almost 2-hours each when shooting with these batteries (turning the camera off during resets, of course). Using the battery that came with my camera and the additional 4 purchased here, that’s 8 to 10 hours of run-time per day! With a multi-charger, I can shoot all day & recharge at night my, and i’m ready for the next day’s shoot. Best purchase I made for my documentary!

Brand new out of the package, the battery got stuck in my bmpcc 6k pro. Had to use excessive force and tools to get the battery out. It's just barely too big. Maybe some people will have luck with these but the manufacturing tolerances are probably not what they're supposed to be so there may be deviation from battery to battery. I bought two and they were both too big. Per the description they were supposed to fit my camera. Also, the batteries weren't swollen. When compared to another battery I have that fits these are just a hair longer. I never write reviews but thought maybe I could save other people from dealing with this.

Duración excelente

Needed more batteries for my BMPCC 6K and these were the best option. They hold a charge and were super useful for me on long shoots. I am planning on buying more so I can get through longer shoots. Would recommend.
