Juicebox External Battery Kit for Blackmagic Pocket Cinema Camera (BMPCC) 4K, 6K, 6K Pro, and 6K G2

Works perfectly... no issues!

The media could not be loaded.  Disappointed because the lock is not fitting.. I have to exert extreme pressure to get the lock to SOMEWHAT wrap around the battery..Sucks because I need this for a wedding shoot come the 11th and if I return and reorder I’m not guaranteed to have a battery come wedding time.

This is great to use, it almost made the BMPCC 4K a run and gun, haha. And while this is a design flaw on BlackMagic, i did have some issues with the connection staying in on occasion, which gave me a great 15 minute panic on a shoot.I got it resolved but it definitely makes me a bit wary in the future.

It will stop working in a few months if you use black magic camera. Just go vmount.

The pack is a bit big. I like the hours of power it provides. A display on the pack shows percentage of remaining power.,

At first it charged and lasted. I was impressed. A few uses in and it will not charge at all. This happened with 3 seperate batterys.Pleaee do not let this happen ton you.

So, I got two juice boxes a while back. I didn't do any heavy use for them but, I did a couple of small projects. My plans got shut down by covid, death in the fam, and other things. I used both batteries on a trip to Albania for a documentary and all was good. I got back and put batteries away and I am gearing up for a shoot this weekend. As I am checking them I see a problem. One is totally dead and not taking a charge while the other is at 87%. I need to get another one now since I can't do anything without a backup but, I am very disappointed.

I bought 2 of these when I first got my bmpcc4k. They're still running and give me about 2.5 hours runtime. Love that they give me a full percentage readout of battery life. Also they charge super fast.The bad thing is the mounting option. The mount always has a little bit of wiggle. It's never tight. Also, it's glued on so the adhesive came off ib the heat on one of them. And on the other on it slowly slid crooked. I ended up taking the mounts off and crazy glued a solid quick release mount on. Worked like a charm.Overall good batteries but nowadays you can get more power for cheap with some vmount batteries. Many vmounts are even just as light and have readout displays too. Not to mention solid mounting.
