I must buy a battery bracket for my BMCC but i don't know which
I have found:
Bebob COCO - http://www.bebob.de/Akkus-und-Ladegeraete/COCO-15V-II.html
and
Movcam - http://www.creativevideo.co.uk/index.php?t=product/movcam_306-0209 or http://www.creativevideo.co.uk/index.php?t=product/movcam_306-0208

Please help

All of those would work. You just need the correct cable.

this one i have. built really well.

I am using the COCO from Bebob, really great solid piece bracket, you can mount it in various positions too

I second the Bebob COCO adapter.. It is very lightweight and very well built. Here is some pictures of mine with the 12V Coco Adapter Cable for Black Magic

John Brawley was talking about it in the other forum

The Bebob battery system is very cool. On their batteries there is a vast improvement to the D-Tap plug, which I think they call "Double D" What this means is that you can plug a single D tap plug into the battery in two different positions. The plug takes care of the polarity. The idea is that with a right angle Dtap plug you can choose which way to have the cable run away from the battery. So each battery has one of these plugs AND there's also one on their mounting plate.
ON the mounting plate itself there are 4 Hirose plugs, so you can wire up a power feed to any of those as well. So in theory you can power 6 different accessories.
The battery runs the camera for about 3 hours without running anything else.
The only thing I don't love about the battery is the rail mounting system. You can mount it above or below the screen, but it kind of can get in the way of seeing or operating / touching the screen. I'd really like to see a side mount, a bit like the ET system that was developed for RED. Bebob tell me they're working on something like this and should have it ready to go soon. Perhaps ask if you're about to buy and maybe you can consider getting one of those instead.

Bebob Coco II has 2 - 12V and 2 - 7.2V input and double d-tap? i can plug d-tap directly to Coco?

Yes you can.. there is a D-Tap plug on the adapter.. and the bebob battery has a D-Tap plug on it too.. so you will have two D-Tap plugs one on the adapter and one on the battery, both are double d-tap

and there is a switch on the adapter.. I asked Bebob about it and the four outputs, here is what Pierre Boudard from bebob told me;

each of the 4 sockets you see on the picture (Hirose 4 Pin connectors) are wired with:

Pin 1: Ground
Pin 3: 7,6 or 8,4V depending on the switch position
Pin 4: Battery voltage (means more or less 14,8V)

This means that on every Hirose Socket you have both Voltages, Battery voltage and converted voltage. Depending which pin you wire on you cable, you grab one or the other voltage.

Reason for the swith: the Blcak Magic camera accept more or less any voltage. But other camera not. For instance, Some Sony cameras needs exact 7,6V, other need exact 8,4V. Depending on the camera you are powering with the COC, you can then select the converted voltage.

ok. i must buy a coco II and Bebob battery - for example: http://www.bebob.de/Akkus-und-Ladegeraete/V75.html

How long can i use camera with this external battery (plus 1.5-2h with battery on cam)?

if i am not mistaken the power consumption from the camera is 18w.. so 75wh battery will give you approximately about 4 hours.. plus you have the internal battery that runs for 1.5 hours

if you are ordering the adapter from Bebob, don't forget to ask them for the Adapter Cable for the Blackmagic camera
