View Full Version : Powering the Blackmagic Design Cinema in the field via AC adapter / External Battery

After looking at all the specs, the main issue we will have is powering the Blackmagic Cinema Camera out in the field. Most shoots I been on end up lasting more than 90 minutes so having a built in battery is not going to work. Hard to believe they went this route in the 1st place.

Specs specify
Battery Life: Approximately 90 minutes w/ Integrated Lithium-ion Polymer rechargeable battery
Connections: 12~30 VDC port for external battery power or use included 12 VAC adapter

So I am sure there are some solutions already out there for external battery packs, anyone recommend any? It would be nice to have a Sony L battery adapter in my particular situation.

Of course we got the 12v lead (car) battery option, with 120v converter to the included AC adapter but that is a bit cumbersome.

So what options are out there and what specific connection actually works with this camera?

Still looking for specs on what the adapter will be..

I have a few of these to power LCD monitors and lights... crossing my fingers it will work with this BMC!

MadDP,
the best way is to go with V-lock or Anton Bauer batteries, and power your camera, your monitor with it.
They aren't cheap... but it is future proof.
And you can rig them on rails.

Not sure I understand how that ikan device would work; Sony L batteries are 7.2 volt, and the BMC specs call for (IIRC) 10 to 18 volts. But if you already have one that's powering 12v batteries, then it would seem a simple task to adapt the power output to match the BMC's input. Gotta be some sort of voltage conversion going on in there...

Also, it's possible someone like Dolgin could make a voltage-converting power adapter, but that's not likely to be cheap. Or, another thing that he could do is make a two-battery sled, so that two Sony L's could power the BMC. In fact he makes a sort-of-similar product already, the vDoubler (http://www.dolgin.net/VDoubler.htm)-- two Sony "L" batteries (or two Panasonic CGR's or two Canon BP's) which power 14.4v Anton Bauer gold-mount products. But it's a pretty big/bulky solution, I can't see how that would be that practical an alternative for the BMC, especially when a battery belt would probably give much longer runtimes and cost a lot less than a vDoubler plus two Sony batteries plus charger.

However, he also makes another product that does look very interesting -- the EX-V adapter (http://www.dolgin.net/EX-Vadapter.htm). That takes a single Sony BP battery (from the EX1/EX3) and mounts it in a sled to provide more common outputs. The Sony BP batteries are already high-enough voltage (14v+ vs. the "L" battery's 7.2v) that it results in a very compact situation, very much like that ikan you pictured, and it's only $50. That's something that could be mounted easily on the BMC somewhere, and at the BMC's power draw, BP-U60 would probably provide about three hours of runtime.

I will be powering with an IDX plate similar to this 5DmkII rig:

52

Is anyone else having problems uploading pics?

Here is a link to the image I am trying to show here:
http://www.westsideav.com/5Dback2.jpg

IDX plates can output 12-16.8v on one Dtap or direct cable I often have multiple coming directly out of the plate. And a second D-tap with 5v or 7.4v switchable, I use this for powering things like the AF100.

And another great thing is you can stack the IDX batteries (if you buy the stackable series) to get long continual shooting or just for achieving good balance with a rig.

I also use them to power lights both on camera and on light stands, a lot of lights like LitePanels or Ikan now can be bought or fitted with IDX plates. It is great to only have to carry one kind of battery. You can even charge your iPhone from the 5v output on the plate.

The multi voltage plate is not the standard IDX plate, if you need multi voltages make sure you order the right plate.

IDX Model P-V257

I just ran across this company, Globalmediapro (http://www.globalmediapro.com/) (who also sell the far more expensive IDX and Sony batteries) and they seem to have some robust solutions at the most decent prices I've seen around.

A V-mount 95W battery (http://www.globalmediapro.com/dp/A2ENC5/Globalmediapro-Li95S-Lithium-ion-Battery-95WH-Globalmediapro-SC1-1-channel-Mini-Charger-TRY-OUT-KIT/) (if the BMCC is 18W, that's ~5h+ lifetime) plus a charger (5h to recharge completely) at $190, and a caddy/distributor/adapter (http://www.globalmediapro.com/dp/A2END3/Dynacore-D-C-V-Mount-Power-Adaptor-for-DSLR-HD-Cameras/) that can be put on rails that outputs 15v, 12v, 7.2v, 5v for $168. I've never bought anything from them. There's a thread on DVinfo (http://www.dvinfo.net/forum/jvc-gy-hd-series-camera-systems/62956-globalmediapro-battery-review.html) on it.

I smiled when I saw the attached photo of Tom Guilmette's RED rig with a Bebob external battery system that powers the camera "for at least 2 mins." between main battery swaps!

Kinda puts into perspective the huge convenience of the BMCC's built-in >1-hour uninterruptible battery power system when used with an external battery. :-)

Am I alone in thinking that Anton Bauer or IDX (or even some other company) isn't going to let an opportunity like this slip by? Surely one of them will make a solid power solution. It took Anton Bauer almost no time to recognize the need for something like the Elipz series. Now it wasn't (and isn't) perfect but they made a lot of shooters happy.

IDX and AB sell their plates, they both have a number of options that are easy to adapt to a shoulder brace or any bracket. These are off the shelf parts available direct from the companies or through resellers, and as parts of kits like I and other kit makers use for our solutions. You can also build your own if you are handy and have some metal working tools and skills and of course time.

The great thing about the BMCC is that you can use the power directly w/o the need to buy the more expensive multi voltage versions and battery paddles.

I applaud BM for doing this, very smart.

I probably will use either the V-mount or AA Rechargeable Batteries Mount from my Steadicam Pilot since I have already got them. In fact a cheap 3rd party supplier might have something similar to the latter, and might be the least expensive (though not the most convenient) solution for a lot of folks.
Something like this provides 4h @ 12V with 10 batteries:

http://www.bhphotovideo.com/c/product/655350-REG/Steadicam_804_7300_Replacement_Battery_Mount_for.h tml

I like this because if I am ever in a place where power becomes an issue, it is good to have a cheap alternative. AA batteries can be found pretty much everywhere, if there is an issue recharging.

should be. the only two 12v dc plug standards are 2.1 and 2.5mm. sometimes they work together. either way you can get adapters no problem. 10 bucks for this plus an average of 2.2 bucks per eneloop AA = 32 bucks for a high quality battery that should be hours of power for BMC

what i'd like to know is if it's safe/practical to use a 12v charger with this setup instead of taking the AA's out to charge them

Cue dumbass question. The camera can recharge itself off these battery options right? I want to be handheld and wont be sticking a battery to the camera but maybe as an absolute last resort I could plug the camera into the battery in my bag for 30 minutes to get 5 minutes out of the camera, otherwise I would just charge up through the mains.

If I use a battery as a quick charge option would some batterys charge quicker than others, what factors would make one quicker than another? I apoligise in advance for my ignorance.

I'm liking this option. http://www.bhphotovideo.com/c/product/503090-REG/Tekkeon_MP3450_MP3450_myPower_ALL_Universal.html

I believe John Brawley mentioned earlier that the BMCC external power connector appeared to be the same as the one on the Hyperdeck Shuttle.

I just bought a HdS (version 1) from B&H for $175 (http://www.bhphotovideo.com/c/product/766053-REG/Blackmagic_Design_HYPERD_PT_HyperDeck_Shuttle_Vide o_Recorder.html), so I've attached 2 photos of its power adapter plug.

The measurements shown in the photos are approx. Also, I suppose there's always a possibility BmD may ship the BMCC with a different power connector, but here it is. Cheers.

I believe there are mobile options such as a battery belt to have it hooked up the camera if you're saying running around with a shoulder rig or handheld. That way the weight is moved to your body, not your quickly-tiring arms.

I bought the BM Shuttle 2 and have just received at 12v pack that takes AA batteries. The unit outputs 14.42v with 12 rechargeable batteries. The centre pin on the shuttle is 2.5mm. The plugs can be straight or can have a slight recess at the very front. The shuttle has flange fingers at the front of the input which hold the socket in place, but you do not need that style of socket as the straight one works very well also. So if the BMCC uses the same input then the pin will be a 2.5mm.

Those two fingers at the front of the centre pin can create some confusion. When the electronics store saw the pin on the 240v power adapter he gave me a 2.1mm inside dia. plug. But those two little fingers spread to allow for the 2.5mm centre pin. A 2.1mm will not fit over the centre pin. Hope that make sense. The pack allows me to run the Shuttle 2 for 3 to 4 hours in the field approx. instead of 1 hour.

Looks pretty promising, this guy got just shy of four hours, powering his 7d, monitor, and h4n, with the cheaper $250 4600mah version.

I'm wondering if I got the 9200mah version with a black magic camera and powering that only, of I might get 8 hours of juice. $400 is more than I'd want to spend, but if it mounts nicely and get a whole production day out of it, might be a good option.

Thank you for mentioning the EX-V adapter Barry. We incidentally have a new configuration of it available (http://dolgin.net/zen_dolgin/index.php?main_page=product_info&cPath=4&products_id=122), created with the BMC in mind - a "mousetrap" lock to keep the battery in no matter how hard you shake it, with a Westside AV bracket for mounting to the camera.

Now add in monitor and/or EVF, audio unit for phantom power and/or mixing, and the drain of lens stabilization, the drain of any signals you send out like Thunderbolt monitoring, plus what else you hang off your rig. Becomes weighty and many more Watts/hour than 18 base of camera.

485I have a rig and half of Lanparte equipment .. it is for the most part well made.
The battery clamp .. I have noted two issues.

1 . If you leave the battery connected with everything off, it still draws current .. fix will be ..
don;t leave battery connected and/or install a switch in it.

2 . You will not be able to hang the batteyy vertically .. it looks as of it's designed to do that .. however there is an error.
The rail block's curvature and the position of the holes that should allow it to rotate to the vertical
are such that it fouls and will only rotate about 45degrees
The solution .. best I have come up with is to grind the rail block down, this is my intention.

Until someone gets this figured out I think I'm just going to external power it the same way I do my Shuttle 2 . . . a Tekkeon 3450.
I haven't had any problems with that so far and it permits me to bolt it to the rails when on my tripod or disconnect it when handheld.
Best part (for me) is that I already have and am using it--therefore not experimental money out of pocket. I like that!

I have never used this product in particular but I would be very leery of any battery pack attached around my waist and powering the camera.
If you are already use to it great. Otherwise I would highly recommend some serious time testing this out with your work flow before taking it out on a shoot with a client.

I'm not necessarily recommending using a battery belt with the BMCC, but just to note: Camera operators have been using battery belts to power cameras successfully for decades, including in the most adverse conditions & situations imaginable.

These days, on-camera batteries are very popular because batteries have gotten smaller & more powerful. But battery belts still have the advantage of taking weight off the operator's shoulders, and can pack a lot of power into a relatively low-cost system.

The only BMCC-specific issue concerning a battery belt is that the BMCC doesn't include a locking 4-pin female XLR power input connector as found on many "pro" traditional ENG/shoulder-mount camcorders and other gear. I'd recommend securing a female 4-pin XLR adapter cable to the BMCC (bolted to one of the cam's threaded holes, or on your shoulder rig or cage) so the power cable from the battery belt has a secure connection point. The good news is that, unlike most traditional gear, the BMCC's internal battery reportedly continues powering the cam when an external source is disconnected or fails.

That is good to know, my concern was operator steps away for a second on a lockdown shot and bam there goes the power. Seems like it's non issue with the BMCC.

Is anyone planning on mounting an external battery directly to a cage? Where exactly do plan to mount it? And how?

2 globalmediapro v-lock batteries just turned up for me (160wh) They will be mounted on a Tilta v-lock mount and powering the camera via the d-tap. The tilta is one of the many v-lock plated designed for DSLRs and has some other connections and leads at specific voltages which can power other bits with more specific power needs.
I'll be interested to see how long I can power the camera and an evf with this, and maybe a little LED light. I'm hoping I can get a day out of a battery so I can have one on the BMC and one on the 7d without having to buy more.

Just saw Ilya Friedman of Hot Rod Cameras saying this:


We also became a stocking Blackmagic dealer, and are working closely with them to design a custom power system for the Blackmagic camera. We anticipate having a shipping version of our battery solution within about 30-days of the camera hitting the streets.

Their stuff is usually top notch, so I guess they have something cool up in their sleeves.

Nice info Frank. I really didn't expect so many third party manufactures getting involved this early on.

Until someone gets this figured out I think I'm just going to external power it the same way I do my Shuttle 2 . . . a Tekkeon 3450.
I haven't had any problems with that so far and it permits me to bolt it to the rails when on my tripod or disconnect it when handheld.
Best part (for me) is that I already have and am using it--therefore not experimental money out of pocket. I like that!Looks like a good option. Itsnot that expensive too. I could buy 2

If I was looking to power the camera all day with 1 battery at an affordable price, would any of these work:

http://www.bhphotovideo.com/c/product/111599-REG/Bescor_LA148ATM_LA_148ATM_Lead_Acid_Battery_Belt.h tml

Also, these battery belts seem to have XLR connections. What would I need to get to go from the 4 pin XLR to the camera?

Thanks!

I'd highly recommend using li-ion batteries instead, there is a reason nearly every modern electronic device currently available uses them. You can get one that will power your camera all day for $150 that weighs 2lbs and has the right DC barrel plug, whereas those ones you linked costs almost twice as much for a battery less than half the capacity and twice the weight and requires an additional adapter cable to power the camera. Plus NiMH suffers from self-discharge, among other issues. Lead Acid is even worse in every respect, especially weight. They are ok for cars though...

I read somewhere that this camera consumes about 18W.. does anyone know if is that correct?

I just received a reply from Blackmagic support:

"There is a 12V-30V DC port available for an external battery power, or you can use the included 12V power supply. The power consumption of the AC power supply is measured at 2.5 Amps."

I guess they measured with 12V, so it is 30W consumption, if I count correctly.

I've got a different number.

I had it on a meter just yesterday. It was 20w / 1.5Amp in record @ 12v.

In the short term I'll be running existing V-Locks and a rail mounting plate I've used it the past till I explore further options as they are released. One item I am looking for however is a P/D-Tap to BMC cable. Anyone have links to such a cable?

anyone know why a 15v v mount adapter would be better than 12v one?
it seems that the 15v ones are more expensive

I have one at my house currently, a little different. I'm going to run it dry see how long it lasts when my BMC hits. If I get even average results I think i will order 1-2 more. Cost me nothing.

For how long should this power a BlackMagic? Also, I though you needed at least 14.4V?
Total rookie when it comes to powering cameras by the way.

Hi,

Does anyone know where I could get a version of this a bit cheaper in the UK

ikan Blackmagic DV Battery Top Mount Solution for Sony L Series Batteries
http://www.adorama.com/IABMCPWRPWS.html

Checked ebay, there's some in Germany but they want 90

Is their a cheaper (but reliable) alternative for L series batteries on the BMCC?

I tested out using batteries like that in the field and they are OK in an emergency. The problem with them batteries is they drop below 12v when they drain past 60/70% and will only charge when the camera is off.

And a drop in voltage means dropped frames...with no warning.

Seriously, I don't understand why people want to risk their footage to save a hundred bucks? I can't imagine getting the perfect take for a client or even my own personal projects and finding out I had a bunch of dropped frames because my cheap battery solution dipped in voltage....

To each there own I guess.

seanmclennan

voltage dips. The camera needs 12V minimum. If your recording and your 12Vs dips, even a little, you'll get dropped frames. Better to run 15V (14.8) and not have to worry about any dips in power causing recording issues. That's my understanding at least.

15v adapters are more expensive because they are generally used for pro gear. That's the only reason.

carlmart

Point taken and agreed on. The question is where to get affordable 14.8v (or so), as the Pocket accepts 12-20v.

I don't know if I'm googling it the wrong way, but couldn't find any such battery until now, except Rolux and else.

The next thing would be to do a series with two 7.4v batteries, which is what IndiPRO and others do on their Pocket external supplies. But you can only recharge them separately.

I am researching this field because I want to see if it's viable to DIY an external battery, paying less than on a Rolux.
