Guest Vadim Trofymenko Posted December 22, 2012 Share Posted December 22, 2012 Hi, please help me build battery for 16mm Kinor 16 CX 2M. Battery should be 12v 5-7A. At the moment I'm using a motorbike sealed battery, but it's heavy and it takes long to charge it. I saw some people convert DeWalt 12v batteries to use them with Arriflex cameras, which is basically the same as Kinor. I need it to be with 4 pin XLR connection and at the same time to have original connector to charge it using original charger. If anybody can post some king of plans, schemes or pictures how to do it I'd be very greatfull. Thanks. Link to comment Share on other sites More sharing options...
Guest Vadim Trofymenko Posted December 22, 2012 Share Posted December 22, 2012 Here are some pictures, I want to fixe it to the camera like on first picture. So I can move the camera freely without lods of cables running to the battery. longvalleyequip.com/adapter.php Link to comment Share on other sites More sharing options...
Premium Member Phil Rhodes Posted December 23, 2012 Premium Member Share Posted December 23, 2012 If I wanted to do that, I'd just buy some nickel cadmium or nickel metal hydride cells and put them in a box with an XLR on it. I've done this a few times and it's a fairly low cost way to obtain batteries. I actually have some parts here now that I bought to do this with - these NiMH cells (that's a very good price, as they are high quality cells), some normal battery holders, and miniature volt meters. I'll simply use a plastic project box (I haven't bought those yet), and 12 cells per pack to create a 14.4V, 2000mAh battery. I don't know if this would be adequate for your camera since NiMH is not as good at high current loads as NiCd, but you could do the same with bigger cells, and use NiCd rather than NiMH. Avoid lithium ion cells. They could work, but they require a lot of complex electronics to work really well and have a short life, even if you don't use them. Also, you aren't allowed to take them on aircraft unless they have passed expensive safety tests. For charging, I have had good luck with chargers like this. They can handle NiMH, NiCd, lithium, and even lead-acid batteries, and have a lot of programmable features. What's more, they run from 12V, so you can charge in your car. Of course, this is very much a homebuilt approach, and probably won't have the reliability of off the shelf batteries, but it's probably the cheapest way to go if you don't mind a bit of construction work.

I need it to be with 4 pin XLR connection and at the same time to have original connector to charge it using original charger. If you don't have any familiarity with really basic electrical stuff then the cheapest option is probably the 12V gell cell (bike battery). You can put it in a bum bag (money belt). Maybe a smaller one if you don't really need 5-7Ah ? If you are just exploring on your own then naving two batteries is probably ok. Having only one can be a real pain. Making up packs is quite easy if you have some basic experience with electrinocs, soldering etc. Normally the cells were soldered together. You can get cells with little metal tabs so the soldering is easier, safer. Find out what Ah people commonly have for an on board battery pack, then you can see what cells suit and how to wire them.

Gregg MacPherson Posted December 25, 2012 Share Posted December 25, 2012 (edited) I just read your other post and realize I probably misread you. Your peak current draw is 5-7A, yes? What I was suggesting basically stays the same. What is a common battery capacity for those cameras? (Ah or mAh) I did quite a lot of operating with a separate battery. I actualy liked it better. It made the camera lighter. But if you don't like that then the gell cells are maybe too heavy, so you have to make up some NiCads or NiMhi packs.

Guest Vadim Trofymenko Posted December 25, 2012 Share Posted December 25, 2012 Hi Gregg, thanks for reply. Yes it needs to be 12V 7A. Good advice, but again, maybe you know something like DV Link System or any other light alternative that charges fast and is under £200? Link to comment Share on other sites More sharing options...
Jaron Berman Posted December 28, 2012 Share Posted December 28, 2012 (edited) Off the shelf: http://www.milwaukee...er-port/2349-20 use 12v milwaukee batteries and any of this type of cable: http://www.bhphotovi..._Cigarette.html Done. I believe the "3A regulated" is on the usb port, the 12v port should be totally unregulated. If not, its pretty easy to just open it up and remove the regulator so it's accessing the battery directly - and using something like this means minimal gaff tape - nice and clean.

Again, I don't get how to connect them. For example, THIS is the battery I want to use. I'll need some sort of adapter like for DeWalt anyway.

Guest Vadim Trofymenko Posted December 28, 2012 Share Posted December 28, 2012 Got it! I think I should give it a try. Looks like the best option at the moment. Link to comment Share on other sites More sharing options...
Guest Vadim Trofymenko Posted January 11, 2013 Share Posted January 11, 2013 UPDATE. Bought a Milwaukee 12v 3A battery + Cordless Power Port + 4pin XLR + some cables = £80! + £20 for a electrician to solder four wires together here in London! Shame! £100 total cost. The question is, could I have found a 12v 3A battery that charges in 30 minutes from arri or aston camera and recell it all together for $160? Will post some pictures of my set-up on Monday.

Premium Member Phil Rhodes Posted January 11, 2013 Premium Member Share Posted January 11, 2013 You could have bought a soldering iron for that! Link to comment Share on other sites More sharing options...

Premium Member Will Montgomery Posted January 16, 2013 Premium Member Share Posted January 16, 2013 Jaron thanks for this... I was going to ask the engineers to make some of these up and here they are at B&H for $17. I have a couple of battery powered compressors with cigarette lighter outs that I thought would be perfect as backup batteries at least. Link to comment Share on other sites More sharing options...

Guest Vadim Trofymenko Posted January 16, 2013 Share Posted January 16, 2013 Not the best looking one, but pretty good solution. Charges in 20 mins. Link to comment Share on other sites More sharing options...
Premium Member Phil Rhodes Posted January 16, 2013 Premium Member Share Posted January 16, 2013 Not pretty, no. But probably effective! I'd wrap some tape over those exposed terminals. There's no risk of electric shock at 12V, but it could start a fire if shorted out. P Link to comment Share on other sites More sharing options...

Simon Ng Posted August 11, 2013 Share Posted August 11, 2013 Still people using 16mm camera ? Link to comment Share on other sites More sharing options...
Brian Drysdale Posted August 16, 2013 Share Posted August 16, 2013 Super 16 is still used for various types of productions and people use it on their own films, however, nothing like the levels in the past.. Link to comment Share on other sites More sharing options...
Simon Ng Posted November 20, 2013 Share Posted November 20, 2013 I thought now days 16mm already replace by Canon5Diii or 60D with Magic Lantern Raw file & HDR, Big sensor + shallow dof. or BlackMagic Cinema 4K :) Buy Resolve, free Camera :) Link to comment Share on other sites More sharing options...
Philip Nasadowski Posted November 22, 2013 Share Posted November 22, 2013 I don't have the coin for a BMCC (I'm a hobbyist), and anyway, I like film. For my Bolex, which has the external motor, I used a pair of lead acid security cells, and a cord long enough to allow me to put the pack on the floor and move a bit. I got a little camera bag that they fit PERFECT into, along with the moto and a roll or two of film. Heavy? Yes. But, the long cord makes it less of a headache, and it's PLENTY of capacity - it's not going to die suddenly on you. Link to comment Share on other sites More sharing options...
