Hi everyone!
So I need to power led panel that has v-mount battery plate on the back in some remote locations. Currently I do not have money for v-lock battery so I am thinking of some alternatives. Using motorcycle battery with some transformer, running it from car's cigarette lighter socket, etc.? Any ideas?
Thanks!
 
Any 12v battery (security batteries are a nice size and cheap) would work. You don't need a transformer. Most LED panels should be able to operate directly on the 12 volts.

Another option is to use this adapter along with a couple of Sony batteries. It may not provide you with the longevity you are looking for. But it is a clean, modular solution.

I was thinking about second solution, but then I found this review: https://www.youtube.com/watch?v=slAJIy5GlEg&list=UU5OzkRXqWDsoh0upHgoAunw

So how would you connect that alarm battery with XLR? Any ready made solutions or I will have to DIY a little bit?
 
If you're going to be doing any long term shooting then it only makes sense to get a v-mount/a-b mount solution.
That way when it comes time to upgrade your gear or move on down the track, you'll have more compatible options for powering cameras, other types of lights etc.

Only downside is a more expensive up-front investment, and these days it's getting increasingly difficult to ship the higher capacities.

And I will absolutely do it: buy a proper solution in the end, but for now I need something extremely cheap, something that will allow me to get the shot.
Those alarm batteries looks like a great temporary solution.

Buy a 4 pin XLR cable. Cut off one end and solder on two spade lugs. If you need two cables, buy a cable twice as long as you need and cut it in the middle.
 
If you can use something heavy like a motorcycle battery then you should consider a portable car charging battery .
I keep one of these in my car at all times (if I leave the lights on) and have often used it as a battery for portable lights or monitor.

Great unit and much easier to haul around than a motorcycle batt. Just get yourself a cigarette lighter adapter for whatever you want to power. I carry a bunch of converters to 4 pin XLR, 2.1 and 2.5mm DC etc.
 
+1 For the jump start unit Lenilenapi suggested. I have been using them for years to power many things on set. Though I would never say they are a proper substitute for v-locks which I use . A moderate size unit with proper cables will get you by for now. Then you can use it to power the client monitor or as I did my remote head on the jib etc. I still have a couple of old battery belts that come in handy and are still holding a charge.
 
Thanks guys, this is exactly what I was searching for :) That jump starter looks solid and even bringing it on pro set doesn't look too DIY.
