Guys, so I am looking to power the brain from a custom made battery. Can you help me ID the pins that need to get DC voltage and what range it can tolerate?

thanks!
 
Also what cable do I need to cut open to get leads....? anything on the market with the epic connector and wire?
 
Ha! Certainly not saying I have done this for powering certain RED brains via helicopter gimbals and cable cams and the like... But this picture turned up on my desktop somehow.

The pinouts are in the back of the OPS guide. You just have to make very sure than both the positives are positive and both the negs are neg. (or so I've heard)

It may or may not be a very cheap, light, and efficient way of powering RED brains :)

Nothing wrong with RC lipos if you're well informed and sensible. I'd suggest using a LVC / voltage warning to prevent the camera dropping the cells below their critical voltage though, as you really want a 4S battery, and the camera could run the pack to below 12v (ie sub 3.0v / cell).

Ops guide has the pinouts, Lemo will sell you the connector. The R1 style connector is cheaper and more available in my experience, which is fine if you have a 2b-1b around. Also a little easier to assemble.
 
We run the epic on some strange power sources when using the milo and I know that if it goes down undr 12V the camera will complain and shut down and if it goes above 18v or such I think it will complain aswell. So running the camera from 14.8V RC cells will work just fine.

The most easiest is to cut the cable to your charger and put on a XLR female on the AC end and a male on the other end. The you got a short cable that you can use with your AC and if you make a RC bat conector cable with a XLR female in the other end you can jump inbetween.

The RC batteries are long lasting, low priced, and very reliable and low weight so I think it's a good choice.

Here is a link on how to cut the wires: http://www.reduser.net/forum/showthread.php?75537-How-the-AC-power-should-be&highlight=
 
Just make sure you have a handle on how those things like to work. They are much more delicate and fire prone than batteries for cameras.

Did you get this wired up?
I'm looking for the same thing and wanted to know if anyone out there could make me a cable?
