Polarity of power cord, BMPCC?

PostSun Oct 13, 2013 2:52 am

I'd like to make a custom 12v battery pack but don't know the polarity of the .7mm charge cord, does anyone know if the center is positive or negative?
Has anyone made a custom external battery yet?

Center is always positive. To confirm just look @ your Switching Power Supply.
And I bought this battery which last 6/8 hours.
One example but you can find smaller batteries

But that Amazon sold battery you showed is for car jumper.

Does it work with the camera?
