Hello everyone. I'm getting ready for a shoot this coming winter and looking into backup power sources for my camera. For my main power souce I'm using three Switronix V mount batteries. I don't know yet if I will be shooting on BMCC (12v) or Red One camera (14.4v). The question is, what should I know about connecting my cameras to acid batteries? Will I be fine with just connecting the right battery (battery with correct voltage) straight to the camera without any converters? Also, how do those acid batteries perform in cold/sub zero temperatures?
Would appreciate your help. Thank you.
