We included the PAGlink Stacking Batteries in our previous New Products to Explore at NAB 2014 blog, and I recently got a chance to visit the Manios booth to see them up close.
As a reminder, these batteries feature an Anton Bauer-style 3-stud gold mount and can be stacked (up to eight) to allow for longer run times. The batteries can also be linked for charging purposes. Watch the video above as I get more details about this unique system from Steve Manios himself.
