Finally received my DJI External Battery Extender & Battery (2PIN) to DC. I'm excited to have "extended power" especially for longer time-lapse and lengthy Corporate events that we cover. As an Inspire owner I'm also excited to "dual use" our investment in batteries (11-TB48s and 1 -TB47). Only thing I've found lacking was the "Battery (2PIN) to DC" connection to the Inspire battery. It's way too easy to disconnect and Inspire batteries by themselves aren't particularly easy to carry and hold on to. We developed a belt-clip that utilizes the Inspire "squeeze to release" connection and engineered the "Battery (2PIN) to DC" connector internally to insure it doesn't mistakenly get disconnected while shooting. Going to be putting it to use the next couple days as we record a lengthy time-lapse "Sign Installation" video on a 500+ foot building downtown Denver.
