Hi all
I want to make a very light camera right that supports a shogun via d-tap. I'm basically looking for a very light weight battery pack with d-tap, I really don't want a standard chunky anton bauer/vmount battery.

Anyone got any suggestions of an alternative or a very light weight lower capacity battery of the types mentioned ?

The SWIT S-8U93 is exactly what you're looking for. If you have an A7S/A7R/a6300, it has a USB charge port that can supply the camera with power at the same time as supplying D-tap. And if you use a battery plate for the Shogun, you can add another thing to the spare D-tap on the battery.

S-8U93 86Wh Battery For Sony BP-U Series (http://swit.us/s8u93-sony-bpu-series-dv-camcorder-batt893.html)

It charges in a Sony BC-U1 charger.

Zacuto has a small battery that rides on 15 in. rods.
