The Tekkeon battery packs i'm using can vary voltage from 5V-19V DC. You've probably seen me powering up the 600 /900 LED light panels and also the ASUS Wireless HD streaming WiCast. By using a simple coupler, I can attach it to the Canon OEM AC-E6 wall adapter dummy battery and power up the Canon DSLRs. For those who want to use this on a rig, check out the video review I did on the Tekkeon Snap Package which adds on a second battery for extra capacity, and 15mm Rig mount from CPMFilmTools (here). Bits and pieces needed for this mod found below.

This little battery mod is not exclusive to just Canon DSLRs. I know that even Panasonic GH2 cameras have a wall adapter (found here) that outputs 8.4V DC. The Tekkeon battery just happens to have that exact 8.4V setting too, making it perfect to use something like this for longer run times on the GH2. You just need the adapter that comes with the dummy battery.
