GH3 DC Coupler and external battery
 

Hi, I saw a video on cheesycam.com which showed how to connect an external battery to a GH3 (http://cheesycam.com/panasonic-gh3-e...ry-dc-coupler/). I am in the UK and I noticed DiGiBaBa do GH3 comparable 'DC Coupler' (http://www.amazon.co.uk/DiGiBaBa-Com...dp/B006ZA8YIY/) and a Ex-ProA do one with a mains adapter (version with a mains adapter (http://www.amazon.co.uk/Replacement-...dp/B006MNDWPE/).

Anyone know if either of these can be used with an external battery and if so what battery?
