GH2 Extended Battery Options

[popalock]

I'm shooting in 3 hour blocks (in 45min intervals) and swapping batteries from my GH2, but having been connected to a tripod is proving a total b!tch.  So I'm looking for options which would be either an extended battery pack OR a much easier way to QUICKLY swap out batteries while being connected to a tripod

Any ideas? 

I've found this [url=http://dolgin.net/zen_dolgin/index.php?main_page=product_info&cPath=18&products_id=99][b][i]extended GH2 battery plate[/i][/b][/url] but it's not particularly cheap + I'll have to think about where to mount it(and so opens the door to more problems)

This battery grip looks pretty cool for a china product:

I made a very simple flat plate that goes under the camera and provides a tripod mounting point offset well away from the battery door.

I also have done the custom made battery setup which works for 6hrs or more.

I use v-mount batteries and a Switronix adapter [url=http://www.switronix.com/news/204-switronix-releases-xp-cable-for-panasonic-lumix-gh2]http://www.switronix.com/news/204-switronix-releases-xp-cable-for-panasonic-lumix-gh2[/url]

I added sensor connectors (similar to LEMO, not as good but cheaper) and it works really well.
