@JackBayer, thank you, that is the fastest (chipest) solution. Just wonder about the quality of the cells, do they hold ?
@feha: I have the battery holder from ebay.. but now I'm already using one which is meant for liliput monitor... it has a locking pin, so battery is safely held and have some mounting options too.
I got the step up - down converter module. Amazing DC2.8V-32V input very stable output. Waiting for some more parts than will put a video tutorial.
Tested, this step up down converter works OK but it gets hot ... even on low consumption ...
Yes, I have the same battery holder now ;) ... I managed to put the DC-DC converter to DC coupler... so now I just directly connect the Sony battery.
@feha Did you try that ebay 12,9,5 battery? What sort of voltage ranges did it up putting out?
@sam_stickland I ordered the same ages ago, but I'm still waiting for it :-/
No did not test the battery 12,9,5 ... On the picture i use NP970 and works great ... this solution allows to use any battery range 3v to 32v this gives more flexybility to use any link of batteries ... @Alfi666 That's ok, but just be careful about heating, won't be good to get heat inside GH2 body ...
@feha Thanks. I'm thinking to power my GH2, Tascam DR100 and eventually a small monitor off a single battery solution, so I was hoping to find one that already has a choice of stable outputs. It seems a little clunky to have three DC-DC converters off the back of a single battery.
@sam_stickland I'm waiting for ABS plastic project box, a small one, will make a tutorial. Adding two of these DC-DC you can get one input any voltage:3-30v and stable output 9v and 12v if you add one more Dc-DC can get even 5v ... so three DC converters inside one box with one input and three outputs ...
@feha my next port of call is to buy the lanparte battery pinch, and add my own 9v dc plate mount connector through one of those multivolt converters.
5400mah with 5V and 10-12V outs for less than $20. Think it'd power H4n and GH2 out of the box, or would you need to step down from 10V?

still, i think this is the best option: http://www.ebay.de/itm/170556707790?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649 5v: 15.000 mAH 9v: 8.500 mAH 12v: 6.500 mAH
for 23,73 USD :)
you will need step down as i think 10v is too much for GH2, but if you can get 9v battery that should work fine without converter. I have bought this one: http://www.ebay.ie/itm/200711976856 and will be using step down adapter. As i can't trust these batteries, decided to get a stable output, more security. Also 12v can be used with most other equipment.
@fatpig check sellers feedback, many complains on similar selling products (some never get it, some could use it just once ...) ...
be careful, never use any higher voltage on that converter. (http://www.ebay.ie/itm/320801253113) If you by accident connect 12v it will out-put +difference (14-16v), this may brick your GH2, there is no voltage stabilization !!!
@feha: there is one user on this forum who uses this battery for his setup, i think it was in this thread.
We are shipping a stand alone converter now http://dolgin.net/zen_dolgin/index.php?main_page=product_info&cPath=18&products_id=113 it allows to use any battery 10V-25V as it puts out 8.9V for the GH2 camera. The smart algorithm based LED voltage monitor is built in.
@fatpig sure, he was happy one to get it, I'm afraid of fake facts when they declare mA/h
@alexdolgin that's great but for us in EU price + shipping + customs etc ...
Hmm... contact us directly so we could find a cost effective shipping option to EU .
@alexdolgin Just check out your GH2, SL DC converter. The dimension listed is 3"X2"X6". The size is as large as a V-mount battery. Can't this be made a little smaller?
PixCanFly, it is .6", not 6". Can you point where did you see the wrong dimensions? I can not seem to be able to find it. Thx
@alexdolgin my apologies. I missed the decimal point. BTW, do you have this listed in B&H?
