gabilourson — Fri, 27 Feb 2015 06:14:18 +0000

Hi guys, I bought by personal-deals the Varavon GH4 battery, but it's impossible to charge it :) I tried for long durations... And paper instructions is really mystery... I searched more explanations on varavon web site, on youtube etc, but I got nothing... If someone has more info ....

FLEXIOM DC Converter for DSLR-s and all stuff requiring specific voltage.

feha — Fri, 17 May 2013 18:23:28 +0000

Official name for this product will be: FLEXIOM

Flexible Input Output Manager (or Module) ...

The official website will be http://flexiom.com (under construction).

Support: feha[@]flexiom.com

P-V members will get rebate.

I have decided to make DIY product for Universal DC converter. This unit will allow use of any power source 3-30v as input and max output current will be 2A. The unit consists of voltage converter that gives you adjustable output for example GH2, GH3 8.4 V or any other equipment that is sensitive and requires exact voltage.

Consider this unit as a protection "Layer" between your DSLR and any power unit.

I know there are many ready power solutions already out on the market, but many still struggle and burn/brick their expensive equipment trying different alternative powering sources.

I decided to take my time and make this DIY product as a test but if there is an interest might get as batch production.

The unit will cost a $75 USD + postage (P-V members price). More than 65% of the price to buying needed components the rest a small compensation for research, drill and soldering :-)

For EACH UNIQUE SALE (per member) I will contribute a $10 USD to support P-V !

Product components :

ABS plastic project box
Electronics component (The converter)
DC IN/OUT 5.5x2.5 mm jacks
Digital Voltmeter (RED) with external switch to check IN voltage, OUT voltage and OFF

Let me know your interest ?

V-lock Solution

Hi, I'm looking for a v-lock battery solution, to power GH2 / TVlogic 5.6 external monitor etc.

Does anyone have any recommendations please? I've found these two:

Lanparte http://www.ebay.co.uk/itm/Lanparte-V-Lock-Battery-Pinch-Power-Distributor-HDMI-Splitter-for-DSLR-RIG-/161071666608?pt=UK_Tripods_Heads_Stablisers&hash=item25809e95b0

I'm assuming the monitor would be powered from the Dtap, and camera from the DC out 12v?

Cheers Jon

GH4 aftermarket battery shootout

willu — Sun, 30 Nov 2014 20:37:02 +0000

I had to buy a ton of GH4 Batteries the other day and though I would do a quick comparison between some of the best selling options. I also included a ton of info about recording times and memory cards in this video as well. I'm going to be doing something similar for the Hero 4, so my goal is to know which of these aftermarket brands is reliable in terms of capacity, functionality, etc.

Problem with external battery in manual focus with Sanity 5.1

haribabis — Tue, 22 Jul 2014 11:09:51 +0000

Hello! I bought the external battery in the picture and i have a strange problem. I use @Ralph_B hack Sanity 5.1. Only in manual focus after a few seconds recording, i get the message "this battery can not be used" and GH2 is turning off. Everything is working OK with noname and original batteries inside the GH2, in auto and manual focus. I reload the original firmware and connect the external battery and there is no problem in manual focus. It appears only when i have Sanity hack, manual focus and with the external battery!

External battery options for GH4

mrbill — Thu, 27 Mar 2014 06:20:31 +0000

I'm going to modify my GH2 external battery step up unit (to use with the powerbank batteries I've already bought) for use with my GH4 when it arrives. As the GH4 seems to use the same batteries as the GH3, can anybody confirm the voltage output of the AC adapter for the GH3? Many thanks.

usb charging Lumix G batteries

lenuisible — Fri, 27 Jun 2014 05:48:24 +0000

I recently bought a battery bundle on amazon (patona one) for my GX7, and I had the good surprise to discover an usb enabled charger ! The batteries are not that good (they don't last much), but the usb input on the charger is really a nice option.
I recently became fond of external usb battery (like Anker or similar ones), I can now charge my smartphone, my portable speaker and my GX7 batteries with it.

I'm pretty sure all the Patona chargers for lumix G camera have that option.

Or 8.4V as in original power supply is required?

DIY battery pack for 3.7v Canon Point and Shoots

ragnar — Tue, 18 Feb 2014 15:35:33 +0000

I copied someone else's plan to do this. This is my attempt. It's working for me and my Canon S100, S110 and ELPH 300HS cameras for my bird photography. With two factory batteries it supplies 4.10v, which apparently the cams don't mind as they haven't melted...yet. Anyway, I know little to nothing about electrical things and terms so if I can make it work you can too. I made a video of what I did. There are two parts. Part 1 is about 11 mins long and Part 2 about 5 mins long. I've built and tested two of these, one for the ELPH and the other for the S100 and S110. I realize that there are many other ways to do this but I liked this way because it used cheap chargers (I paid about $3 for each) and the standard batteries. I have one outside right now taking pics of winter birds. I got 4hrs and 10mins from both packs as I tested them each. That's about double the time I used to get with just one battery in the camera the normal way. Also, in hindsight, I didn't need to order Canon S100 and Canon ELPH 300HS specific chargers as the bottom line here is the 3.7v, which both NB-4L and NB-5L provide so I could've just ordered one type and went with that. Oh well, like I said, I don't know this stuff.

Part I:

Part II:

Here are two recent birdy pics using this method.

Solar power charger that works with the GH2 batteries

Mike_C — Tue, 12 Jun 2012 05:00:56 +0000

Battery solution for Panasonic G6!

kombai — Mon, 04 Nov 2013 11:56:51 +0000

I bough Panasonic G6 a week ago. As I am person who makes documentaries from remote areas on our planet (Papua, amazonia...) I sometimes do not have access to electricity for one or two weeks. The battery life in G6 is only 1 hour and for me it means to have about 15 batteries in my bag... So there is a battery solution for Panasonic GH2 that can make about 14 hours juice for a camera:

As the batteries are the same I made it but when turning on my G6 switches off after 3 seconds and displays "this battery is not supported" I know that there is a chip in battery and in camera but is there any way how to cope with it?

Thank you a lot!!!

GH2 battery grip for 110$ (Finally Available!)

stefanos — Mon, 26 Dec 2011 09:13:54 +0000

I had sent an email to "ownuser" many many months back asking about making a gh2 battery grip. I got a reply yesterday that they finally have a gh2 battery grip available.

Below is the email I received where you can see company details and links. I know they have an ebay store so my guess is it will pop up there soon but I haven't seen it there yet. I haven't ordered one yet but I definitely want to get one cause I need 1) a proper + safe powering solution without hanging weird batteries and without buying absurd OEM batteries 2) sth to add more "masculinity" to the miniscule and featherweight gh2

"Dear Customer
We will tell you a good news.
About PANASONIC GH2's grip is already on the market in 2011/12/20.

On this website, you can get more product information.

On this website, you can buy products through PAYPAL (online credit card page, like EBAY)
http://www.ownuser.com.tw/e_paypal_panasonic.html

MIG-PGH2 has four purchase specifications
(1) MIG-PGH2B = only BODY (B = BLACK)
(2) MIG-PGH2AB = BODY + MEB-03-c (A = external AA battery pack)
(3) [New specifications] MIG-PGH2RB =BODY + mini IR 2B & RHS (R = IR Remote, not the wired remote control)
(4) MIG-PGH2RAB = BODY + MEB-03-c + mini IR 2B & RHS

We recommend to buy (1) or (3).
Because AA batteries is not recommended as the main power supply that use on GH2 cameras.

GH2 Charger emergancy - Stockholm

FilmCat — Thu, 11 Jul 2013 05:10:22 +0000

Hi guys,

I've made a bit of a fool of my self, in the panic to get to the airport on time arrived with seconds to spare, I left my spare GH2 battery and charger at home :( I was wondering if I could borrow one for a week from anyone around Stockholm, it would be an absolute lifesaver!

My film would otherwise be ruined as you can imagine...

I'm about to get on the plane so will check the forum in about 5 hours

Thanks everyone, Max.

Anton Bauer 160Ah battery life with GH2 & monitor

LucasAdamson — Fri, 12 Apr 2013 19:35:01 +0000

So, building my GH2 rig, I want a big Anton Bauer style battery on the back to power my monitor/ viewfinder and the GH2.

The added advantage is that it will balance the rig and place the weight all on my shoulder, and off my hands and arms.

So, here's my calculations, which are a little alarming:

GH2 is 3.4W (nominal) power consumption Neway 7" monitor is 8W power consumption

8W + 3.4W = 11.4W

160Ah battery is the Gold mount battery I am considering, from Globalmediapro.com - about £170

A x V = W

160Ah x 14.4v = 2304Wh

2304Wh / 11.4w = 202 Hours!!!

Could it even approach 202 Hours?

To check I looked at the same calculations with a 7000mAh (7Ah) large camcorder battery, which came to 4.4 Hours, which is believable.

So, 202 Hours!!!????!!!! Really? Did I go wrong somewhere here?

LanParte Power Kit - GH2 compatibility?

Sangye — Fri, 25 May 2012 00:28:57 +0000

I'm very interested in Lanparte shoulder pad / power kit for my GH2 rig, but it appears to only have 15v, 12v, 7.2v, and 5v outputs. Is there any reason why taping a voltage regulator on and using the 12v output would not work? Also, does anyone know of a similar system available for less $$?

Non-Sony NP-F Batteries. Any suggestions?

Siddho — Mon, 06 May 2013 16:22:24 +0000

I am looking to buy 4 of the larger Sony NP-F batteries (NP-F960 or 970). The original Sony ones are extremely pricey but there are a lot of aftermarket NP-F batteries out there for reasonable prices.

Has any one had a good experience with a specific brand and can any one recommend one or two names to me?

Thanks in advance for any help.

GH2 DC coupler to battery questions quick help

Athiril — Fri, 19 Apr 2013 23:44:21 +0000

Left battery charger elsewhere, cannot get back for tomorrow's shooting at 11am. Battery flat.

Electronics shop open today but not tomorrow, closes at 5pm today (1:36pm as of writing), I'll get there about 45 min before it closes (currently at work).

Not a huge lot of options. But I'm going to see if I can rig up a simple voltage regulator based on zener diodes and a resistor with 10x AA Eneloop XX's (just under 14.3v total at full charge voltage iirc). They dont have a large variety, the best looks like a 9.1v 1watt zeneor diode, producing a maximum current of 110ma by the looks of it, so I'll stick a bunch in parallel to raise the maximum current output.

The question is, how much max current do I need for powering the GH2? Just need an emergency option without over-volting the camera (what is the highest safe voltage btw? Eneloop XX's provide very stable voltage for what they are).

Otherwise one option is to power regular with regular Eneloops, from testing, high current draw, the voltage sag is minimal, and stable over it's capacity.

In Melbourne CBD, Australia if someone has an alternative thats open till 5pm today

edit: Just read you can't easily put zener diodes in parallel.. well this is annoying

Rig Powering Options

Has anyone a good recomendation for a V-Mount or Anton Bauer battery system to mount on the shoulder pad (via 15mm rods).
I want something to power, camera, monitor

I found this on ebay, but built quality and price looks not very convincing to me:

http://www.ebay.com/itm/130Wh-BP-Battery-V-Mount-HDMI-5D2-D90-7D-DSLR-Rig-/260814203747?pt=US_Camera_Battery_Grips&hash=item3cb9bceb63

Also this Pro Aim solution, but from what I hear, their stuff is not so great either.

http://www.ebay.com/itm/Proaim-JUNCTION-BOX-V-Mount-battery-plate-/200646730983?pt=AU_Cameras_Photographic_Accessories&hash=item2eb77a24e7

Has anyone better sources?
A deal with 2 batteries and charger and the mount plate for the rig would be perfect.
