    Here it is on Ebay for a bit more but it's larger too. http://www.ebay.com/itm/9V-12V-15V-16V-18V-19V-21V-18000mAh-Li-ion-Super-Rechargeable-Battery-Pack-whit-/200826090708?pt=PDA_Accessories&hash=item2ec22af4d4

  • vicharrisvicharris

    Hmm, it's been removed from Amazon. I can't find it anymore but its a large battery for laptops and phones. I believe someone has a link in this thread before. It's completely gone now!

    @vicharris Sounds pretty damn good. What is the ATC?

  • vicharrisvicharris

    Just an update if anyone even cares :) just spent the second half of a shoot day using the ATC. Probably shooting 5.5-6 hours and the battery indicator is down to 50%. Not too damn bad!

  • vicharrisvicharris

    The ATC just plain rocks.

  • rajamalikrajamalik

    will this work for gh2???? the only diffirence is its amp. coupler shows it should be 8.4v 2a but this battery here powers 8.4v 4a, will it work well??? any possible problems found in increased amp?? http://www.ebay.in/itm/Lithium-Ion-Rechargeable-Battery-Pack-8-4V-2000mAh-2C-/300811873502?pt=IN_Mobile_Accessories&hash=item4609c8ecde#ht_844wt_1156

    For Canadian users we can't order the ATC battery because they won't ship to Canada, so what I did was bought this: http://www.amazon.ca/Anker-10000mAh-External-E-readers-Nintendo/dp/B005NGKR54

    The capacity isn't as big as the ATC but it will be more than sufficient to provide several hours worth of recording time. I use this with an aftermarket DC Coupler and works fine.

    Just another option out there for those looking for an external battery solution in Canada.

    I received the CCTV camera battery (5v/9v/12v). And the only problem I've found out the 12v - 12v cable from the box was broken. But I didn't plan to use the cable anyway because it's too short. I've made few own cables suitable for anything - Feelworld monitor, 160 Led lamp, GH2 DC coupler, few synths of mine (Yamaha An1x and DX200) and even molex output. I've tested the power with a couple of 12cm system fans which I though will be working 3-4 hours. But the fans has been working for 9 hours!

  • vicharrisvicharris

    Damn you UPS, damn you!!!! Where is my power supply?

  • TGDudeTGDude

    @artiswar - it's awesome. Nothing else needs to be said.

  • thepalaliasthepalalias

    @vicharris I bet you'll like it. :)

  • vicharrisvicharris

    Still waiting on mine! Have a cheeseplate and rail blocks waiting for it. :)

  • thepalaliasthepalalias

    @artiswar Here is the link I used: http://www.amazon.com/External-15000mAh-Motorola-Portable-eletronics/dp/B0067XMQD8/ref=sr_1_1?m=A2220UWPX1VUDX&s=wireless&ie=UTF8&qid=1350348847&sr=1-1&keywords=atc+15000

    There are two models available on Amazon.com. The most important thing would be to buy from the manufacturer on Amazon, not from another seller. My experience is with the 15,000 MAH model, not the 18,000 MAH one but from the pictures and descriptions, they seem similar. I also don't think it matters whether you buy from ATC from their eBay site or their Amazon store.

    If you buy the 15,000 MAH ATC one and for some reason need a larger capacity (or the solar recharging option) then you can take a look at their other options. You want to make sure it supports 9v and has the correct adapter. If you write them to check, reference the picture below.

    http://ecx.images-amazon.com/images/I/41T9vviFe3L.SS350.jpg

    In that picture, look at connect closest to the bottom right corner of the power pack, and go three more steps to the left - it's the black one between two yellow ones. That is the one that connects to the GH2 coupler. If for some reason it's not included by default with other power packs the company offers, you may be able to write the company and ask them to (since it is not an expensive part).

    As for the unit, it's still working well. The only thing I have not tested on it is how long it holds charge if it is not used (since I consistently use it fairly soon after I charge it). Still no problems.

    The one thing that can be a little tricky at times is judging how long you have left when there are two bars left on the indicator. It discharges from 4 to 3 much quicker than from 3 to 2 and then it stays at 2 for a really long time. I am not endorsing using it for flashing firmware (read the directions in the FAQ on that) because it easier to disconnect the cable accidentally than to accidentally eject an official battery. However, if someone does it use it to flash firmware, I would consider it essential to make sure that there are at least 3 indicator bars on the battery.

    @vicharris @oscillian @Mike_C @TGDude @thepalalias - Considering picking the 15000 mAh power solution up. How is it holding up? Is the $53 ATC pack on Amazon the same thing?

    Thanks!

  • oscillianoscillian

    @zigizigi Thanks! That's more like it :) And it even comes in black...perfect!

  • zigizigizigizigi

    @oscillian - They are available on ebay directly from manufacturer: http://stores.ebay.com/All-Powers-Inc/15000-23000-mAh-/_i.html?_fsub=524796119&_sid=1115083619&_trksid=p4634.c0.m322

    The model available is a bit pricier but has even more capacity - 18000 and includes worldwide shipping. They also have black ones which are rebranded as Naztech elsewhere.

    I'm going to pick up one of these ATC 15000mAh units, but am a little confused on the DC coupler situation. I've already got one of the aftermarket "HQRP" AC adapters that comes with its own DC coupler; that set up works fine, so far. I'd like to use that coupler if I can, but I can't make sense of whether this particular coupler has a reversed polarity from the official Panasonic one. Is this the case, or am I misconstruing this information? $20 is no big deal, but still... it's $20...

    Thanks to everyone who has done the legwork so far on this power solution--looks to be the ticket!

  • oscillianoscillian

    @thepalalias That $53 ATC 15000 mAh from Amazon doesn't ship to Sweden and the ebay/amazon UK supplier charges $220+shipping! Any ideas on how to get it cheaper to Europe? @Vitaliy_Kiselev Maybe a PV deal for us Europeans?

  • vicharrisvicharris

    Thanks guys for the leg work on this subject. @TGDude Great find and research on that ATC 15000 maH Power Bank. Going to order one today and damn it looks sharp!

  • Mike_CMike_C

    I still haven't had the opportunity to recharge it, but I'm a little worried 'cause it's not the first time I hear the battery won't recharge ... (sigh)

  • bangkngbangkng

    @crfilms when you recharge that battery, you have to turn the battery to the on position. but be careful not to leave it charging too long. one of my charger burned out cause i left it on for 8 hours.

    I wound up buying the original cheap battery option from that guy because it had the full kit with adapter and coupler. Also since it was an american shipper I don't have to wait 2+ weeks to get it. So far so good, testing out how long flowmotion 24L will record.

    Anybody know how long it takes to recharge and if there's anything you can plug into the usb or another port that has a display to see how much it's still charged?

    EDIT: Worked for 7+ hrs the first time, now after charging for 7hrs, it worked for an hour and says, "battery cannot be used". Sigh.

  • thepalaliasthepalalias

    @TGDude So far I very much agree. The recharge was pretty fast, too. Around 4 and half hours to recharge after 13 to 14 hours to deplete to the point where it stops powering the GH2.

    I am going to try to test how long it can "safely" be used for (as in no risk of the GH2 turning off) in the coming days, but I would hope at least 12 hours.
