Post Re: 30,000 mAh Li-ion Battery
I've used similar batteries which worked very well. They have a lot of power, weigh a lot less than lead batteries and they seem to last longer before you have to buy a new one. The capacity of these packs keeps growing, this is the first I've seen which is this large. I'll probably get one of these next time I attempt to use solar panels.

What do you want to use the battery for? Do you want 12 volts or do you want to run a camera at 7 volts? That 12 volt battery will take all day and all night to charge completely. If you want to power the camera and nothing else, check out these 7.4 volt batteries for model cars. They need a special charger and don't seem to be available with more than 5,000mah, but that powers my camera all night and they recharge in just a few minutes.

http://www.ebay.com/itm/7-4v-5000MAH-30 ... 45fa43922a

I go to a hobby shop, get a plug that mates with the one on the battery and wire it up to the fake battery that came with a charger for my camera. I don't modify the plug on the battery at all. Tape the battery to the tripod handle or leg when shooting. That way it plugs into the unmodified charger when I'm done, and it charges in about the same time it takes me to upload the CF card to the computer (just minutes).

I have been using the 6800mAH version of this for a year. It's been very reliable and very lightweight.

I've been using the 9800mAh version, works well.
I have more of a preference for the hard case version though, as it is a little more robust for field use:

Post Re: 30,000 mAh Li-ion Battery
A word of caution, you might run into problems if you try to fly with a Lithium battery that has Ah over 8 (or 8,000 mAh). Basically Li-ion batteries with more than one gram of lithium per cell, or more than two grams per battery pack require special inspection, testing and labeling per UN regulations. Some countries may have additional regulations for Lithium batteries.

See the Flying with Batts here under Power, Power, Power.

If you don't plan on flying with the battery or traveling internationally, then no problems.

Rob is right - you'll need special labeling and forms filled out to fly with the thing. If you don't fly - no issues.

I'd be circumspect on warranty. Having dealt with several of these manufacturers, warranty isn't the best.

Damn I'm going on a photography/timelapse trip to West US in October and I thought it was no problem to bring my blue bricks with me.
I thought only those lead acid batteries were the big problem?

I have 2 of those blue bricks which are 9800mAh and another one which is 15000mAh.
Also have one of those black ones that has multiple outputs and is 6500mAh.

You mentioned "documentation", how do I get that?! :) lol

I cant wait to see FRAA in the news, all busted up by TSA for smuggling illegal batteries. hahahahahaha

Go pluck up a 4800mah off ebay for 20 bucks. I have 4 of them and they work great, i cant run chronos for days on one of those things.

Yeah,

I forgot that I also have the battery that I got with my Stage Zero, that's 2700mAh.
So that one, plus the 6500mA is an option.
Maybe I'll get one of those 4800mah.

Damn dude, I can almost open a battery shop lol

The link below appears to be a very good looking, light battery.
Does anyone have any advice or knowledge of the product?
Appears air travel friendly?
Would the auto-power-off feature be problematic for timelapse?

Does not say what voltage it is, I suspect it is only 5v if it is designed for iphones etc, so it would only be good for powering the likes of a GoPro.

Hi,

I've just bought two 9800mAh. This one : http://cgi.ebay.fr/ws/eBayISAPI.dll?Vie ... 1497.l2649

It seems it's the same manufacturer than yours.

Have you tried to charge it with other charger than the one sold with the pack ? I ask it because I want to find a way to charge it with solar panel. Any help ?

:)

Most solar regulators are designed to work with lead-acid batteries, and will put too much voltage into a lithium pack.
You would probably be best off to use an in-line voltage regulator with a solar panel that is adjusted to the same voltage as the AC charger (about 12.0v?) as opposed to the 14.5 most solar regulators put out.

Post Re: 30,000 mAh Li-ion Battery
Thanks for your help.

I have a 12V / 5W solar panel with 280 mA nominal current. Do you think this regulator would be a good solution :
http://cgi.ebay.fr/ws/eBayISAPI.dll?Vie ... 1497.l2649

And, what happen when the pack is full charged ? What will do the regulator of the power sent by the solar panel ?

:)

Post Re: 30,000 mAh Li-ion Battery
Yes, one of those should do it. Once the battery voltage reaches the same as the voltage out of the regulator current effectively stops flowing.

Thanks a lot ! I'll try it.

But my solar panel is 12V and not 12,6V. Do I have to buy a 24V ?

Post Re: 30,000 mAh Li-ion Battery
Most solar panels that are rated at 12v will actually put out about 18v in full sunlight, that is why you need a regulator, so as to not cook the battery by overcharging.
Check the specs on your panel, or better yet put it in bright sunlight and measure the voltage coming off it.

Thanks again. And to finish : do you think a simple regulator 7812 would be good for that ?

You are probably better off with the regulator in the link, hard to beat a 97% efficiency in power conversion.

Post Re: 30,000 mAh Li-ion Battery
Do you guys place those batteries in parallel when connecting to your camera? I'm thinking of getting a three or four of them and linking them up to provide power for a long shoot.. Just wondering if thats what people normally do.

Post Re: 30,000 mAh Li-ion Battery
You can hook them up in parallel, but unless the camera is going to be unattended for a long time, I'll generally just swap battery once a day when I check on the camera.
The 10Ah version will last well over a day, so I'll just swap the battery then take the other one away to charge it for a multi-day shoot.

You can also use these -> http://www.hobbyking.com/hobbyking/stor ... ible_.html

I do a lot of drone building and therefor I have some knowledge of LiPo batteries.

They are smaller, lighter and way more powerful then any other batteries, especially Li-ion once on the market. You need a special charger indeed but considering that they are 1/3 of the weight, not to mention much cheaper it would be worth looking in too.

I always check-in these batteries and never had any problems with them.

Paul.

For those Lipo batteries, how are you running them with your set up?

Questions:
How do you adapt those to a regular DC jack?
Also are you running them in Parallel?
What do you charge them with?
Are they really 10000mah+?

They seem really good!

I cut all the non-standard connectors off all my gear and replace them with standard 2.5mm DC pugs/sockets so I can use it anywhere in any configuration
I have a number of DC-DC converters that will convert from higher voltages to 7.5 volt for cameras, have a look on ebay, they are cheap, about $5 each for the circuit board.
Charge them with the charger they come supplied with
I suspect they may not be exactly 10,000mAH, but most batteries overstate their capacities. I have found they do last longer than a 12v 7.2AH lead-acid gel cell though.

Post Re: 30,000 mAh Li-ion Battery
So you convert voltage - you don't run them in parallel?

Would something like this work? I don't know much about this...
http://www.ebay.com/itm/DC-to-DC-Conver ... 3a6a1ecf0a
http://www.ebay.com/itm/Mini-DC-2-5-6V- ... 5654389638

Hmmm, reading up more on lipo... seems like battery maintenance is hardcore right now!
So much more than lion!

Thanks!

Hmmm... just had a thought - what about using those sony NP-970 batteries?
They're rated for 7500 maH and they've got to be better than those blue bricks...
If stepped up to 12V, would it be a better option?!

I've been using ones like this to convert from 12v DC batteries down to about 7.8 volts for cameras
http://www.ebay.com/itm/LM2596-DC-Step- ... 1e78fabd85

The ones you have links to should be fine too.

Those actually look pretty good Derek.
Would be very handy to know you are connecting the right voltage to the right piece of gear at a glance, and to check on the battery charge status.

http://www.ebay.com/itm/170937990572?_t ... EBIDX%3AIT here is an 8,000mah li-po. I am not a big fan of li-po because they are really dangerous, if you need 8-20 amp hours try going with a deep cycle wheel chair battery http://www.batterymart.com/p-12v-18ah-s ... 7AodviQAhA They weigh 15lbs, kinda heavy, but less than a 600L !
