I recently picked up a Momax battery charger from ebay :
http://cgi.ebay.com/Momax-Battery-C...AU_MobilePhoneAccessories?hash=item2304be6824
It has been very useful to me as I already had a few spare batteries. I now take it with me when a travel instead of the genuine charger and I can easily keep all my spare batteries charged . I always have a few spare charged batteries with me just in case phone usage is high during the day. It also has a USB port and can charge the phone in a convention way or even other USB devies like IPods etc. Recommended!
Any third party extended battery options for the S7? I prefer the slim version if possible.
Sent from my SGH-T849 using XDA App
I rigged up a battery pack using 4 rechargeable Energizer AAA's and just plug it into the DC power socket and double-sided taped it to the back of the unit
I imagine I could use some left over spare Li-Ion batteries from other phones though.
UPDATE: someone asked how
STEP 1: Buy something similar to this http://www.littlebirdelectronics.com/products/4%2dAAA-Battery-Holder.html
STEP 2: Buy a male plug that fits the female power socket on the S7 Like this but the correct size http://www.littlebirdelectronics.com/products/1.3MM-PLUG%2d2.5MM-SOCKET-DC-ADAPTOR.html
STEP 3: Solder them together so that the + and - charge come out of the same wires as the wall-charger
STEP 4: Plug in batteries
If this looks/sounds difficult, don't even attempt it, you WILL break your tablet.
Since the original battery do last too long, i found this 2 option that i think that work with S7:
Good price and free shipping
lol i cant post links yet, sorry guys...
here goes the links for the battery extender....

Nice guys! I was searching for an internal battery solution.
These battery packs look nice but be carefull, the output is only 500 mA. The S7 charger is a 2amp output charger. I'm not sure how well it will run on a lower input.

The DC pack will only feed what the unit draws, and I doubt very much that it draws the entire 2000mA.
I have rigged up a USB charging cable for myself, USB pumps out 5v at 500mA max per port (I'm only using 1) and it charges a little slower than from the wall, depending on which computer I'm charging from, but apart from that it works great still and I can use the same cable to charge from other USB-charging devices like the one I have in my car.
The 500mA output will just mean it charges slower, and seeing how it's only a battery extender (IE, the oem battery is still required) and not a charging solution (the S7 can run without the battery off only the charge from the wall), the charge provided will be fine for extending the battery life.

500mAh as supplied by standard USB will charge but as you say only slowly.
It will not start a charge if the battery has been allowed to drop too low. That's common with all Lion batteries and is why you get a high current wall charger to do the job.
If you are using the device at the same time (and depending on the functions in use and the state of charge of the battery) you will definately struggle with any positive charge and will experience heat build up in the USB port, cable and device so be carefull!
If you are also using the device as a phone and get a call there will be an extra high peak current draw that has to be contended with and that complicates things further.
With all the tests that I have done allong these lines 1000mAh is a bare minimum to cope with eventualities and even then it's borderline.
I have blown car adapter fuses and had low current phone chargers get really hot.
I now only use 2000mAH rated chargers.
Are there any? I would really want to have a battery that could last at least 6 hrs... Any suggestions?

Energizer XPAL XP18000
That will give you about an extra 12-18 hours,
But no internal battery larger than standard. Why would you want one when the external packs are usable with any device and don't become redundant when you upgrade to a different model?
I made such a battery of two packages of Chinese Tablet battery voltage of 7.4V LiJon / 1500mAh connected in series and used a converter on the circuit LM2576 (with car charger navigation) [//chomikuj.pl/wibi) -> Huawei Ideos S7/Dodatkowa bateria]. This additional charger to recharge your battery voltage 8.4V. Pictures and diagrams from the following link will explain everything.
Does anyone have the isound 16,000 mAh battery. I have heard good things about them and bad things about them but it seems to be one of the few external batteries to can push enough current to charge the flyer. Now sometimes the charger is charging the tablet, sometimes it isn't... the battery is draining. My question is, is there something in the flyer that lets it know when it is charging by usb and limits the current that it can draw? When I use the htc charger it dosent have a problem charging. Is there an after market charger that will adequately charge it... or do I have to go back to HTC?
Yes, the fly knows if its charged via USB oder carger.
The carger has 9V @1,2amps and no standard microUSB plug.
Charging via USB means charging via 5V @0,5amps.
Charging via an external battery is no problem, but of cause much slower than the original carger. (about four times).
(I use a external battery with 5000mAh from DX Power without problems)
I recently bought a 1900mAh anker battery for the Sensation and I plan to use it for my Amaze.
On the battery it says that the limited charge voltage is 4.2V and on my charger it says that its output is 5V. Does this mean that I should not charge my anker battery with my charger? Or will it be fine?
It will charge fine. I have 2 anker batteries.
Hello, i just bought this extended battery for my i777 and i was looking forward to use both the OEM 1650mAH and the extended one together.When one is out of juice use the other while it is being charged in an external charger...and vice versa.
Will the i9100 extended battery work with i777?
Will this external charger work fine???
how do i connect the battery with the pins on the charger???
How will the charging time vary for both 3500mah and 1650 mah battery with the external charger???
i want to avoid plugging my s2 as often as possible to the ac directly in fear of damaging my new usb flex cable.

An i9100 battery will not work with the i777 battery as it needs 4 contacts (the 4th one is for NFC). Here is the source: http://forum.xda-developers.com/showthread.php?t=1286746 and read post #5.
