LED lights battery pack

Alright, so my friend and I are working on Tron Sora and Riku; we've decided on using LED's to light up the cosplay, but we're having trouble finding a battery pack/power source.

These are the lights we have ordered, and she says we need a 12VDC battery pack to power it (if it's wrong, please let us know!).

All we can find at an affordable price require an AC outlet, so we're kinda stumped on where to look, so if you can point us in the right direction, that'd be great

What Million Knives said

You can easily find this at any electronics store namely a Radio Shack or a Fry's Electronics.

Pick up a soldering iron while you're at Radio Shack.... and maybe some flux.

Oh, is that really all we need? My friend asked someone who worked with them before and they said she'd need something else, but that would be so much more convenient ^w^;
Thanks for answering!

I think the full shopping list is-

-LED strip
-Battery pack
-Maybe a switch so you can easily turn off the LED's to save battery life
-wire to go between battery pack and LED strip (with a switch in the middle, if desired)
-Soldering iron
-solder
-flux
-electrical tape or heat shrink tubing to cover wire splices
-whatever items you need to attach the pack, LED's, switch, and wiring to your costume.

As noted by djlemma

What do you have exactly as we can they tell you what you need.

My friend and I aren't anywhere near eachother, so I'm not too sure what she has, but...I don't have anything yet. I've read up on soldering the wires, so I think I understand what I'll need and what to do, but that's all from various tutorials I've pulled up on google. I forgot about switches actually, I was supposed to look those up forgot all about it since I'm used to seeing battery packs with built in ones used in tutorials.

Basically my friend and I have a fairly vague understanding of what to do but we've looked at many tutorials and understand the wiring stuff, it's just we're unsure of everything we will need. So djlemma, thanks for that, that really helps! Would someone mind explaining what flux is?
I really appreciate the help!

For 12V, you just need something like this (provided you use Alkaline batteries and not rechargeables). If you use rechargeables (NIMH type) it will only be 10 to 11 volts which might still be okay, but might not.

This one has the wires already there, if you find one (ie. at radio shack) without wires like the one that Millions Knives posted a link to, you will likely need to get a 9V 'snap connector' also (radio shack has these) ie.

Flux is an acid that you put onto copper to make the smooth surface a bit more porous. It's kind of like taking sandpaper to a piece of plastic before you glue it to something.... The rougher surface of the copper will suck in the solder and make a much better joint, and it'll be tons easier to solder together as well.

Whenever you cut that LED tape (there are specific cut lines, as I'm sure you know) you have to solder wires onto the little copper pads on the tape. Those little pads, in my experience, don't like to be soldered onto unless you put on a little flux first. Once the flux is there, it's easy. Heat up the pad, put a little solder onto it. Heat up the wire, put a little solder onto it. Put the wire and the pad together, heat them both up, the solder will melt together (add a little if needed) and boom, you have a solder joint.

Just wanted to say thanks for all the help!
My friend and I got together last week and started adding the lights, and I got most of them all soldered over the weekend, and aside from accidentally burning some things, it came out pretty well; this is what I got so far

Agreed, very nice!
Anything that lights up gets bonus points in my book.
