Batteries-8s,10s,12s etc...
When people talk these size batteries are they really using say 2x4s/2x5s/2x6s etc or are there actually single packs this large?

a aingle LiPo cell is about 3.7V nominal.

When you put 2 of those cells together in series, you get 7.4V. or 3 cells in series is 11.1V, and so on.

The number of cells a battery has is represented by a number, followed by the letter "s", for example, 3s.

Here is a picture of a typical 3 cell lipo pack. As you can see, this pack has 3 cells. It produces a voltage of 11.1V nominal.

If you were to put this pack in series with another 3 cell pack identical to this one, (2x3s), the packs together would produce 22.2V, or the voltage of a 6 cell battery pack.

When you see someone write, "2x6s", chances are he has two 6 cell battery packs in series, both producing a total of 44.4V.

But, he MIGHT have those batteries in parallel. Say those packs were 5000mAh each (thats their capacity in milli Amp hours).
Two 6s packs in parallel will produce 22.2V together, but the capacity doubles, so together, there is 10,000 mAh available.

Maybe I didn't understand your question. It is a little vague. (I probably went overboard on my answer)
Are most people using 2 6s packs instead of 12s packs?
Yes, probably. 6s packs are just cheaper and provide a lot more flexability. But 12s packs really do exist.
