The batteries Brick suggested are good.  There is an 11.1v version which works well.  It's only 1200mah though.  But they're pretty cheap so buy a couple or something.

No, it's not.  Out of spec is also a somewhat relative term.  As long as you don't go above 20-25C, stay at 11.1v or 7.4v, and stay at a reasonable mah (not like 6000), and you have a fuse as well, you have nothing to worry about.

Essentially, if it fits in the stock and is of reasonable voltage, you're good.

Well if you don't want the free cell battery, and you don't want to go to 25C, here is the brick lipo that used to be sold in the pro shop. They're a little pricey though.

http://www.airsoftfi...Battery/138633/

But understand what makes something "out of spec."  The amps the battery is outputting is the C x mAh / 1000.  The battery KWA recommends is a 11.1v 1600mAh 18C, or 28.8 amps.  The voltage of the battery is a different subject.  

Forgive me if I'm using incorrect terms, it's been a while since I've dealt with this or had physics.  

The 11.1v I linked you to is 30 amps.  That isn't going to blow anything whatsoever.  I've actually had better results with it than a battery of the same specs as the one KWA recommends and used to sell.

Off of the 11.1v 1200mAh 25C I use, I don't know exactly because I've never had it die on me while playing.  My SR10 is fetted to semi only shooting 540, so I take a lot less shots but it's going to take a bit more juice to get the gun rolling.  I'm guessing I can get about 1000-1100.  That's a rough guess.  It could be significantly more or less.

Don't forget that you can't just run a LiPo all the way down like a NiMH.  I'm sure the battery is capable of pushing out upwards of 1100, but the voltage of the cells will go below where it should be and damage the battery eventually.

I plan on fetting the gun would a buffer tube lipo and mosfet in tube fit

Highly unlikely.

The lipo should be easy enough.  But how do you plan on putting the mosfet in there with it?  I suggest you use a crane stock if you plan on having everything in the back like that.

If you don't have a crane stock and your gun has a handguard or PEQ you could run the wires up there and stick the fet in there. Similar to the way the battery fits in KWA's discontinued KM4A1.  That's a little tricky though.

I heard the btc spectre is very small and can fit almost anything
