There are a lot of misconceptions about LiPos by airsofters, but LiPos are vastly superior to both NiMH and NiCad batteries. I have run all of my AEGs on LiPos exclusively for some time now, and will even be installing one in my TM AEP when it arrives. If you are tired of low ROF, death in the cold and after just a few hundred rounds, long charging times, and bulky batteries, then you should consider switching to LiPos. They are not dangerous unless you do something stupid, and they are not expensive. Also, they are not all absurdly more powerful than NiCads and NiMHs.

I've been using them for over a year with no issues what so ever.  I even completely drained one by accident once, which you're not supposed to do, but it's still working just fine. 

If you don't want the really high ROF, get a 7.4v.  It fires like a 9.6v.

When a gun says it come ready for LiPo batteries, is that just a trick to get you to buy it or could I put in a 7.2v into my KWA SR 12 and it will be fine?

That's mostly just marketing. Anyone can hook an 11.1v 30C lipo up to a gun and use it, but it's unlikely to last. If you were to use a decent 7.2v, it would be very much like running a large 9.6v NiMH battery. You'll have all the power of the huge 9.6v, but it will be in a much smaller package.

In short: Yes, you'll be more than fine with a 7.2v lipo in your KWA.

As far as my experiences and observation go for KWA guns, I believe they are fine with 11.1v Lithium Polymer batteries.
To give you a visual example, I've once watched my buddy emptying 10 mid-cap mags one after another, each holding 120 rounds, on full-auto with an 11.1v battery. That is total of 1200 BBs give or take.

However, airsoft guns, with no exceptions, will wear down eventually, even those manufactured by Systema.

KWA recomends no more then a 11.1v 1600mAH 18A lipo. So a 7.4v lipo will not hurt the gun any more then a 9.6v will really.

Here are some videos that Allizard and Spiggy from KWA made. Of course these are for testing the battries, but it still shows that KWAs can stand up to a lipo on continuous fire, though I don't think it it is recommended.
