    Depends on if you want to risk it on a 11.1. Is the gun the CQR or the regular series? I would recommend a 7.4 25c for a CQR and a 11.1 20c for a regular series. This is the max I would do. If it was me and let's say you have a regular KWA I would use a 7.4 30c lipo and not go over that to save the life of my piston and gears. For me its not worth the extra ROF.

    Unless your gun is wired with a MOSFET, use the 7.4v, if you install a MOSFET, then you can run a 11.1v battery safely.

    7.4v 30c=9.6v
    7.4v 20c=8.4v
    The c is the discharge rate. It tells you how strong the battery is. A 40c will be substantially faster ROF than the 20c. Get a balance charger, mosfet and lipo sack. I haven't picked up a lipo yet but I've researched them. Buy off www.Hobbyking.com, use their US WAREHOUSE so you get very inexpensive shipping. Mosfets can be made by you or bought online. We have a guide on here to make one. Some users on here also sell some. KWA is reliable enough to use your choice of battery.

    What you say is barely a half truth. A 10C 5000mAh battery will put out 50A, while a 30C 1000mAh battery will only put out 30A. A 7,4v li-po won't necessarily give the same ROF as a 9,6v ni-mh. A 20C 1000mAh 7,4v li-po will give a significantly lower ROF than a 3000+mAh 9,6v ni-mh battery. Electricity works the same way no matter what the source is.

    The reason people often see an increase in ROF when switching from a 9,6v ni-mh to a 7,4v li-po is because they have been using a low quality <1600mAh 9,6v ni-mh and then get a high discharge 7,4v li-po. The high discharge 7,4v li-po will then have less voltage sag than the 9,6v li-po, resulting in a higher effective voltage delivered to the motor.

    Back on topic: If you want uber ROF, get a high discharge 11,1v li-po, if you want your bone stock KWA AEG to actually last, get a 7,4v li-po.

    so i have a KWA KM4A1 if i want a high ROF i would get like a 11.1 1,800 or 2,000 lipo with a high discharge of like 20c or 25c it would give me a high rate of fire.

    And also would a 11.1 would it wear down the gears in my KWA it and how long would my KWA last.

    Yes, if you want a high rate of fire get a 11.1v LiPo with at least 20c discharge rate and 1600mah+, however this will wear down your internals significantly faster than a 7.4v LiPo with a 25c discharge rate and 2200mah

    Depends how much you shoot, probably not the whole 8 hours.

    I want to get a 11.1 lipo battery 2,000mah 20c of 25c battery to fit either a peq-15 box or a battery.

    That battery should definitely get the job done, but I wouldn't run it with a bone stock gun. It will probably hold up, but you will be running the gun at it's limit, so you risk causing mayhem inside your gearbox. The fact that KWA recommend using an underpowered battery shows how much confidence they have in their design...
