G&P XM177e1 battery?
 

I'm wondering if anyone knows where I can get a battery that will fit in the stock fore end of a G&P xm because other then getting one built I have no idea what I should do. note that the xm grip is smaller than the standard m4 fore end.

thanks, Matt

mini numchuck? or a lipo?
they dont include or at least say what type?

Edit:
google hooked me up, a mini numchuck size should fit.

well it led me to this butterfly type battery so i'll try it out and see what happens

turns out a 9.6 volt 2000 mah butterfly type battery fits!
