Here's how my experience with batteries went down (I have a KM4S-System):
-Bought gun and 10.8V nunchuck style, not a chance of it fitting.
-Bought a 9.6v 1600 mah mini-style battery, and still no go
-Modified the internal wiring: Re-routed wiring over top of the barrel on the left side, and coming through to the bottom side of the barrel on the right side. This eliminated a lot of excess wiring in the foregrip area
-Tried 9.6V mini again, no go
-Removed the fuse holder, but kept the fuse for safety (Kinda looks sloppy now, but I still have the protection of a fuse and I can peep through the vent hole near rail number 25 to see if the fuse has popped). This further increased the available space for a battery. i'll work on cleaning this up, but it's 100% functional right now.
-Tried 9.6v mini again, no go
-Mutilated mini battery: Removed plastic end caps, removed about an inch of wiring length, re-wrapped battery in black electrical tape for a sleeker look
-Result: Perfect fit.
What would I do in the future? First, I would recommend to KWA to eliminate a lot of the wiring in the fore grip area. It isn't needed, it takes up battery space, and it doesn't look clean. Second, start with a mini battery pack that doesn't have plastic end caps. And third, buy the right tools. My Sog Seal Pup took a beating on this project.
