Matrix High Performance 11.1V Stick Type Airsoft LiPo Battery (Model: 1450mAh - 20C / Small Tamiya)

"First of all, this LiPO stick battery actually is round just like the regular NiMH stick batteries even though it looks squared off a bit at the top in the picture. BUT.... this battery is like freakin 1mm wider in diameter than regular NiMH stick batteries. I kid you not. I'm absolutely sure that the manufacturers of this battery tried to make it the exact finished diameter of existing stick batteries but that after their manufacturing process it came out in finished form 1mm wider in diameter after they got it together and wrapped up in the plastic. This battery will NOT fit in the tube of a CYMA AK 47. I tried and tried. HOWEVER.. it will STILL fit under the cover of the battery compartment! You just have to situate it just right and put the tamiya connector over on the side around the bottom side of it. It just barely fits. Thank God. Cause I hate trying to return stuff ordered from the internet. The battery itself works great. I gave it only 3 stars cause of the fit problem. Someone really needs to contact the Matrix Co. and inform them of their screw up. Otherwise, great LiPO battery.
