Would a 3.6v 1600 mAh PSP battery work in a Xbox 360 controller? i happen to have an extra battery, not circuit, on my desk and need to do something with it. I know i can get a plug and play charge adapter from game stop or amazon to charge it, also. It only has a positive and a negative pole. And also, if its helpful, the controller will either be a matrix or cg, not cg2. Thanks!
