This can hold one, two, or if you make it a bit looser, even three 3V button batteries. Button batteries are a wonderful shape and size for integrating in soft circuits, but they don’t last long in combination with conductive fabric traces, plus they are not rechargeable.

9V Battery Pouch with 3.3V Regulator
This holds one 9V battery and regulates the voltage to 3.3V. It is useful if you are connecting to xbee or lilypad.
If you change the 3.3V Regulator (LD1117V33) to 5V Regulator (like LM7805), it can be used to provide 5V for your circuit. In that case, make sure that the pin configuration of your regulator is matching to the pouch arrangement. Check the datasheet of your regulator. For details of sewable 3.3V regulator, check this post.
