This is a power bank enclosure. The front face and back face can be change. Space for the bettery is LxWxH-130mmX72mmX20mm . I used 10000 mah X 2 battery . So power of the power bank will be 20000 mah. Use hard plastic for the enclosure and front-back support. After assemble you have to apply glue to make front and back face secure. I didn't use led flash light in my design, if you want you can make a hole for the flash light. Otherwise you can contact with me.
