Interested in making your own mini Power Battery? I decided to make a quick tutorial for how I made the Blue Lantern. You can follow these same steps for pretty much any Lantern (except for maybe the Indigo? I'm pretty sure they're batteries are their staffs, so yeah) just changing the color and shape of handles/base and top as needed.
And I should give credit where it's due - I borrowed the design for my lantern from these great CG models
