I designed a better battery case for a single 18650 battery because I wasn't satisfied with the others I found. This case features a large, easy-to-grip cap and a chunky design that prevents it from rolling away. The extended threading allows for secure fitting, even accommodating protected batteries that might exceed 65 mm in length.
