Recently I have been working a lot with batteries recovered from disposable electronic cigarettes. This is a great source of li ion cells, but due to their unusual size(13mm x 40mm) I've not found any reasonable solution to hold them comfortably and safely and at the same time be able to check their condition and capacity. So that's why this project was created, it's not perfect, but it serves its purpose and is handy to use.

You just need two M3 screws (15mm - 25mm) a pen spring (4mm diameter) and two nickel strips. I recommend gluing the strips to the bodies with hot glue or superglue to make them stiffer.
