No Page not exactly here is the space size limits:
70mm Wide X 100mm Long X 19mm High, It is JUST enough height to fit six of the 18650 batteries as you can see by the photo. I drew the black line with a sharpie to show halfway point. And there is a picture of the circuit board they attach to. So I could attach six of the 18650 batteries with some wiring, shink wrap and patience and I think still get the case to close. It will be right at the limit of the height. Maybe it will have a wrap of gaff tape or extra large shrink wrap to ensure it is solid, we'll see.
