We are sticking power over USB, so the LiPo with the JST won't work. I'll have pictures of the case tomorrow, but pretty bad. It was a hinged design, which allowed for a larger solar panel, but it ended up being way too thick. Of course, we already saw this in CAD, but after cutting it out and holding it, it's even more apparent. We'll need to stick to the 2W panel, unfortunately.
We do have a source of reliable cables, which will eventually be included.
