Maybe it will clear up or an administrator can remove that link so the rest of the thread can be accessed.
As for the enclosures, I searched every source I could find for something that came even close. Nothing had the convenient size, button placement, and battery compartment like his design. Prismatic lithium batteries are used everywhere, yet none of the names I contacted sold an enclosure with a built-in compartment for them. Adding a few contacts makes them perfect. Maybe when the attachment/dangerous-link issue is resolved, I will add a picture and link to the contacts I used for my battery PCB connection.
