Quick Change battery Tray

[Metallover]

The best thing I could think of with all the quick change battery threads is a hardcase pack (or something similar) that had indentations on it that would clamp onto the chassis.

Pick up a regular TV remote. Take off the battery cover. Imagine the cover is the battery and the remote is the chassis. One end of the battery slides in and the other end clamps on. You may be able to incorperate the leads with this too if you are creative...
