I'd moved my post to this section of the board:

I basically want something the size of that gray bag in the picture I posted in the above link. Something that can fit a battery pack with these dimensions: 6 x 2 x 1. Has to sit beneath the top tube (towards the front and not the back of the tube, so the battery wire can reach) and by "small", what I meant was that I don't want anything that looks like a 4th-graders backpack. No need to store keys, etc, just a battery.
