Step 2Prepare the battery holder
Since the CCFL driver board takes12VDC and then steps it up (I think I read 670 volts), It takes 8 1.5 volt batteries. This is a lot to cram into a bike's wheel, and if I had it to do over again, I'd have got to the store and bought one of those little 12 volt batteries they use in wireless doorbells, or just used a stack of button cells. Sure, it wouldn't last as long, but it would be much lighter and smaller.
I ended up hot gluing a couple of battery holders back to back. A couple of quick touches with a soldering iron and some wire, plus the addition of my pushbutton switch, and the battery pack was all ready to go.
