I've switched to using Nickel Metal Hydride batteries rather than the nicad shown.
NiMh batteries offer better duration and aren't all that much more expensive.
you'll also need some 18-20 gauge wire.
That is Ty Brown's SM 79 in the picture of the mounting. I've seen this done by Dave Platt and the pix come from Ty's post on another web site.
Here is a shot of the battery, charger and homemade charge lead I use.
