I finally sucked it up and rebuilt the eXKateCD (see previous posts for its story of misfortune). It has a Kelly KDS Controller, 9 new Lipos, wired hand throttle, and a KEYED battery selector that should prevent anyone we don't want from turning it on or plugging the battery in backwards. Check it out:

As it turns out, the KDS series of Kelly Controllers doesn't have Regenerative Braking, even though it is perfectly capable of doing regen. They just didn't include it in the software so they could charge twice as much for the series with regen....or they are so incompetent that they didn't realize they could easily make it do regen. Either way, the board doesn't have brakes, which is bad. A new motor controller will be designed/built for it (probably not by me considering all the other stuff I'm working on) that'll have wireless control via Xbee radio modules.
I thought I had more pics than this, but I couldn't find them.

1. Glue tires onto wheels (2 hours)
2. Component layout inside of battery box (8 hours)
3. Figure out trucks risers (1 hour)
4. Make hand-held remote control (2 hours)
5. Program motor controllers to take throttle commands from hand-held remote control (2 hours)
6. Test (1 hour)
7. LED lights (4 hours)
8. Waterproof / Loctite (1 hour)
I'd say this project is 80-85% complete at this point. But with DBF, Rocket Team, and classes in full swing, the last little bit might take awhile.
