Danny,
There is also an "L" shaped terminal that has a hole for mounting on the Jag or Victor. They are available from Digikey. Check my electrical presentation on the WPI site for pictures. This is similar to the old fuse block outputs. You use push on terminals to mount on the tabs you add to the controller. We use them on both input and output. It makes changing a dead controller into a two minute job.
Mark, you are not pushing the robot at a fast enough speed to force 12 volts backwards into either controller. A battery so connected not only forces 12 volts into that path but currents may exceed the output FETs specifications. Remember the current flows through the diodes internal to the output FETs.
