It sounds to me like your drive system draws a lot of current when attempting to turn. As you wear down the battery, this is more and more likely to throw the Jaguars into a low-voltage fault protection (indicated by the flashing red).

I would guess that the Jaguars are not damaged. Many teams roll un-powered robots around like this. You will see enough power back-fed into the system to light up the Jaguar LEDs, but in my experience it is difficult if not impossible to back-feed enough voltage/current to damage things.

The potential solution(s) would be make your robot easier to turn by reducing friction on one or more sets of wheels, reduce the current draw by increasing the gear reduction (less speed more torque) or if the system works OK for 2.5 minutes of driving on a fully charged battery, be prepared to swap batteries every match.
