AX2550 led displays '8

My AX2550 stopped dead in its tracks yesterday and displayed the \'8 on the led. No resetting worked and it wasnt until I brought it home and plugged it into the PC and hit repair on Roborun did it snap back and display no control. Fantastic that the repair was a very quick and unexpected 3 seconds but what caused it to stop and display \'8? Batteries, two 12 volts in series and the seperate 12 volt to control the brain while linking to the remote control were fully charged.

Possible suggestions as to what caused it would be appreciated.

if the controller is not damaged, a solid 8 usually indicates an undervoltage or overheat condition.

A 12V supply on the Power Control input should keep this from ever happening, but beware that 11V at the input is sometimes sufficient to trigger that fault.

There is nothing special about connecting the controller to a PC. So chances are that the controller would have returned to life anyways.

my 12 volt battery had 12.79 volts and my series batteries had 25 volts. Could that have been too few volts and when under load stopped the robot? How would the controller automaticly return to life? Everything has been so reliable to this point and I have changed nothing in my routine of charging or running the robot.
