Re: Battery Draining

A very rare occurrence is a defect in the 120 amp circuit breaker. Gently tapping the red reset button will cause lights on the robot to flash. If this occurs, the breaker needs to be replaced.
Do you still have full lights on everything when the battery shows 0.0 volts? Does any of the battery wiring get hot? If so, it sounds like you have a dead short somewhere on the robot. Likely a speed controller has been wired out of polarity. Pull all the breakers except the DSC. See if the battery voltage stays up. If it does, replace one breaker at a time to determine the source of the problem.
