A battery system is described, comprising a battery management unit, a battery cell monitoring unit, at least one battery cell and a safety electronics system for the battery cell. The safety electronics system has a first comparator and an alarm signal output for an alarm signal. The first comparator compares a battery cell voltage of the battery cell to a predetermined threshold voltage value and generates the alarm signal on the basis of the comparison. The battery threshold voltage is lower than the battery cell voltage in normal operation and higher than a critical voltage value. In addition, a motor vehicle with the battery system is described, the battery system being connected to a drive system of the motor vehicle.
