A battery system includes battery cells and a control circuit having a control pin. The control circuit determines a condition of the battery cells according to cell parameters of the battery cells. The control circuit compares a voltage at the control pin with a first voltage threshold to select an operation mode from a first mode and a second mode. In the first mode, the control circuit compares the voltage at the control pin with a second voltage threshold and generates a control signal based on a result of the comparison, such that the control signal is generated if the battery cells remain in the condition for a time period that reaches a first time threshold. In the second mode, the control circuit generates the control signal if the battery cells remain in the condition for a time period that reaches a second time threshold.
