  "textContent": "A battery system includes a battery subpack having first and second battery cells, a cell monitoring circuit, a RF transmitter, an RF receiver, a subpack microprocessor, and a first transceiver. The circuit measures a voltage of a first battery cell. The system includes a master controller having a second transceiver. The RF transmitter sends a voltage value corresponding to the voltage of the first battery cell to the RF receiver. The subpack microprocessor determines the first battery cell has an overvoltage condition based on the voltage value and sends an overvoltage message to the master controller via the first and second transceivers. The subpack microprocessor induces first and second subpack contactors to each have an open operational state when the master controller sends an open command to the subpack microprocessor.",
