  "textContent": "A propulsion system for an aircraft includes a battery, an electrical distribution system, a charger, and a battery management system. The battery includes a plurality of battery strings including a first battery string. Each of the plurality of battery strings includes a plurality of battery cells. The battery management system includes a battery sensor assembly and a battery management system (BMS) controller. The battery sensor assembly includes a plurality of battery cell voltage sensors. The BMS controller is configured to control the charger to charge the battery, including at least the first battery string, by executing a battery charging profile including a target charging voltage, measure a cell voltage of each of the plurality of battery cells of the first battery string, and identify correlation or non-correlation of a charging voltage applied by the charger with the target charging voltage.",
