Aspects of the disclosure include a battery management system that actively limits the operational voltage of a cell to avoid a cell pressure surge in response to an indicator of battery cell degradation. An exemplary battery management system can include a memory, computer readable instructions, and one or more processors that perform operations that include: measuring a first cell pressure of a cell of the battery pack at a reference voltage and measuring a second cell pressure of the cell of the battery pack at the reference voltage. A moving average of cell pressure progression is determined from the first cell pressure and the second cell pressure. Responsive to the moving average of cell pressure progression exceeding a cell pressure progression threshold, the cell of the battery pack is identified as a degraded cell and an estimate of remaining cycles for the degraded cell is determined.
