For battery pack in charge and discharge, the available capacity is limited by the cell with the least capacity. Due to the heterogeneities between cells in pack, the charge throughput of individual cells is different. Thus, cells in the pack are degraded differently. For battery pack of 18,650 cells in parallel, the difference of their available capacity can reach 3%. This difference accumulates with time and accelerates degradation of the battery pack.
