The first thing you should worry about the voltage of the cells: If one of them exceeds the max allowed (or recommended) charging voltage, which is usually 4.2V, then this cell will degrade more. A 200mV (5% of max voltage) of exceed may result in 20% faster life degradation. how much could they disbalance after one cycle?
When all LIB cells are consistent, the SCPB pack produces slightly larger power energy than the PCSB pack. However, when one LIB cell is defective, the PCSB pack shows better performance compared with the SCPB pack. An inconsistency within lithium-ion batteries (LIBs) in a battery pack can lead to reduced power as well as short cycle life.
