Because of design constraints I need to charge a 2S Li-Po battery over its balance connectors using a single-cell charger IC (e.g LTC4002). In order to allow the user to interrupt the charging process before the battery is fully charged, it makes sense to charge both cells alternately so that they are not significantly unbalanced after the interruption. The switching would not be triggered more often than every few minutes.
How harmful is such behaviour for the particular battery technology? Would you suggest some other charging process under my constraints?
Thanks for your help!
