    Hi Jonathan,

    For the charging process of battery, it has the CC/CV characteristics, when charging in CC phase, the charging current is constant, when the voltage reaches the CV value, the charging current will be changable and drop to terminal current.

    The charging current you set in learning cycle is the CC current, during this phase the current is constant, but after that, the current will be changable.

    Thank you.

    Best regards,
