If low charging rate is desired, you should use the BREAK-IN mode. Charging in that mode is terminated by only time (1.6 times battery capacity) and temperature.
It is normal for the charging capacity to exceed battery capacity by as much as 30% depending on battery brand and charging rate.
This does not cause any harm to the battery as the charging rate is very low (only 10% of the battery capacity).
Each module is fitted with its own, personal electronic management system to optimise its charging and discharging rates.
