During the normal charging process, the device divides
the charging current between battery 1 and battery 2
as set. Once the battery 1 is fully charged, all the charging
current is fed to battery 2, regardless of the set value. If the
voltage of battery 1 drops, the charging process starts again.
If only battery 1 is connected, the entire charging current is
supplied to this battery regardless of the set value.

PWM charging frequency

The pulse frequency of the device can be set here. This may
be changed to reduce possible interferences.
