My Victron IP65 charger charges a 100A 24V battery. In de absorption phase shows 28,3 volt. In the Lion mode the absorption phase must stop after 2 houts. But after many hours the absorption phase keeps on. With 0 Ampère. I would expect a float or voltage of 27V. What’s going on here?

Addition: the shunt indicates that there is zero current. Could it be that the built-in BMS closes the battery when it is full?
