Here is a graph from today. It initiated the first charge cycle after I set the absorption voltage to 55V and the monitoring voltage to 54.9.
It raises the voltage to 55V around 13h’ish and very soon it sync’ed to 100% charge. This is what I hoped and expected.
Then it keeps the voltage at 55V forever, at least till 18h, also as expected, but not what it should do. I expect it to lower the voltage when the cells are balanced. They were balanced all the time as one can tell from the min/max cell voltages.
I think that both bugs are (again) clearly demonstrated. At the same time, there is a third bug, namely that I lowered the SoC level at which it must start a full charge cycle to 50%, but it still does so at 70%. Most likely because this setting is duplicated and not synchronized. Maybe that is already a topic; I will look for it.
