When charging with the Victron RS48 / 6000, I observed that there were brief overload peaks.
The Victron is set to an end-of-charge voltage of 54.1 V and today I noticed a peak of 58.05.
I use LiFePo4 cells
Is that normal?

Overload Peaks with RS48/6000
Do you use a GX device (like the Cerbo GX) and DVCC turned on?
That will overwrite the settings of the RS48/6000.
Which BMS-Setting (Remote Mode) did you choose? When you use a battery with a internal BMS without communication, try that:
"Remote on/off" with a default wire bridge from Remote_L to Remote_H.
I use a battery with external BMS and "Remote on/off" with a default wire bridge from Remote_L to Remote_H.
But the overvotage peak still appears from time to time.
In the picture above, the battery voltage is already higher (57,10) than the set absorption voltage (56,80): how can that be? The absorption voltage is actually the maximum voltage that the battery can have?
I'm just running the RS48/6000/80 in Demo mode on victron connect. I think that is why my changes are not applied to the demo picture.
Do you run your System with a Battery monitor like the BMV 702 or a smart shunt?
If not, did you connect the voltage sense wires VSENSE - (11) and VSENS + (12) to the - and + terminals of the BMS or the Battery?
grüße, hast du schon mal probiert mit weniger absorptionsspannung zu laden? Könnte sein, dass die Spannung pro Zelle etwas zu hoch ist bei deinen Lifepo's ?
Bzw was gibt der Hersteller genau an?
