- This I just finished installing a REC 2Q BMS, Cerbo GX/GX 50 display. I have an existing Victron Quattro. I configured the Cerbo for DVCC. I got it all online and cells charged. When I turned off the BMS the Quattro went to bulk trying to charge the now disconnected pack. I quickly turned off the Quattro. Obviously this is not desirable. I don’t see anything about how to resolve this in the Cerbo manual and don’t see in any settings in the Quattro that would prevent this. It seems that when the Cerbo loses communication with the BMS, the Quattro reverts to its programmed charge algorithm since DVCC is no longer available. Please advise. Thanks!
