Hi All, I have just charged up fully my 2x170ah agm victron batteries. I noticed a discharge from 13.2 to 11.9 over last 12h period, is this normal? System is idle , pulling 3-5w when in idle state. Seems also to be a discrepancy with the soc showing at 99.6% now at 11.9v. Does this seem normal? Any input appreciated
