Hi. I have a Victron BMV-600s on my Mountain Trail camper trailer. I am running 3 x 105Ah full river AGM batteries for a total of 315Ah. I have done some testing over the last couple of days running my 80L Waeco as a freezer, and have found that the SOC doesn't seem to be displaying correctly. The V is 12.13v, the CE is -37.5Ah, yet the SOC is still showing 93.5%. Any ideas on how to rectify the incorrect SOC? Thanks.
