I just installed an LFP battery, and set up the BMV 712 per Victron parameters for LFP batteries. However, while the battery gives a direct reading of 13.51 voltage, the BMV 712 shows 13.40. Further, while hooked up to shore power I have a voltage reading of 14.4 taken from a 12V plug inside the trailer. Also, the Victron shows a SOC of 100%. Nothing seems to be synced up correctly. What can I do to get everything in line?
