Either it is faulty or ??. Might as well use the built in meter in the trailer.
That seems very odd. Is it reading 12.3 volts under a heavy load? How many Ah are consumed? Is it reading 100% after no usage or after boonidocking?
Has it ever worked properly? Can you take it back to the place you had it installed?
Sorry for so many questions but I'm sure there is a reasonable explanation for why it's not reading correctly. Our friends also have the same BMV702 and find it incredibly accurate too.
I'm sure this forum's collective minds can help resolve this dilemma.
