Hi,
in my boat I've got a BMV 712. It shows my batteries are at 100%soc, but the voltage is dipping to 12,2 this winter. How come it's still 100% SOC with this voltage?
And another question, since the beginning, the BMV is not giving any temperature. Tried flipping the power and the temperature cable (don't see any difference). Is there a way how to get this working
