So both my Quattro and BVM are remote from the batteries (about 3M but also over an axle so non-trivial to run additional wires).
I'm guessing that the BMV temperature probe is sensitive to voltage drop from extending the wires (assuming I can run them from the BMV to the batteries now everything else is installed).
So the Smart Battery Sense would seem to be a solution to provide temperature data for the Quattro via the VE.smart network. (Of course, a shunt that also did temperature for the BMV would be ideal!).
Is this possible?
