All true, but my Trimetric and another voltmeter on a long wire to the batteries reads high. No effect from anything else drawing high amps.
I used the Trimetric's program for that to lower its reading to be the same as I get at the battery itself with a multimeter (which has a new battery so it is not reading high like they do with a low battery) (I did have to allow for the Trimetric reading to only one decimal place so it didn't round up unless at 0.5 or above.)
Could the difference be in the location of the ground wire?
