Capt Mike,
From the Dual Pro Manual:Each charge cable assembly is equipped with a temperature sensor located at the junction of each set of
ring terminals
To verify that I called their technical support. According to their tech rep the temperature sensor is indeed located where the two battery leads join, after the fuses. So this sensor is measuring ambient temperature, NOT battery temperature, which can be different. A set of batteries, in a boat, sitting down at water level, can be at significantly different temperature than ambient!
If I were using a Dual Pro I would try to get the sensor directly in contact with the battery terminal, probably using careful dissection technique to expose it from within the cable termination.
With today's electronics technology temperature compensation measured at the battery terminal is cheap and easy. I wonder why it is so rarely used.
Can anyone propose an argument, considering the physics of it, of why ambient temperature is a sufficient measurement?
John
