I have a Multiplus 12/2000/80, and a BMV 712. As I understand it, the temperature sensor should be connected to the negative terminal of battery bank, as it gets hottest there and is a better representation of the battery bank temp overall and recommended in the multiplus manual. I also have heard that there should be NOTHING between the negative battery terminal and the battery side of the shunt.
So my first question is: where should the temp sensor (that comes with the multiplus) go?
Question 2: I purchased an additional temp sensor for the BMV 712 (part # HQ1813), but I'm now wondering if I need it? Should both the Multiplus and the BMV712 have individual temperature sensor's?
Question 3: My battery manufacturer came with a temperature coefficient (24mV/C*). I have no idea what that means, but when I set up the custom charging parameters can i input it to give the multiplus or BMV 712 more data to properly charge my batteries ( (2) 12V 116ah at 20 firefly oasis g31's). 14.4V absorb, 13.5V float.
Thank you kindly,
