I currently have a BMV-712 installed in my Travel Trailer, and I have upgraded the batteries to a pair of 6V deep cycle golf cart batteries. I am currently using the auxiliary input to sense midpoint voltage of my battery bank.
In the near future I plan to install a SmartSolar 100/30 MPPT charge controller, and I have read that it can read the temperature and I believe voltage from the BMV-712, and adjust it's charge parameters accordingly.
In my case, I only have one possibility, temperature or midpoint voltage as an option. Is it more beneficial to sense temperature or midpoint voltage? Is there a way to sense both, such as the Smart Battery Sense?
