I installed 6 - 6V batteries in my RV, I added the BMV-712, and want to know if I can measure the midpoint voltage when they are wired 3 parallel sets of 2 in series for a 12 vdc system. I have included a connection diagram based on quick install guide that came with the BMV.RV Battery 6 x 6V with BMV-712.pdf thank you. George
