OK, I hooked up my brand new right out of the box BMS 12/200 to my brand new right out of the boxes 150AH Victron smart lithium batteries, wired exactly as depicted and wired in the sequence indicated and I am only getting 12.3 volts on the AB side and only 12.7 volts on the LB side. No current to speak of, nothing runs. I took every thing apart thinking somehow the micro processor needed to be reset somehow and again hooked everything back up and no joy. Before I send this thing back and demand another I need to trouble shoot it and there is squat on that in the literature. Just this Victron community thing where a question may or may not be answered. I have a few unanswered questions out there still.
