November 20, 20241 yr I'm driving myself crazy looking, relooking, thinking and rethinking how, or if, to connect the second Aux connector from the BMV-712 to my battery bank. I have read all the manuals but none mimic my system, so I'm battling to work out which +ves to connect to. Sorry for the crude image but this is my set up. 8 x 12v 100ah batteries in series / parallel giving 2 x 48v 200ah. The pink lines are the positive and negative outputs to busbars. The black rectangle at the top is the shunt placed on the negative output and connected to the BMV-712. The shunt has B1 and B2 terminals. Where do these connect? If I understand it correctly, B1 is connected to the +ve of same battery the -ve connects to the shunt. Shown by the orange line. Is this correct? If not, which positive should this be connected to? And then where would the midpoint be to connect B2? Or do I need B2 connected? Thank you! Edited November 20, 20241 yr by ClintonDBN
