I have a bank of two 12 v batteries connected in parallel. Apart from the two connector cables between the batteries, there are connections to loads or chargers on each the 2 positive and 2 negative battery terminals. Judging by the different cable diameters, these connections are in pairs and diagonal across the battery bank, so all OK.
Now, to install the BM shunt, and for the Battery Monitor to function, I need to place all the negative connections on the single “loads and chargers” terminal of the BM shunt and to connect the battery bank negative to the other terminal of the BM shunt.
Question: having moved all negative connections to a single point, should I also transfer all the positive connections to the single battery bank positive, so that all loads or chargers connections are once again diagonal on the battery bank, and the equilibrium of the two batteries is maintained?
Thanks for your help.
Yes, move them to the same point. Even the low resistance of paralleling wires can have an effect on battery balance. Do it properly…
