I am adding a balancer to my battery system and want to clarify the wiring set up. I have a 24v 440ah configuration with 4 220ah gel cells. It is now wired with bussbars as recommended by Victron. Looking at the diagram in the balancer install sheet, it appears that the Common connection is simply wired into the midpoint circuit in the bank with the pos and neg terminals connected at the bussbars. Am I interpreting it correctly?
If this is the correct wiring set up, what is the actual balancing provided by the unit? Does it balance across the 2 series connected 24v cells only?
