Hi all, I am looking at installing a battery monitor for my two deep-cycle house batteries and my two starting bank batteries. My question is this, should I get a monitor that reads both banks? I know that normally the starting bank is topped off as soon as the motor starts and runs for a bit. And I have read here that some feel that you don't really have to monitor the starting bank for that reason. There is a bit of difference in price between the single bank and dual bank monitors. I am looking at the Victron BMV 602 or 600.
