I have a Multiplus-II and two 100 ah lithium batteries (plus smartshunt, lynx, etc.). The system has a battery monitor similar to the Victron BMV-700 (I think it is a cheaper knockoff, but functions the same). I want to know if I can add a second monitor, as a “repeater,” so that I can monitor the battery charging while driving (this is in an RV). Is this simply a matter of putting a “splitter” in the base of the first monitor and running a chord to the second monitor, or is there a lot of details to figure out. I want to be able to monitor the state of my batteries while driving, checking on the amount of solar watts coming in, and supplementing with a DC/DC charger when necessary.
Since you have a smartshunt, you can use VictronConnect on your phone to monitor the SOC of the batteries. Maybe not while driving, but theres AndroidAuto compatibility in beta now…
As for the monitor, its not quite easy to help if we dont know the type that is used. Even if it looks like a cloned BMV it could work completely different. Besides that, again, you got a smartshunt, so why bother with another batterymonitor
Yes, you can add a second battery monitor to your system to track a second battery bank individually, or as a repeater, though it requires separate wiring for the new shunt. This is useful for monitoring starting versus house batteries or ensuring balanced charging in complex setups.
