I am in the process of rewiring my sailboat power distribution. I have (2) FLA batteries, house and starting. The battery negatives are tied together. The house and engine loads will each have a 1/2/Both/Off switch. I’d like to monitor the voltage and current (in and out) on each battery. I don’t really care too much about SOC (or should I ?). If I put a SmartShunt on each battery, is there a single display device that will give me the voltages and currents I’m looking for? Will the phone app do that as well?
If you want to monitor the starter and house battery currents separately then you need 2 shunts. You can give them different names and monitor them both from VictronConnect phone app at the same time.

Would (2) BMV-712 Smart Battery Monitors accomplish what I want? I like the idea of having a permanent display. They come with 500A shunts, but they’re described as quick connect shunts.
As I understand this (barely),
I can use (2) Smart shunts @$71 each + (1) Cerbo-GX @$248 each + (1) GX-Touch @$220 = $610 total,
or (2) BMV-712 @$159 each = $318.
What the advantages and/or disadvantages of each of these solutions?
Yes you could use 2 x BMV 712 and have physical displays.
Yes, you could add a Cerbo GX and touch screen to the SmartShunts. You would also need 2 x VE Direct cables between the SmartShuntsand the Cerbo. The advantage with the Cerbo really comes with larger systems where you have other Victron equipment such as inverters, chargers, solar etc. Another advantage is if the Cerbo is connected to a router you can store info on VRM (the Victron cloud service), view your installation remotely.
