I have a BMV-712 today in my boat, reading the voltage for both the house bank and the starter battery. (These batteries are separated with a Cyrix-Li-ct.)
Since I have Lynx Distributors, I am looking at replacing the BMV with a Lynx Shunt, so that I can get power to the Lynx Distributors and monitor them through my Cerbo GX.
However, I do not see that the Lynx Shunt can read the voltage on both the house bank and the starter batteries, and I guess it is not possible to have the Cerbo GX to read the voltage directly from the starter battery.
Is the only solution to keep the BMV in addition to the Lynx Shunt, or can I provide the voltage for the starter battery to the Cerbo in another way?
If I have to keep the BMV, do I have to use the aux input to read the voltage on the starter battery, or can I use the "main" reading on the BMV for the starter battery? (Will this confuse the Cerbo?)
