Battery Monitor shunt installation on Roadtrek RS
The whole thing with the shunt placement is that all the current from both batteries has to go through the shunt which is placed in a common negative battery cable. With the batteries underneath and on opposite sides, getting a common ground and trying to get the shunt inside the van where it will stay clean can be quite an exercise.
Does a Smart Shunt or battery monitor become unnecessary for …
The BMS communicates with the Cerbo GX and reports the internal cell status, SoC, temperature and requests the optimal charging voltage/current from the Cerbo GX. Does this imply that the Smart Shunt (or BMV-712) becomes unnecessary? IMHO, the BMS should be able to report all the values (and more) which the Smart Shunt does report.

Making Sense of Shunt Sensors: All Your Questions Answered
Almost all manufacturers constrain the maximum continuous shunt current to be 2/3 of the shunt''s current rating, called its operating current. This means the maximum continuous current a 100A shunt can tolerate is 67A! Therefore, if the maximum, continuous current is 100A, a shunt with a current rating of 150A is required.
