I have a cerbo gx happily connected to a 48v house bank on a boat.
The 48V BMS is connected directly to the cerbo via a type A cable, and the battery charged via 48V 100/20 MPPTs.
I have a 12V starter battery.
I have an old 702 shunt that I’d like to measure the 12v starter battery (easy - have done) and have the voltage and current available, either on the cerbo itself or at least on signalk.
I have a ve.direct to usb cable to connect the old shunt to the cerbo.
Can the cerbo be configured to get what I want? If so, how?
