cranking circuit you want a shunt that can handle that with ease. If it is a bow thruster, electric
etc. it too needs to handle those with ease... Most reputable
Ah counter manufacturers ship 500A rated shunts and most often 50mV.
To me one of the best values
, for what you get, is the Victron BMV-700....
Once again thanks!
As I understand you 500amps is the way to go. That leaves room for the starter motor
, running cooler and a future anchor windlass
all to be on and not mess things up.
I am going to shunt the ground leg as that is IMHO safer.
