I am reading, about shunt and ohm's law, then it reminds me some very old memories from school
I was reading on an other forum that it is good to take some safety precautions with a shunt, because it can become very hot.
Which ratio is good to respect ?
To measure 20A install 100A shunt ?
More or less ?
What about something cheap like that : https://fr.aliexpress.com/item/Good-perf...Title=true
I'm just piggy backing my ina219 on top of the battery monitor shunt which from memory is something like 500A, 50mV. Your link looks OK though might be a good idea to have any really big loads like a bow thruster direct to the batteries.
