My boat has the following set up:
1-12 volt battery for electronics,
1- 12 volt battery for the house,
2- starting batteries and
1- bow thruster battery.
House and electronic batteries are on a on/off/combined switch.
I would like to add battery monitors to the House, electronic and bow thruster batteries.
I know the thruster battery will needs its own monitor.
The question is can I connect both negatives on the House and electronic batteries to the Shunt inlet side and monitor both batteries. Or will I need another monitor.?
