Comment brancher le chargeur (2 Banks) a deux batteries en série pour que le smart shunt puisse avoir une lecture en toute sécurité
Hello, welcome to the forum.
Can you make a drawing? Its not clear to me how the negative wire is connected in your situation.
If you have only one negative wire on the output of the batteries to the bus bar (batteries in series) then you can connect the SmartShunt there.
