With two batteries on your RV, to charge the battery bank using an external charger you will connect the positive side of the charger to the first battery's positive terminal and the negative side of the charger to the second battery's negative terminal. It doesn't matter if the batteries are connected to each other in series of parallel for this to be the correct connection.
Thanks god bless
You're very welcome, glad we could help!
How would you connect the charger if you are running dual RV batteries? That would be helpful to know. Thank you.
