Helpful Expert Reply:
With two batteries on your RV, to charge the battery bank using an external charger like the 2.5-Watt Solar Battery Charger # PTW2997 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.
With this charger you will either have two 12V batteries in parallel or two 6V batteries in series to get your 12V output.
