I do this often to keep my 4 six volt batteries in good shape.
First of all, set your charger on the 12 volt charging option (most chargers have six and twelve volt options or if digital will sense the proper voltage setting).
Next connect the positive charger cable to the positive battery terminal which is connected to the 300 amp fuse leading to the inverter. This is the positive cable that enters the interior of the motorhome.
Then connect the negative charger cable to the negative terminal in the battery bank which is connected to the cable that enters the coach and establishes the ground connection for the battery bank.
Make sure you use a good 3 stage charger for the operation and realize that it may take up to 2 days to fully charge your battery bank.
