You should have two switches - one will run them on 12 volts and the other on 110 volts.
Holding tank heating pads that are not both 12 volt and 120 volt. There are made in 12 volt and 120 volt configurations. I doubt a manufacturer would install both!
Because of the high wattage demand of 12 volt models, they would very quickly deplete any batteries. Using 12 volt models while plugged into shore power puts a similar demand on the converter to power those 12 volts; therefore, the 120 volt models are the most practical.
