If you will be leaving the boat in the water then having a battery back up would be recommended. Or, at the very least, store a spare battery that is not connected to anything in case it is needed. If the boat will not be stored in the water then leaving the pump connected to the regular trailer battery will be fine.

Using a charger like # 329-GENIUS5 is the best way to charge and maintain a 12 volt battery. I own one of these chargers and it works great; much better than a trickle charger since it will not overcharge a battery.
