Mine stays in the water year round. Makes for much less hassle when wanting to take it out. I have a group24 deep cycle battery and an automatic bilge pump. I charge the battery once every 2-4 weeks depending on usage.
I have a similar setup but took it a step further and bought a solar battery charger for it, now when I get a chance to slip off to the pond, which is 25 min away from the house, the boat is all charged up and ready to go. till some asshole steals the whole setup.
