You could easily feed two 6 volt golf cart batteries in series with an 85 watt module. I would buy a quality charge controller to turn off the panels and prevent overcharge.

My first batteries were small gel cells. They only lasted a few months. Some large UPS's have gel cells that are larger than automotive batteries. They last longer but also will fry from equalization.
