Two of these seven watt solar panels can be hooked up to a single battery. To be safe a charge controller should be used to prevent over charging.

Yes, but what would work better is two batteries, hooked positive to positive, negative to negative, brought to a full charge, and THEN put a panel on each battery (the same as two on one battery).
The reason I suggest two batteries, is the deeper a battery is discharged, the more current it takes to bring it back up to a full charge. Adding a second battery will buffer the drain you put on your setup, allowing for a faster full recharge.
