Quick Connects for Battery and Refrigerator/Freezer

The challenge with the type of DC cords the refrigerator/freezer came with is that they can jostle out of the socket when driving. Since I was going to connect these to external batteries I purchased cables that click together and its virtually impossible for them to disconnect on their own. The one for the battery can be found here and for the refrigerator/freezer can be found here These are known as Anderson connectors and its impossible to switch the polarity unless you hooked the cables up wrong on the battery. Red is positive and black is negative! I purchased enough of these that each battery has two sets which allows me to connect both units to one battery. Swapping cables out, while traveling, is a great way to make a mistake!
