Solder slugs for 4 gauge battery lugs. Solder slugs are convenient pre-measured amounts of solder. They are inserted into the battery lug; and placed in a vice. Then the battery lug is heated and battery cable gently pushed downwards for the perfect connection. Make sure to check if your need to install a piece of heat shrink tubing around the cable; before soldering; to allow you making a weatherproof seal between the battery cable and battery lug afterwards.
