Fusion Solder Lugs and Battery Terminal Connectors

Fusion Connectors are crimp-less terminals and lugs that come with flux and solder pre-loaded into the barrel of the connectors. This method is the strongest for bonding the cable to the connector making a long lasting and dependable connection. Solder connectors prevent dirt, debris, and moisture developing within the connector barrel making them the longest lasting connection method for cable and connectors.
