Kicker's Warhorse BT4S battery terminal lets you safely and securely connect up to four cables to a single battery post. The BT4S fits on either the positive or negative pole of your battery — red and black markers are included to help you keep things straight. A side post adapter comes with this connector so it'll fit onto almost any battery. Versa Gauge™ output sockets can accommodate different-sized wires for different power applications.
