Marinco 12VTR Battery Direct Connect Multi Connection Battery Terminals - Heavy Duty Marine & RV Battery Terminals for Boats, Trucks, ATVs - Secure Power Connection for 12V Systems

Takes what was 5 connections to each battery pole and turns them into 2 flat, easy-to-handle connections. This makes it much easier to disconnect and reconnect in order to save battery power from idle draw as well as making a solid connection that reduces problems from vibration. The unit is substantial, not lightweight and cheap. Each connector has four individual plug connectors that are easy to remove and crimp with cramping tool or needlenose pliers. (Don't forget dielectric grease... Not required but always good for plug connections.)
