These battery terminal connectors are designed to provide a secure connection between battery cables and terminals, preventing power loss and voltage drops. These copper lugs are safe and reliable to use with heat shrink tubing, perfect for marine, automotive, distribution boxes, golf carts, solar panels, boats, home applications, vehicles, motorcycles, DIY wiring and other outdoor applications.
This Copper Cable Lug is made of copper and is installed using crimp method. It has a wiring specification of 4/0 Awg, with a terminal hole diameter of 5/16 inches and a head inner diameter of 14.2mm/0.56 inch. The total size is 39x26x8.5mm/1.54x1.02x0.33 inch and comes with 8 wire lugs including 8 3:1 heat shrink tubes (4 black + 4 red). The 3:1 heat shrink tubing size is 19.0mmx55mm/0.75x2.17 inch
90-degree bent copper lugs are made of pure copper to resist high temperatures and corrosion, ensuring minimal resistance and maximum power transfer. The 90° design fits snugly on battery posts and bolts, and can be connected by crimping and welding, ensuring electrical components, batteries, and cables are safe. 3:1 adhesive heat shrink tubing seals the connection and has excellent insulation properties, protecting the connection from heat, dust, moisture, and corrosion.
1.Crimp Tightly: Use a crimping tool to compress the lug barrel securely onto the wire.2.Seal with Tubing: Slide the heat shrink tube over the connection and apply heat (e.g., heat gun) until fully sealed.
Ensure the lugs AWG rating matches your wire gauge for a safe, snug fit.
