This 4 Gauge Copper Battery Cable features a high-strand pure copper conductor and flexible PVC insulation, terminated with pre-crimped copper lugs at both ends. Factory-crimped connections eliminate the need for on-site crimping tools and ensure consistent, low-resistance termination. Designed for 12V/24V/48V DC power systems, it delivers stable current transfer in automotive, marine, solar, and industrial battery bank applications.
-
Ready-to-Install Termination:Pre-crimped lugs save 30+ minutes per connection compared to field crimping, with factory-controlled crimp height for uniform pull-out strength and minimal resistance .
-
Pure Copper Conductor:Stranded oxygen-free copper provides higher conductivity and lower voltage drop than CCA alternatives, maintaining stable performance under high-current charging and inverter loads .
-
Flexible PVC Jacket:Resistant to abrasion, moisture, and common automotive fluids; remains pliable in temperatures from -20°C to 105°C for easy routing in tight engine bays and battery compartments .

About This Item
【Heavy-Duty Power Transmission】- These 4 AWG battery cables are designed to handle high current loads, making them ideal for demanding applications. They are constructed with 4 AWG pure copper wire, providing excellent conductivity and efficient power transfer for your inverter, battery, or other electrical components.
【Secure and Reliable Connections】- The battery cables feature 3/8-inch copper lugs on both ends, ensuring secure and reliable connections to your battery terminals and inverter. These lugs are tin-plated for corrosion resistance, providing long-lasting performance and reducing the risk of electrical issues.
【Protective Heat Shrink Tubing】- Each cable end is professionally sealed with heat shrink tubing, providing insulation and protection against abrasion and moisture. This added layer of protection enhances the durability of the cables and helps prevent short circuits, ensuring safe and reliable operation.
【Optimal Length for Versatility】- These battery cables are 4 feet in length, offering a balance of flexibility and efficiency for various installations. This length is suitable for connecting batteries and inverters in a variety of vehicles and applications, including automotive, solar, marine, RV, and motorcycle systems.
【Clear Color-Coding for Easy Identification】- The battery cables are color-coded in red and black for easy identification of positive and negative terminals. This clear color-coding helps to prevent accidental misconnections, ensuring safe and proper installation of your electrical system.
Suitable for battery-to-inverter connections in RVs and campervans, starting and grounding circuits in boats and golf carts, solar battery bank wiring in off-grid systems, and heavy-duty automotive audio power runs. The pre-crimped lug design is particularly effective for installers who need consistent termination quality without carrying hydraulic crimping tools to each job site.
FAQ
Q: Can I order custom cable lengths?
A: Yes. Standard lengths are 1ft, 2ft, 3ft, and 5ft. Custom lengths from 6 inches to 20 feet are available with MOQ 500 pcs per length.
Q: Are the lugs tinned?
A: Standard lugs are bare copper. Tin-plated lugs are available upon request for enhanced corrosion resistance in marine environments.
Q: What stud sizes can you supply?
A: 5/16" (M8) and 3/8" (M10) are standard. Other sizes including M6 and 1/2" can be quoted.
