Premium Conductor: Oxygen-free pure copper with high-strand count (1070/0.2mm) to ensure maximum conductivity and ultra-low resistance, effectively reducing power loss and heat generation, improving electrical equipment efficiency; 3/8-inch ring terminals are made of solid copper and tin-plated for enhanced corrosion and oxidation resistance, maintaining stable performance in harsh environments; terminals are firmly crimped for reliable connections without slippage; true 2AWG specification with 12.5mm outer diameter, up to 150A instantaneous current/600V rated voltage, ideal for high-load power scenarios; UL certified, VW-1 flame-resistant rating for added safety assurance

High-Strength Flexible Jacket: The black and red wires use premium flexible PVC insulation material, offering excellent wear resistance, waterproofing, moisture resistance, flame-retardant, and heat insulation properties; the negative wire (black) includes an extra PE isolation layer for higher insulation strength; heat-shrink tubing seals the ends for additional moisture and oxidation protection; temperature range from -35℃ to 105℃, maintaining flexibility and safety in both extreme cold and high-heat environments; clearly color-coded jacket (red for positive, black for negative) for quick identification and installation

Easy Installation: Available in multiple lengths (1-6 feet) to flexibly meet different installation distances and connection requirements; both ends equipped with firmly crimped ring terminals, ready to install out of the box with no extra processing needed; flexible design allows easy routing, even in confined spaces

Multi-Purpose Application: Widely applicable for cars, trucks, RVs, boats, motorcycles, golf carts, trailers, lawn equipment, solar systems, inverters, power tools, and more; can serve as battery cables, grounding cables, or inverter-to-battery connection cables, meeting the demands of daily, industrial, and outdoor power supply; suitable for car audio upgrades, RV off-grid systems, marine energy storage, and solar grid-tied/off-grid systems
