4 AWG 4 Gauge Positive Battery Cable Custom MadeCopper battery cable conductor and copper connectors!This custom made top post positive battery cable comes with a top quality copper top post positive connector which is tin plated to resist corrosion, double crimped onto the cable and then you choose the length of the cable as well as your choice of an optional ring terminal available in various sizes, on the opposite end.You choose your length, which is measured from hole center of one connector to the hole center of the connector on the other end. The options for length and connectors are located near purchase buttons. The optional lug choices for the opposite end are 5/16 (fits 5/16 bolt & M8) or 3/8 (fits 3/8 bolt & M10) with adhesive heat shrink tubing applied matching the wire color. The heat shrink has a meltable glue lining to help seal your cable from air and moisture. The copper connectors feature a tin electro-plating which is resistant to the types of corrosion you’ll typically see on bare copper terminals.If you need something special with regard to the length or lugs or heat shrink color which are outside the available options please send us a message and we may be able to help you out. ABOUT THE WIRE USED:This 4 AWG Gauge extreme battery cable is specially designed to meet the demands of various environments while staying extremely flexible. Full AWG sized copper conductor made from 99.9% pure annealed electrolytic copper, will you get maximum power. The insulation and jacket compounds are specially formulated to stay flexible even in cold weather and carry a -49C to 105C temperature rating. The jacket is resistant to chemicals, water, abrasions, oil, sunlight and has a color coded dual extrusion jacket with a white inner insulation which would show any damage to the outer cable more clearly. This cable is rated up to 600 Volts and is suitable for use in automotive applications, solar battery bank wiring, power inverter battery cables, marine battery cables and many other applications calling for a durable yet flexible battery cable. The battery cables meet the requirements of SAE J1127 and J378 making them ABYC and US Coast Guard approved for boat and marine use.BENEFITS OVER WELDING CABLE: Full AWG Size Copper Conductor TPE Jacket is Oil Resistant where EPDM on many welding cables is a poor insulator against oil SAE Rated for Automotive and Marine UsesBENEFITS OVER CCA POWER WIRE: Our cable is Copper…REAL COPPER but watch out for other “CCA Cable” as CCA Means Copper Clad Aluminum so you’d be using Aluminum which is a poor conductor compared to this pure copper cable! You have to use larger sizes of aluminum CCA cable, approximately 2 sizes larger to get close to the same power delivery as real copper cable! If you care about maximum power use our cable!The jacket on the cable reads as follows:BATTERYCABLESUSA.COM 4 AWG MARINE SAE J378/J1127 600V (-49C to 105C) MADE IN USABenefits: ABYC and USCG Approved for use on boats SAE J1127 Approved SAE J378 Approved TPE Jacket is Very Resistant to Oil, Water, Acid, Gas, Tears and Abrasions The Jacket Insulation Meets UL FT1 Flame Resistance Rating Annealed Electrolytic Copper with Class K (Type III) Rope Lay for flexibility FULL AWG Copper Content MADE IN THE USASpecifications: Conductor Size: 4 AWG Stranding: 420 strands of copper (30 AWG ea strand, rope lay Class K) Outside Diameter of stranding: 0.252 inches (nominal) Outside Diameter of finished cable: 0.440 inches (nominal) Amps: Rated to handle 160 amps continuous outside of engine space (136 amps continuous inside engine space) Weight: 0.214 lbs per foot Suitable Uses: Automotive Battery Cables Marine / Boat Battery Cables Solar Battery Bank Array Forklift Charging Cables Power Inverter Cables Welding Cable Leads Amplifier Wiring …and many other uses
