4 AWG Copper Battery Cable Power Wire Car, Marine, Inverter, RV, Solar

Red or Black with Ends, you choose the length and ends


Your choose your length, color and cable ends from the options above near the purchase buttons. The copper ring terminal lug cable end choices are 5/16 or 3/8 which are professionally crimped onto the red or black copper battery using the UL approved crimping tool as specified by the manufacturer.  We then seal the connection point with adhesive heat shrink tubing in the color to match the cable. The heat shrink has a melt-able glue lining to help seal your cable from air and moisture. The copper lugs feature a tin plating which is resistant to corrosion you'll see on bare copper ring terminals.

If you need something special with regard to the length or lugs outside the available options please send us a message and we may be able to help you out.  


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. 



  • 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 Uses


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:

  • 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
  • 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

  • ...and many other uses
Final pointers on lug sizing....most threaded stud batteries will have either a 5/16 or 3/8 inch stud. Most of the time the negative will be 5/16 so if the positive is the same size it is also 5/16, but if your battery stud is larger on the positive it will most likely be a 3/8.  There are exceptions to the rule so please contact the manufacturer or measure. You can search online for bolt sizing tables which will help.
