4 AWG Black Battery Cable has an amperage capacity of 75 amps at a cable length of 14 feet. 4 gauge black battery cable is often used as a ground cable for small cars, RV trailers, golf carts, and small boats and trolling motors. It can also be used to connect multiple small batteries (lawn and tractor batteries) together in parallel to create higher voltage battery banks of 24, 36, and 48 volts. When used as a negative battery cable in a low voltage electrical system, remember that the total length of both the positive and negative cables have to be considered when selecting amperage capacity of the cable in your electrical system. Covered in a durable, high temperature resistant Black PVC insulation. Rated for low voltage and battery use up to 60 volts DC and 25 Volts AC. The internal copper stranded core is highly conductive maximizing current flow while still being highly flexible. Meets SAE J1127 specifications. Temperature rated from -50°C to 105°C (-58°F to 221°F). Made in the USA. RoHS Compliant

When using a 4 awg black cable for a ground cable, remember to take into account the total length of both the red positive cable and the length you need for your grounding cable. For example, if your black ground cable is 3 feet long, and your red cable is 6 feet in length, then your total system length is 9 ft. For 4 gauge battery cable, you system could comfortably handle 100 amps of continuous current with a voltage drop of less than 2%.
