Package includes: 1 piece red 16 mm² battery inverter cables + 1 piece black 16 mm² battery inverter cables. Heavy Duty Safe Cables: Tinned copper wire has good electrical conductivity, thermal conductivity, stability, tinned copper can increase heat dissipation, improve electrical conductivity and improve wire performance. Tinned copper connection: tinned copper has good stability, wear resistance, corrosion resistance, which improves the oxidation resistance of copper and better retains its conductivity. PVC Insulated Sheath: Flexible PVC insulation of battery cables is resistant to wear, waterproof and moisture resistant, flame retardant and heat-insulating and resistant to the rigors of an automotive or marine environment. Durable brass battery connector, which has excellent conductivity and flexibility to reduce voltage distortion and power losses. Voltage: 12V or 24V, thread: M8. Package Contents: 1×Positive cable with battery connections (red) 1×Negative cable with battery connections (black) Features: Voltage: 12V or 24V Maximum current: 100A Battery terminals Threaded connectors: M8 Cable length: 20.5 cm Operating temperature range: -15°C to +105°C Cable material: tinned copper wire and PVC insulated sheath Clamp material: tinned copper clamp Wide range of applications: is used for power applications in cars, camper trailers, golf carts and small vessels, also ideal for small solar cable applications. Safety instruction: when installing battery cables: First install the positive (red) cable, then the negative (black) cable. When removing battery cables: first remove the minus cable (black) before wearing the plus cable (red). Wear goggles while working.
