These cables are made with very fine copper wire & insulated with synthetic rubber. It's more flexible than standard cable, especially in cold temperatures & easier to route in tight spaces. The best choice for battery interconnects (within the amperage range), controller to battery circuits and portable systems. It's called Welding Cable but works better than Battery Cable for Electric Vehicles. Very flexible & durable!
