Battery Cable, Inverter Cable, 4AWG, 30 inch, Black/Red, 18.0030-BR, PVC

Use these cables between a battery bank and inverter, fuse or power center. They have flexible stranded UL Listed copper wire and 3/8 in. diameter lugs. Make sure to check your battery posts to ensure they can accept this type of connection. Lug barrels are covered with glue-filled heat-shrink tubing. To select the proper length of cable, put the battery bank in place and measure the distance between the battery terminals you need to connect. Choose a length that is slightly longer than the measured value. Avoid selecting an interconnect cable that is too long, since this may cause you to bend the cable significantly in order to get in in place. Tight bends can cause wear or cracks in the insulation or damage the conductors and should be avoided. If necessary to bend the cable, use only slight bends.
