We recommend using at least a 14 gauge wire with your 12 V battery bank. If your 13 A electric cables are 14 gauge or bigger you should not have any issues. If you do not have the correct size, you can use the Deka Jacketed 4-Wire - 14 Gauge - Per Foot, part # DW04923-1. This is a 14 gauge wire we sell by the foot.

I have included a product description link and a video installation of this wiring being installed below.
