In this video, my good friend Eddie from Mobile Homestead Solar Services was kind enough to give us a few tips on how to make up your own custom heavy gauge RV battery or Inverter cables.
I caught him while he was installing a battery bank consisting of 6 new Battle Born lithium batteries. They will be powering a large wattage inverter, so thick gauge 4/0 cabling is required to minimize power losses in the wiring.
We watch as he applies a Noalox anti-corrosion paste to improve the connection/crimp conductivity, crimps on 4/0 cable lugs then adds protective heat shrink tubing. Along the way, he provides several expert tips.
