Review on 🔋 SHIERLENG 4 AWG Gauge Red + Black Pure Copper Battery Cables - Ideal for Solar, RV, Car, Boat, and More! by Knate Scarpelli

At first they looked pretty good. Then, within a few hours, I realized that I was no longer being grounded. Looking down and the wire had just slipped out of the crimped end. The positive wire did the same an hour after the floor was repaired. Plan to re-crimp or re-solder those poorly made wires.
