Review on 🔌 High Performance HYCLAT Red 2-4 Gauge Battery Quick Connect/Disconnect Wire Harness (4 Pack): Ideal for Motors, Recovery Winches & Trailers - 175 A Plug Connector by Michael Walker

I had an old substation build "Anderson tool" and found it did a great job of crimping ferrules that were thick enough in material to hold their shape during and after to keep crimping. Definitely needs a serious crimping tool to get the job done. I can't say anything about the electrical properties yet. The parts fit well. The label holder on the lid is too short to be useful. This is cheap wire. I wish they had added at least two more inches to make it useful.
