Miady5-Pack 12" 10 Gauge 2 Pin Quick Disconnect Audiopipe Polarized Wire Harness, Heavy Duty SAE Connector Bullet Lead Cable, SAE Power Automotive Extension Cable for Motorcycle, Car, Tractor.

I bought these to hook some small solar panels to some batteries on our boat to keep the batteries topped off. I wanted something easy to disconnect that kept the polarity right so that I could not accidentally hook it up backwards. These seem to be pretty high quality and work as I would expect. Time will tell how well they will hold up in the elements and sun, but so far, I like them.

they work..

They work well, I found the gauge to be a little thick. But I managed to set up several trickle chargers for winter

These "extensions" daisy chain and change the plug polarity while maintaining the electrical ploarity. For my purpose, this was exactly what I needed, cutting the wires and using the straight and reversed plugs as needed. The plug plastic is high quality and slightly flexible, seating fully and securely with strong finger force, and while not water tight, snug and resilient enough to be weather resistant and semipermanent.The 10 gauge wire is a fine, multi-stranded, bright copper, and covered with tough, serviceable plastic. These "harnesses" are high quality in every respect and indeed do merit the description of "Heavy Duty." The prongs and sockets are sturdy and nicely plated, embedded solidly in ergonomically designed endcaps, and as one would expect from a first rate harness, exhibit no measureable resistance with a Fluke VOM.I have cut and soldered my harnesses to fit my custom use and they have proven to be flawless in materials, design and construction. I would buy these again without hesitation.

You won’t have a fault in this area with these connections.
