BERLAT SAE Connector SAE to SAE Polarity Reverse Quick Disconnect Cable Plug Adapter for Solar Panel Battery Power Charger - 5Pack

I needed a way to adapt my wiring project so that I wouldnt confuse my positive and negative wire paths. This was the easiest way to adapt and keep the red and black wires either positive (red) or negative (black). Im not done with my wiring project, but I cant wait to finish and give it a test run...

maintains batteries via solar

was just what i needed for my harbor freight solar kit to work with my new trailers FERRON external solar port.

Simple solution to retain proper wire polarity

If you order the long jumper cable with the plugs for quick disconnect got to have this adapter or it will blow your battery fuse

Needed these for a number of power equipment that use 12v power. Very useful.
