SAE Battery Charging Cable 10AWG SAE to O Ring Terminal Connectors Harness Wire, 2-Pin Quick Disconnect SAE Extension Wire for Solar Panel Motorcycle Etc with 1 SAE Polarity Reverse Connector

Lead wires were shorter than I anticipated.

I think it’s a good value. I needed a larger gauge wire for my battery on my bike and this is great. Wish it was longer than the 12 inches but it works great

this makes it really easy to have a connection at the ready on your battery. I have a portable solar system that I hook up to the secondary battery on the truck and use it for keeping lights and other things charged when camping offgrid for days. this lets me simply plug the solar in rather than using clamps . Includes a polarity switch if needed

This cable has the wrong polarity at the connector. The red wire should be positive and the black wire should be negative, but it is reversed. It will work if you put the adapter in line, but then the cap doesn't fit and, more importantly, you may forget and connect something without the adapter resulting in damage.

If you need an extra set of battery wires, this is a thoughtful set. O-ring terminals provide the greatest contact. Consider using some dielectric grease. Polarity is maintained by the shape of the plug, and you need a coupler, one is provided. 10 gauge wire would suggest it can handle the current from the tender.
