I used them to hook up a portable winch. These were the only connectors I could find that handled 450 amps. I read a few reviews that said they couldn't get them to lock/seal. 2 things: There is DEF. this is the male and female end. PAY ATTENTION. I didn't get it and had to redo the positive cable. 2. Some reviews said they can't install isolators. I softened them with a heat gun and they put them on (and took them off again) immediately as these were the only negative reviews I read I gave them 5 stars. They are as described or better. In fact, I was stunned when I saw how big they are. lol Got a replacement as the packaging was destroyed and the insulator + and plugs were missing. I received my replacement with no problems and in a timely manner.
