Review on 💡 Gray Wire Connector 2 Pack: ORION MOTOR TECH 50A Wire Harness Plug Kit for 6-12 Gauge Cables, Quick Connect Disconnect Set for Car Bike ATV Winches Lifts Motors & More, 12V-36V Battery Compatibility (Set of 2) by Terrance Duncan

Reliable and offers a clean, fast connection. I moved my battery to the front of my small boat for better weight distribution and to switch between an electric trolling motor and an electric start gas motor. I installed a battery extension at the back of the boat, one at the stern. The cable from each of my motors has one of these at the end. With the gas engine connected, I start the engine and drive to the fishing spot. Quick toggle and I troll for a few hours. Another switch and I'm off to a new place to troll. However, I had to buy a battery with a duel function. Switching is easy. However, the absence of ANY assembly instructions is unforgivable. I decided to solder the connections instead of relying on crimping.
