Review on Hamolar 2 Pack 12V 40/30 Amp Car Relay DC 5 Pin SPDT and Harness - Heavy Duty 12 AWG Copper Wires Relays Kit Bosch Style for Automotive Truck Van Motorcycle Boat - High Performance and Reliable by Curtis Castillo

My project is not finished yet so I tested them on the workbench. Both work as they should with advertised lead sensors. I activated one of these for over 2 hours and it felt a little warm so it looks like they really have 100% duty cycle. The stud mount is a bit odd as it attaches to the relay instead of the socket. The relays appear to be sealed so may actually be watertight, but there isn't even a cover for the sockets so nothing there is protected from a short circuit. Good price, recommended.
