Review on ⚡️ Powerful 300A Continuous Duty Solenoid Relay for Golf Carts, Winch, Marine - Nickel-Plated - 12VDC by Joshua Albright

Revainrating 1 out of 5

Not suitable for 100% continuous operation

Before installation, connect the coil/actuator contacts to 12V (no load) for about an hour to check the coil strength and temperature. Within 30 minutes the magnet was very hot (almost melted wire), indicating high wear, poor quality and most importantly safety. A true 24/7 100% duty cycle unit can be warm but shouldn't get that hot. I bought a couple of these to look for a 24/7/100% duty cycle solenoid to charge auxiliary batteries when the ignition is on, but they don't work.

Pros
  • Handy part
Cons
  • Large and bulky
