Lucky Seven Max 300A Continuous Duty Solenoid Relay Nickel-Plating For Winch, Golf Carts, Marine In Rush 12VDC E-Z-GO Gas Marathon models with 2 or 4-Cycle Engines

The Max 300A Continuous Duty Solenoid Relay by Lucky Seven has been a solid addition to my Humvee setup. When you’re dealing with higher current applications, reliability isn’t optional—and this unit has delivered exactly that. From the start, it’s been consistent and dependable. It engages cleanly every time with no hesitation, which is critical when you’re running accessories that require steady, reliable switching. No intermittent issues, no weak engagement—just solid performance. Build quality is what you’d expect from a heavy-duty solenoid. The nickel-plated terminals are a nice touch, helping with corrosion resistance, especially in environments where moisture or exposure can be a factor. It feels robust and well constructed, not like a cheap component you’ll be replacing anytime soon. Handling high current loads hasn’t been an issue at all. It stays stable under continuous use, and there’s no sign of overheating or degradation in performance. Installation was straightforward, and once in place, it’s been a true set-it-and-forget-it component in the system. If you need a reliable, high-current solenoid for a vehicle, winch setup, or similar application, this one gets the job done without drama. Strong, durable, and consistent—exactly what you want. Highly recommended.

Worked perfectly no issues

Worked exactly as it should,no problem with it

Spend the extra money and buy decent ones, the back jam nuts were loose , when tightening the outer main power nut the unit just turns on its own, I bought two and the both do it, poor quality.

it works as intended but needs a diode between the switch poles so it doesn't feed a little power when turned off.
