⚡ Power your ride with reliability that never quits!
The irhapsody Relay 120A is a heavy-duty 12V DC 4-pin SPST relay designed for continuous duty in demanding automotive environments. With a 120 amp max switching current, low coil power consumption (1.8W), and durable M6 stud terminals, it delivers reliable high-current performance across a wide temperature range (-30°C to +80°C). Perfect for split charging and other high-power vehicle applications, it outperforms typical relays by combining efficiency, durability, and precision.

Internal review of relay switch
If you are wondering exactly what this relay provides in terms of electrical design and implementation. Delighted to find solid copper internals, terrific dual brade, very flexible, stranded, woven ~8 AWG copper conductors from terminal #30 , a ~1/4 inch copper lug to activated contact. Terminal 87 of relay switch side provides a solid bar of copper rod 0.35 diameter with high temp contact on switch end. Plated high temp contacts are on both sides of high current switch as activated by relay. Relay operates well at 10 to 12 volts, with crisp aligned and swift magnetic force closure of switch. No bounce. Relay appears to be ok margin at up to maybe 220 volts as the base of the relay depends upon a piece of 0.07 inch thick plastic as isolation from 12 volt enamel coated solenoid wires AWG ~ #34 as connected to pins 85 and 86. Thermoplastic is higher temp, suitable wall strength, leg mount points may soften or melt at continuous duty of max current rating of device. For my application to deliver 200 A in a few milliseconds the device is well suited. YMMV

Installation and Quality
Relay works great. Easy to install. Makes my boating experience easier.

Works as intended
Works, it's a big strong relay that can handle at least 120amps (that's what I'm running)

worked good
excellent and fast...used this to power a audio amp.

Idk about 250 amps but it handles the load I have on it fine.
So far so good. Have it installed on my Cummins swap as a keyed power relay via a ground switch inside the cab. Have 4 fans direct wired and 2 radiator fans on a fan controller on it and it handles it no problem. Doesn’t even get hot.Not too sure about longevity but seems to be built well enough to handle a good amount of load. You wouldn’t think it would based on the size of the relay, (about 1.5x the size of a standard 30/40 amp relay) but it does it.

Awesome!
Worked great! No issues! Easy Install

Works with DC to DC Boost Converter.
I first tried the 40A small Relay which got too hot at 12V, 25A. Then I tried a SSR with heat sink which had unacceptable voltage drop. ... Finally with the irhapsody 250A Relay we are in business (I needed to add a flyback diode across pin 85 to 86). Excellent 👌🏽
