Good quality and included connections
I got them today. They look good and the internal wiring is good quality. I have to 525 Walbro Hellcat pumps that pull 15-25amps I've burned up a few relays because of the amperage. So hopefully these will be strong enough. Gonna up grade my wiring with the included copper eyelets and see how they hold up

I rhapsody relay, 4pin 120amp
I like the fact this high current relay has load terminal lugs and nuts. A more reliable high current connection. I used this relay along with an 80 amp circuit breaker to isolate battery power to a 1000 watt inverter in the event the inverter’s power switch were left on. This arrangement works well.

Great upgrade from car electric fans controls.
I have dual electric fans on my SBC and constantly having relay failures. These are perfect for high draw electric fans on your vehicle. Most kits come with cheap small relays that never last. This has been a fantastic purchase and will easily handle fans . Local auto parts wanted $20 for a cheap relay and came with no connectors. These have great connectors and no my fans are pulling more air since the orginals were restricting electric load to the fans. Upgrade your fans with a strong better made relay like this!

irhapsody 120amp 12v Continuous Duty Relay review
They look OK, a little light weight for 120A. I cannot take it apart to look and see how well the contacts are made. The pull-in Voltage is about 8 Vdc. I will use this in my small DIY LiFePO4 battery pack, the BMS will be driving this relay instead of relying on the MOSFET's of the BMS.

Great for electric fans
I have done several LS swaps for friends and family and have used this at least four or five times with zero problems for controlling the fans. Fans can pull up to 60 amps on startup sometimes a little bit more and with a 200 amp relay I don't think we'll ever see a problem. Earlier I had tried some 30/40 amp relays the generic ones and they did burn out after. Time but this one, all of them are still working without a problem
