Stinger SGP35 High Current 500-Amp Battery Relay & Isolator for Most Vehicles, Water-Resistant Design for Marine & Powersports, Handles up to 900A Surges, Dual Battery Isolator for Car Audio Systems

Use this with my 12K winch on my Jeep JLU. Wired to a factory auxiliary switch it offers an extra level of protection and eliminates a high amperage hot wire running though the engine compartment to the front bumper. I bought this brand based on positive reviews and was going to go cheap on an item that could cause a fire if it failed.

Selenoid interrupt for a winch I just installed on my truck. Works perfectly.

Nice to have

This thing as soon as you pick it up you know its built with quality. I haven't yet installed this in my vehicle but to make sure everything was working good I have test the relay and everything seems to be working good. Only issue I could see with installing this is that it may be a bit large to hide away in a smaller truck or car. I recommend everyone looking to purchase one just to purchase the 500 amp then you can cover all the bases without worrying if you are within the amp rating. I definitely would recommend getting this relay from searching for other ones this one seems the most high-quality.

Great Product

Bought this to wire my jeeps winch up to my voswitch panel so I can turn my winch on and off with my switch panel. Works great, went with the higher amperage one because winches under high load can pull 400+ amps. Plus I don’t like having a constant positive wire running through my jeep incase of wire rubbing or a fender bender causing a short. Easy to install and wire up if you have a basic knowledge of wiring. Will buy again

Very good

This replaced a relay in my transit bus that appears to have been replaced with a starter relay that was melting and in the process of having a rather unfavorable outcome. This relay hasn't gotten hot at all, and doesn't fail. My use case is all the aux power items (AC, lights, etc) on a 09 e450 transit bus

Excelente relay para conectar 2 pilas

Installed work perfectly 👌

good service and good product

I used this as a relay to power up my electric winch on my 4x4. Works great. Would recommend.

Excellent piece of equipment does the job just as it says on the tin?
