Added a second battery to my fj cruiser and wanted to isolate the house battery when the engine was off so that my starting battery would be fresh to start, this is well made and works perfect.I added a switch inside the cab so that I can also shut off manually

A lot better than using those cheap relays they give you with compressor wiring kits

This wasn't exactly what I was looking for but it does the job and does it well. I was looking for an isolator and this doesn't really isolate the batteries until the ignition is off. I also installed this in a boat that doesn't have a true ignition source. ( push button start with a sealed switch that I couldn't break into ) I ended up running a small wire from the battery to a switch on the dash then to the isolator. I hit the switch to activate the relay.There is very little info anywhere on how this works so maybe I can help some future buyers. It is simply a relay swith. One large power wire from charging source to first battery, then another large wire from that same post to one of the top posts on the isolator/relay. Lastly you run a large power wire from the 2nd top post of the relay to the second battery. When you turn on your ignition it sends power to the unit which engages the relay completing the circuit between the two batteries, thus connecting them and simultaneously charging them. Turn ignition off and the relay disengages making it impossible for one battery to drain the other but also makes the second battery unable to be charged. ( why it needs to be a true ignition source )

Habe mir das Teil gekauft, weil ich beim anderen Auto beide Batterien so gekoppelt habe und die sich mit der Zeit gegenseitig kaputt gemacht haben. Hinterher ist man immer schlauer... :-)Aber das wird jetzt mit dem Trennrelais sicherlich nicht mehr passieren.Auch das anschließen ist super easy, wenn man weiß wo man sein Zündungsplus abgreifen muss, damit es schaltet.Alles in allem ein kleiner netter Helfer der die Batterien länger leben lässt und man nach einer gewissen Zeit Anlage an nicht mehr irgendwo steht und der Anlasser keinen Mucks mehr sagt. :-)

This solenoid is well built and up to the task. Performing well as a dual battery isolator charging system from my truck's battery to my camper's dual batteries. A+

Unless their claim is about the combined load of both batteries to be at 80 amps total, I wouldn't trust the ratings at all. I have a two 80 ah dual agm setup and the relay gets considerably warm during operation and my relay terminals literally melted, inspite of the connections being screwed tight.I'd advice against it, if you are even planning basic dual battery setup.

Es para si traes 2 baterÃas? Este aparato guarda carga en la baterÃa extra para que te de marcha sin que te quedes tirado sin pila pero lo único q no me gusto fue que iba a comprar otro y costo más del doble y mejor me espero gracias

Hay que hacer las conexiones correctas para puentear las dos baterÃas! es excelente a un precio asequible. Ya viene con un diagrama de como hacer las conexiones.
