Worked great on my 2004 Damon Challenger motorhome

Unfortunately there's not a lot to say about a relay like this. It seems well constructed and it operates as intended. Where this shines is not in it's appearance or function, but in its price point. These things can get really expensive for some reason, but if you cut open a couple burned out ones like I have, you'll see that there's not much to them. This one is nice and heavy which tells me they didn't cheap out, and the price is very reasonable. I'm happy with it so far, but I will update this review if it dies on me.

Good price, works as expected. What more could you want?

We live and travel 100% of the time on a 52' boat and anchor out 99.99% of the time. We have three freezers and a desalinator on board for off-shore cruising to/from the NorthEast Coast, Bahamas, Gulf Coast, and most of the Rivers along the way. These items all require a lot of energy so we need to generate our own electricity with the combination of Solar and Diesel Generator that top up an 1800AH Lithium House Battery Bank. Whenever charging the House Battery Bank we also charge our Start Batteries with this type of latching relay and then disconnect the Start Batteries from the circuit when not charging.This relay requires a minimum of 3A at 9V to latch or unlatch. We automate this process using a microcontroller that senses the House Bank voltage. When the voltage is rising (charging) to a preset level it sends a pulse to a L298N motor driver that triggers the Latching Relay. When the voltage falls back below a certain preset level (discharging) the microcontroller sends a different pulse to unlatch the Relay. Very much like it was spinning a motor forward or reverse. This automation could also be very easily done using a couple relays in the place of the L298N. And, of course could be done manually with a DPDT switch.all our best,dr

I got this relay for a custom build in my work van to isolate the car’s battery from the house battery when the engine isn’t running. However, I didn’t pay attention to the fact that it was a 'latching' relay. This means once it’s activated, it stays in that state (either open or closed) until the activation wires are reversed. If you're replacing the relay for the listed application, it should work fine—it’s sturdy, well-built, and includes the necessary hardware. But for custom builds, be sure to look for a non-latching relay instead. I am still giving this item 5 stars as it will be good for the right application.

As an electrician I could see how easy it is for somebody to mess up hooking this thing to their RV. I highly recommend you purchase the product and leting Electrician do it for you or teach you how to do it. Half of our electronic Quitman wasn't working in the RV with another older solenoid and plugging this one in its place seems to have done the trick and brought all of the electronics that were working back to life
