NOCO Genius GEN5X1, 1-Bank, 5-Amp (5-Amp Per Bank) Fully-Automatic Smart Marine Charger, 12V Onboard Battery Charger, Battery Maintainer And Battery Desulfator With Temperature Compensation

The charger is a fantastic product in and of itself. It works great for my small LiFePO4 battery bank, and I have no complaints about it. br>br>ON THE OTHER HAND. br>br>If you're like me and cut the cable to shorten it, you'll notice a smaller set of wires in between the two power cables in that wire. "What are these for?" you might wonder. " Nonetheless, you go on. " It's as simple as plugging it in and waiting for the magic to happen. It's not going to work. The device is giving you a temperature error. br>br>Those two wires are for a thermistor that is located in the cable junction between the solid black and split red/black wires. The Genius believes it is too cold outside to charge them because they are disconnected from the thermistor. Thankfully, there is a simple solution. br>br> Because the thermistor has a negative thermal coefficient, you can simply strip and twist the two tiny wires together to bring the device back to life; however, you'll lose any ambient temperature sensing functionality, and the device will simply assume it's nice and toasty outside all of the time (no low temp optimized charging). It's still preferable to it not working at all! br>br>To summarize, if you cut the wire short, do so after it splits into two red and black cables, or expect to lose thermal functionality.

Compared to my old charger, this one gives me more run time. When charging, this charger does not become warm or hot to the touch. There are seven on both the positive and negative charging leads. I feel very safe leaving this charger plugged in all the time, and I wish I could give it 6 stars because it has 5 amp fuses to prevent any issues. I would strongly suggest it.

I bought it because I was having battery drain issues in my car, and no one could figure out what was causing it after three visits to different shops. Instead of replacing batteries on a regular basis, I decided that a trickle charger might be the way to go. This one was simple to install beneath the hood and appears to be long-lasting. Since using this charger, I haven't had any problems with my battery. When I park my car in the garage these days, I simply plug it in to keep the battery charged. I waited a few months before writing this review to make sure it worked as well as I had hoped.

From the outside, this unit appears to be very well constructed. I've only used it three times, but it's worked great so far. Because of one concern, the unit gets hot, I only gave it a three-star rating. I'm charging it in a 77°F temperature-controlled room, and the unit is measuring 135°F while charging. This is something that worries me. What would the temperature be like if the unit was outside in the 90s or 100s? I'm concerned because heat destroys. This unit's future will be determined by the passage of time.

I have an electric trolling motor battery that I'd like to keep fully charged when I'm not using the boat, but I'm too damned lazy to get out the charger, set it up, and then unhook it once the battery is fully charged so it doesn't short out in the rain. This charger allows me to simply plug it into a dock outlet and forget about it.

It's a cinch to charge your expensive marine batteries in a neat and efficient manner. Only a 24v system was available on "Business," my boat's name. An extra battery was required due to the installation of a 36v trolling motor. It's a lot better than switching from a 2 to a 3 bank. I purchased a double receptacle plug after adding this. It looks great and performs admirably, so I don't have to worry about my batteries when I'm on the road for business.

This is something I should have purchased years ago. I have two batteries, one to start the outboard and the other to power the electronics trolling motor, as well as two Hummingbird Helix 7 and two Hummingbird Helix 7, CHIRP MSI GPS G3N on the bow. Because I don't want to risk engine interference, I haven't connected them to the main engine through the battery isolator. My starting battery is charged by my outboard motor. This thing works great (get the NOCO GCP1 15 Amp AC Port Plug, 125 Volt Power Inlet Socket, and Waterproof Electrical Outlet Receptacle Box with 16-Volt Waterproof Electrical Outlet Receptacle Box with 16-Volt Waterproof Electrical Outlet Receptacle Box with 16-Volt Waterproof Electrical Outlet Receptacle Box with 16-Volt Waterproof Electrical Outlet Receptacle Inch Integrated Outdoor Extension Cord) so that all you have to do when you get home is plug your extension cord in. The unit is in charge of everything.

It's a little difficult to set up. I placed it side-by-side in my Ranger. Off the beaten path. I needed to make a bracket to mount the front panel on so I could see it. It turned out to be a long and arduous task. It appears to function properly once installed, but only time will tell. It would be easier to mount it in the engine compartment of a road vehicle, but in this case, mounting brackets that could be used flat or on its side would have been preferable.
