Renogy 12V 60A DC to DC On-Board Battery Charger for Flooded, Gel, AGM, and Lithium, Using Multi-Stage Charging in RVs, Commercial Vehicles, Boats, Yachts, 60A

So far no issues. Seems to be well made and had good terminals People claiming it gets too hot are probably not using the right wiring or terminals. It is highly recommended to use pure copper 4 gauge wire and copper terminals. Do not use CCA wire or cheap terminals. If you're not running it at half power don't go smaller than 4 gauge wire. Make sure your alternator can handle a 75 to 90 amp load on top of what your vehicle uses. I correct wiring will cause high resistance and heat, the heat transfers to the circuit board and will damage the unit. It does get hot to the touch but not hot enough to burn. Read the instructions and make sure the dip switches are set properly according to the battery you're using.

Was delivered on time and worked as charm. I liked it.

I installed the device correctly with the ignition wire that only turns on the device when the engine is running. I talked with renogy twice and we confirmed all the connections were perfect.. This device continued to drain my starter battery and it was also popping 100 amp in line fuses between the starter battery and the DC charger, as I have braided 4AWG going from the starter battery to this charger per the manual. renogy tried to tell me that my starter battery was no good. I informed them that if my starter battery was not providing enough electricity the Red fault light would be on, which is one of the design outputs of their DC charger, per thier manual. I also explained to them if there’s not enough electricity coming from the starter battery it’s not going to pop 100 amp breaker repeatedly when i'm driving. i am military and I called back to duty after i bought this charger so I couldn’t install this until three months after I bought it. amazon they said there’s no return option available. I noticed on the 40 amp charger. They did an upgrade which is an automatic alternator checker so I think this problem is well known. UPDATE: I contacted Renogy 10 days ago and they asked for photos of my installation of the charger which was done per the manual. I informed them the device failed right out of the box. I sent the photos in and they said it would be 24-48hr and i haven’t heard from them after 10 days. I then called them and was transferred many times and received the run around. they are now asking for me to conduct resistance testing on thier own device not connected to anything and to test my starter battery. they said if they’re happy with these results, they’ll send me a return authorization for me to send the device back to them. They will test it and either send it back to me or send another device back to me. This whole process will take many many weeks. so ridiculous. I have no faith in their device now. I’ve never had a company ask me to do electrical tests on their own device to ensure that it works before i can return it to them.

Working as advertised but found out it’s low efficiency - while delivering 57A it takes 89A from alternator. Also there is no low voltage shut down so when car slow and stop on red light and RPM are low voltage drop below 11V and car (radio lights) not functioning correctly while it still sucks all these Amps.
