I installed the 40 amp dc to dc charger with good help from the tech people at Renogy. Yesterday I checked the charge of my house batteries with a volt meter at 13.3 volts and went for a drive. I could barely hear the fan when it came on. When I got back from my shopping I checked the voltage at 14.4 volts. Very happy so far and will probably order the 2000 watt inverter charger today.

Great charger - but watch your fuses

I really like this charger. Easily charges my house battery and isolates my starter battery. My only complaint is while it's nominally a 20A charger, mine routinely draws 30A. I installed the recommended 30A fuses, but I kept blowing them so I've had to replace with larger. Not a big deal, and the extra power is kinda nice.
I would recommend this to a friend!

Verified Purchase:Yes
Very well made and easy to install unit. Using it to charge Li batteries from lead acid batteries and conventional alternator in tow vehicle. It has performed flawlessly thus far and is easy to customize charging parameters.

I do more driving then I do camping so the DC to DC charger was the perfect choice for me to keep my house battery charged up and ready. It was very easy to install and set up.

Bought this for my Sprinter Camper conversion.
Charges my 2- large AGM batteries quickly while driving.
Extremely happy so far.
Far easier and much more reliable than my original setup.

I installed 2 weeks ago and so far the unit seems to perform well but it is louder than I thought it would be.

Nice addition for charging on the road

I mounted this in the front tub of our teardrop trailer to charge my 100aH lifepo4 battery while going down the road. Nice instructions and it works great. I like the ability to charge at either 10 or 20 amps. I have the D+ cable wired into the running lights of the trailer so I can turn the charger on/off by just turning the running lights on/off.
I would recommend this to a friend!

Running this in my travel trailer and getting up to 38A charging to my four batteries. Using power from the marker lights to turn it on since I need them on for my backup/observation camera anyway.
I would recommend this to a friend!
