To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
UPDATE: I would love to say this a great charger, however I have received two of them and neither of them worked correctly. The first one was DOA when I received it. It cost me $200 to have it installed, only to have my installer tell me it was not working correctly, and pull it out. I sent that back to Amazon, but was out the $200 installation fee.
Stupidly, I bought a second one because I like the company. I again paid $200 to have this installed in my RV under the passenger seat where apparently it needs to go. This one worked, so I was happy with it. It worked well, in fact, for all of three days into my vacation, then I noticed on my battery monitor that there was no charge whatsoever coming from my alternator. On vacation, 2000 miles from home, I had to drive two hours to an RV place to have this unit taken out. Removal and reconnection of my old wiring cost me $220 this time. Now I am up to $620 in installation and removal fees.
I drove the rest of my vacation with the straight alternator and was fine. When I returned I called Amazon and they agreed to take back the unit even though it was past the 30 days. They said they would charge a restocking fee but that the fee would be waived once they received the unit. They now refuse to refund the 45.00 restocking fee because the unit is not in re-sellable condition, to which I can only say, Of Course not!
The long and short of it is that it cost me $665 to try to make this work and as much as I like the company, it doesn't. The units I got were defective and I would not order this again from them.
I bought this one for my sprinter van conversion to charge 4 lithium batteries,connected to the alternator using 0/2 wire 16 f ANL fuses 60 amp just next to each end of the wire and emergency blue sea 300 amp battery switch after setting everything started the van it start charging and under 10 minutes it just stop working overheated really bad and don’t start again try to reach customer service and the phone is always busy and by mail it takes forever to receive a response there is not even and option to send the unit for repair or change is just like you got a lemon enjoy it!
Believe the bad reviews this company is producing garbage and not backing it up no customer service and no refunds. I have used mine less than 6 months and under 100 hours and it doesn’t work and blows 250 amp fuses could end up costing you way more the company is selling garbage in a box and literally says we don’t care and is aware there getting away with it, I had electrical company look inside after no response from the company and they said it is made as cheaply as possible. There are much better options pass on these poorly constructed and zero customer service companies just because there on Amazon or some you tubers use the product.
It would have been a great product for my needs of charging my RV house lithium batteries wIth the engine alternator. It was pretty easy to installed and worked as advertised for a few months. Then for no apparent reason it stopped working. Worse still it drained the engine battery. I had to physically disconnect the wiring. I submitted a support ticket with Renogy but never got a response. I replaced it with a Victron which has been rock solid.
I've spent at least four hours (mostly on hold) over four different calls to sort out a tech issue with this charger and the techs were wrong every time. They misdiagnosed a condition where the charger would start charging two Lithium Ion Batteries and then the charging amperage would start declining after about 5 minutes until it eventually went to zero and shut off the charger. They first said it was a bad motherboard then, after changing out the unit for a replacement only to get the same performance from the new unit, they said it was a wrong dip switch setting. Answer (after a lot of trail and error on my own) the optional current limiting circuit needs to be connected because too much amperage from the alternator was choking the charger. Two weeks of my life I'll never get back... Also, I paid for a 60 amp charger but will only output 29 amps if I don't want it to overload and fail. Very disappointing.
Unit failed after 10 months. Trying to get a warranty replacement is not easy. Over the course of 2 weeks I've contacted them 5 times. The last attempt was via a phone call. Be prepared to wait over 30 minutes to talk to someone. I think I'll eventually get a warranty replacement, but it will probably take over a month from the time I initially contact Renogy to the time I actually get the failed unit replaced. I've bought a lot o Renogy stuff in the past, but those days are over due to their post sale support.
Installed into my Australian built Winnebago motorhome built on an Iveco Daily 50C truck. Installation completed with over sized cables and appropriate fuses. It operated perfectly producing a full 60 AMP charge to my 400 AH LiFePO4 Lithium battery bank. However, after a continuous run of about three hours an intense electrical burning smell was detected and the unit no longer operates. I did get an initial response from my supplier asking for more details and photos which I provided, but I am no longer getting any response from Sold by: Amazon Export Sales LLC
Worked great but then failed after 3 months. Customer Support is non existent from Renogy. On hold for over 1.5 hrs twice. Don't respond to e-mails until you talk to someone. Now they want to test it and determine whether they will replace it. Never spoke with a tech person that was slightly knowledgable beyond book knowledge.
