NOCO Genius GEN5X3, 3-Bank, 15A (5A/Bank) Smart Marine Battery Charger, 12V Waterproof Onboard Boat Charger, Battery Maintainer and Desulfator for AGM, Lithium (LiFePO4) and Deep-Cycle Batteries

Purpose:-Using this as an on board charger for my 36v 00' EZGO TXT Gold Cart.Charging:Three 12v Lithium LiFePO4 batteriesLocation:Mounted to the underside of the drivers seat.Note:Works very well at charging. When I initially used it (on new batteries) it took about 8hrs to get them all way charged. Slight warning that it did get pretty hot the first few hours. Ever since though, hasn't taken as long to charge because I haven't run them down that low yet. I do like that it will stop the charging on each individual battery when they are fully charged. It doesn't charge them all in a a few hours but it is plenty fast and leaps and bounds better than my old one.Impressions:CompactDurableSmartGets somewhat hotWorth the money**The electrical tape was a choice and not a necessity**

Last year we purchased Li batteries for my trolling motor. Didn't know that you need a Li charger too. I had a portable one but it needed to be switched to charge both batteries. This eliminated all the swapping hooking up and unhook each time I wanted to go fishing. It also charges my starting lead acid battery too all with only one plug. Works great! It also maintains all three batteries automatically and remembers the last setting, so I don't have to get into the boat each time I charge. Great value for the price. Install depends on your boat and how easy or hard it is to run wires. I did have to lengthen the wires to the starting battery as it is in the very back of the boat. The charger also tells you if you switched the wire polarity. I did have to install a switch between the two Li batteries. As this doesn't charge a 24V system but will charge each battery separately. Just need to remember to switch it back to 24V when using the trolling motor and then back to 2x 12V when charging.

charging 3 batteries on small 17 foot boat . compact and works great. easy to install and display for charing is well lit.

we use this for our bass boat and its wonderful. if your boat is a no go then get a noco!

Had to replace my charger in my 10 year old bass tracker. I want to upgrade the Trolling motor to Lithium so this charger allows for each channel to be adjusted for battery type. Very easy install and very happy with the visual gauge on the charger.

Overall Great product. A couple small issues that might be user error. One being that I get a better charge on the standard 12V setting than I do on the lithium setting, even though I have lithium batteries. Also, I'm only getting about 190 watts max when I have the generator running. However, that may be the limit for a deep cycle charging system. Plenty of cord, everything is plug n play so very easy to use.

I purchase this 5x3 charger for my boat about 1.5 years ago. I noticed one of the charging banks was showing a over heat condition, check the battery, swapped banks same issue temp was in low 70s so not hot at all .Contacted Noco they had me send it in the tested it and sent me a new replacement! No Hassel,. Took a few weeks but all is great! The customer support is the best !! Highly recommend this company for you marine charger needs

Would not buy it again, NOCO had a good reputation with me and their Gen1 onboard chargers. Well this one broke in 20 minutes of first use! Very disappointed, It sat in a box new in dry storage at 70F for 2 and a half years, Finally got around to hooking it up to 3 12 volt SLA batteries that were already at 13.1 Volts DC all it had to do was float charge them to 13.5 volts and it just shut off and will not turn back on. Now i have to see what their warranty will do and it claims user will pay shipping fees and service repair fees if its past 2 years from date of purchase! sounds like BS the item is clearly new, just opened was not in service for that time and it comes back to a manufacturing defect. Please send a replacement for your faulty product, this is a bad way to run a business if the person never tested the item till recently. Only a manufacturing defect would of caused this. Ive had NOCO charges that ran for 5 years straight without a single issue. Seems like they cheeped out on parts now with these microcontrollers. Very disappointed and would not buy any of the NOCO micro charger units ever again!! They have lost my future purchases based on this experience and terms of the Warranty. A company should back up their faulty products. every industry has a manufacturing defect at some point and few companies are willing to admit what percentage of products fail from poor component selection and installation. Poor quality control standards must exist with NO testing of products prior to shipping to the consumer. cause had it been tested it would have broken in the factory.
