Best bang for your buck marine charger
I purchased this 3 bank battery charger as a budget alternative for my bass boat. I have 3 12 volt batteries on board and 2 of the batteries are wired into a 24 volt trolling motor. First I’ll go over the install. If you know how to use a screwdriver and a wrench. You can install this product in your RV camper or boat. Everything is clear and simple to understand. Set up was a breeze after I got it installed. I simply selected my charging mode for my battery type. Confirmed it was on the proper voltage. And powered each bank up and away it went. It’s nice because even after you unplug it. It remembers your settings and defaults back to those settings for each bank. My first trip out with the new charger. We noticed an immediate improvement in battery life. We got an extra hour or so on our batteries on the first charge. We don’t run them dead. But I have a battery meter and I keep track of my usage and fishing times. It seems to have only gotten better as I have allowed the charger to maintain my batteries also. The batteries are on their second season and they’re functioning as if they were brand new. Durability seams very good. It gets tossed around a little in my boat and we have had zero issues with it. I haven’t yet tested out the waterproofing of the unit, thankfully. Because it is installed inside the dry area in my bass boat. Only reason I gave waterproofing a 3 star is because I cannot confirm or deny its quality or lack thereof. For a budget smart charger. These things are great. Buy with confidence!

Highly recommended for boats
Can’t recommend the Noco genius enough. I mounted this in my boat and it works very good.!all you gotta do is plug an extension cord in and it does all the work. Makes charging batteries a breeze. Very simple to hook to battery’s.

Unit Failed in less than 2 years
One of the charging stations failed in less than 2 years. This unit was rarely used. Very disappointed. Update: the manufacturer replaced the unit under warranty with no issues. Good customer service experience.

Perfect for my Boat batteries.
Love this charger for my boat. I have 1 Lead acid Deep Cycle battery for the start and 2 AGM Deep Cycle batteries for the electronics and bow mount trolling Motor. After a fishing trip I just plug it in and it remembered my selection of 12v, AGM. I plan on upgrading to Lithium soon and it has the capability to do that as well

great Li charger
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.

اقراء قبل الشراء/للتثبيت في قارب-مركبه-كرفان متنقل فقط ولا يصلح لتثبيته في كراج او مواقف خارجيه.
هذا المنتج خاص ببطاريات القوارب ويتم تثبيته داخل القوارب او داخل الكرفانات المتنقله لشحن البطاريات فقط. (لا يصلح لتثبيته في مكان ثابت مثل المواقف او كراجات منزلية لوجوب ربطه بشكل مستمر مع البطاريات الا في حال ادخلت على اسلاك التثبيت بعض التعديلات لتصبح اكثر مرونه في النقل).

So easy!
Very easy to install and get going. Took only a few minutes. Only thing I would mention, and this is from my own personal experience in the first few days, is that I have one onboard battery exclusively running my refrigerator. It draws about 4.5-5.5 Amps. The charger maintains the battery, but I have gotten a fault twice now where the charger thinks the battery is no good because it is not keeping charge (especially when the fridge is drawing more than the charger is putting in). So it faults and shuts down that line for charging and my battery discharges. When I shut the fridge off and reset the charger, it will charge that battery back up to full and no issues. So I might need to return this unit for the 10x3 unit to ensure adequate charge is available to maintain the battery with the fridge going. But awesome product and easy to install and use. I would recommend these to everyone.

Awesome Product.
I waited two seasons of charging before this review. I have multiple battery types and different requirements for charging and storing batteries charged and ready for use. This unit is literally plug and play, safe and incredibility reliable for keeping the batteries not only charged but conditioned while in storage over the winter. Highly recommend.
