NOCO Genius2x4 Multi-Bank Charger Diagram

The NOCO Genius quickly charges and maintains up to (4) 6V and 12V batteries, using a standard household outlet. 4 Battery banks allow you to charge multiple lead acid and lithium-ion batteries rated up to 40 amp-hours, it's a great charger to have around the garage for motorcycles, ATVs, snowmobiles, personal watercraft, lawn mowers, and other equipment. With 4 selectable battery profiles, multi-stage charging, and advanced safety features, this Genius smart charger makes it easy to keep your batteries in peak condition.


User-Friendly Interface with LED Indicators

NOCO Genius 2X4 LED Charging Indicators

This Genius smart charger was designed to provide a simple, user-friendly experience. The mode buttons allow you to easily cycle through the unit's charge settings on each connection. Back-lit LED indicators let you verify that the unit is operating correctly, and they allow it to be easily operated at night. These indicators signal the unit's charge status, selected charging mode, and alert you to potential performance issues or errors.


NOCO Genius2x4 Advanced Battery Error Diagnostics

These indicators allow you to quickly identify a problem with the battery or connection. So you don't have to waste time guessing if the battery voltage is too high or too low for your selected mode, or worry about damage from a reversed polarity connection to a battery.


CANbus electrical systems found on BMW, Ducati, Triumph and Harley-Davidson motorcycles disable the 12-volt charging port when the ignition is off and won't work with traditional battery chargers. However, CANbus enabled technology allows the battery charger to send a voltage signal that automatically opens, and allows charging directly through the 12-volt accessory port. The charger works with vehicles with start-stop and CANbus systems.


4 Battery Charging Modes

NOCO Genius2X4 Genius Battery Charger Charging Modes Explained

This Genius smart charger has 4 selectable charging modes that let you quickly switch between charging different lead-acid and lithium-ion battery types at different voltages. Traditional battery chargers generally only work with a specific voltage or battery type, like lithium-ion or AGM batteries, or only in special circumstances like charging in cold environments. This NOCO charger gives you the versatility to tackle different battery types and charging situations in one charger.


The charger works with 6V and 12V wet cell, gel cell, enhanced flooded, calcium, maintenance free, AGM, and lithium-ion batteries with battery management systems (BMS). A built-in battery desulfator restores lost capacity to sulfated and old batteries.


Multi-Stage Smart Charging Technology

The NOCO GEN series smart charger uses an 8-stage charging cycle to quickly and efficiently charge your battery. This ensures that the battery safely reaches maximum capacity without being overcharged.


NOCO GEN5X3 Genius Battery Charger Advanced Smart Charging Technology

In the first step of the charging process, the charger will analyze the battery's condition and state of charge. The charger then uses this data to diagnose the battery's health and ensure it can be safely charged. If the battery is deeply discharged or sulfated, the charger will automatically enter the recovery stage to repair the battery by pulsing small amounts of current.


Once the unit has determined that the battery's condition is stable, it will initialize the charging process by providing a constant, gentle charge. The charger gradually increases the charge during the bulk stage and quickly charges the battery to 80-percent capacity.


As the battery nears full charge, the charger enters the absorption stage and delivers small amounts of current to limit battery gassing and safely bring the battery to 90-percent capacity. The charger will then begin optimization of the battery, bringing it to full capacity and optimizing it for increased run time and performance.


The final step of the charging process, maintenance, monitors the battery for drops in power and supplies the correct current to keep it fully charged. If a drop in voltage is detected, the charger will begin the optimization cycle to keep the battery fully charged.


X-Connect Battery Clamps, Eyelets, and Extension Cables

NOCO Genius2X4 X-Connect Battery Clamps, Eyelets, and Extension Cords

The X-Connect battery clamps, eyelets, and extension cords included with the charger are built for rugged versatility around the garage. Unlike typical, plastic battery clamps, the clamps are constructed entirely of metal, ensuring maximum conductivity. The eyelets connect directly to batteries. The lie-flat design ensures maximum contact with terminals. And the (4) 10' extension cables provide extended reach when needed. All of these accessories feature over-molded connection points that stand up to heavy use and keep connections safe from the elements. Built-in 4-amp fuses protect all your connection against dangerous overloads.


Rugged Weatherproof Design

The Genius charger comes with over-molded connection points to protect the unit from dirt, dust, and water. The unit has an IP6X rating, meaning it can withstand splashing water from all directions, and it's completely sealed against solid particles bigger than 1-mm. A durable X-connect plug ensures a weathertight connection when attaching the clamps to the charger.


The housing is made from tough Lexan resin that protects the internal electronics against impacts. The unit can handle being dropped, kicked over, and just about anything else your day brings.


Interchangeable X-Connect Accessories

This Genius smart charger also features unique X-Connect plugs that let you disconnect the battery clamps, or eyelets and attach other X-Connect accessories (all sold separately) for versatile plug-and-play charging solutions. Access your vehicle's battery through charging ports with the OBDII connector, or the 12V male plug. Add a 12V indicator so you can more easily track the progress of the battery as it's charged. With a large variety of available accessories the charger can be outfitted to meet your application's specific charging needs.

Video Transcript for Review of NOCO Battery Charger - Battery Charger - NOC57FR

Jeff Hello everybody, this is Jeff at etrailer.com. Today we're going to take a look at this NOCO genius 8 AMP, 4-bank, smart 6 Volt and 12 Volt battery charger. Now, this AC to DC smart charger will quickly charge and maintain up to four batteries. So it's perfect for motorcycles, ATVs, personal watercraft, lawnmowers, and other equipment. It is a nice, durable resin housing. It's very rugged, and water resistant, so its perfect for on or off-board applications.

And it is a compact smart charger, which will draw power from an AC wall outlet to charge and maintain up to four batteries at two AMPs each. Now, they do offer four different types of AC cables. This one is the North American version that we just plug in the cord right here, and then plug it into your wall outlet. They also give you a European version, an Australian version, and a UK version AC cable. The cable lengths are about 75 inches, and again you just unplug it here, plug in which cable you need for you application.

Now over here, they offer four battery clamps with the integrated eyelets for a nice spark-proof, and they have reverse polarity protection. The lengths on these are about 21 inches, and if you noticed, they have an inline fuse holder on them. And it protects the wire in each connection against dangerous over current. And again, there's four of those. They also give you four x-connect 10 foot extension cables, which will provide added reach for your connections.

Inaudible 00:01:32 plug that into here, and extend it an extra 10 feet. And there's four of those. Now I want to zoom in and talk about the charger. The charger itself, you can see, has four battery banks. It allows multiple 6 Volt and 12 Volt batteries to be charged simultaneously and its a very simple operation, has the mode buttons that control everything, and the LED indicators will light up and tell you the situation that's happening as you turn it on.

It does offer multiple battery profiles to let you charge a variety of battery types at different voltages. The 6 Volt mode, they have a normal charge. 12 Volt mode, they have normal, AGM, and lithium ion. - Now this does use a multi-stage charging algorithm, which will charge two times faster than traditional chargers, without overcharging. Basically what it'll do, is it'll analyze battery condition and provide a customized charge for that battery, and it also offers a built-in battery desulfator to restore lost battery capacity. Now, they do offer x-connect series accessories, which we do sell separately. It'll provide connections for additional applications. Those x-connect accessories are sold separately, and they're listed on this product page as a related product. Few specs on this, the application is for 6 Volt and 12 Volt batteries up to 40 AMP hours. The battery types this supports is a wet cell, GEL cell, AGM, and enhanced flooded, maintenance free, and lithium ion. Now, one note is the lithium ion batteries must have the BMS, which is the battery management system, for it to operate with this charger. Number, again, of battery banks is four. Maximum charging amperage is 8 AMPs, which is 2 AMPs per battery bank. Maximum power consumption is 120 Watts. Last thing I'm gonna do is give you some dimensions on this. The weight of it is about 3, just under 4 pounds, about 3.9 pounds. Overall width from this side to this side, It's gonna be right about 9 and 3/8 inches long. The width on it, now if we include the--where the cables stick out, total width to there is gonna be about 6 and 1/2 inches. Just the box by itself, width is about 5 and 3/4 inches. And then the overall height from the bottom to the very top is right at 2 and 1/4 inches. It does come with a nice owners manual, to describe how the connections are made and how it operates. Couple screws for mounting this, but that should do it for the review on this NOCO genius, 8 AMP, four bank, smart, 6 Volt and 12 Volt battery charger..

Contacted etrailer.com about charging K2 Energy Lithium Ion marine batteries. They took the time to contact NOCO Genius chargers to get me the correct answers. NOCO said absolutely that this would be the correct charger for lithium ion marine batteries.

I am now confident that my investment of Lithium batteries will get the correct charge they require. The NOCO genius charger is lighter and smaller than my previous charger allowing more room and less weight in my boat.

Good,but it does boil off battery fluid on my Yuasa battery. I have the charger on a timer to operate once a week for 3 hours to keep the batteries topped up, without fluid loss.

Review from a similar NOCO Genius in Battery Charger


We have had this charger for about a year now. We use it to recharge batteries for the camper and boat, and maintain them over the off season. It has worked great to charge both our conventional wet cell and AGM 12 volt batteries. It charges the batteries in a reasonable amount of time and, due to the "smart" multi-stage charging technology built into the charger, we do not have to worry about over charging the batteries. I highly recommend this charger.

Review from a similar NOCO Genius in Battery Charger


pretty expensive for a trickle charger, BUT it appears to be made from better than average materials, and it is compatible with wet cell, AGM, and even Li-ion. The battery clamps are really nice-looking, quality constructed, top grade material. It appears to me to be a really top shelf, state of the art, highly-optioned, trickle charger. 3yr warranty.

it has been working pretty much 247. Still working as advertised.

Wow! Your delivery and tracking system is excellent, very personal and accurate. My new battery charger is here and currently (yes pun intended) in use on my RV.

Review from a similar NOCO Genius in Battery Charger


simple to use, relatively fast charging. Particularly like that it has both alligator clamps and ring terminals. "Intelligent" charge controller quickly charges a dead battery but also dials back to trickle charges then off when full for better battery life (and less evaporation on non-sealed batteries) so you can leave the battery attached for optimum over winter storage.

Review from a similar NOCO Genius in Battery Charger


8 months after purchasing my NOCO Genius the battery on my truck went dead, best I could get was a little clicking, no lights, radio, nothing. My first thought was a lose connection however after checking and finding everything in order I hooked up the NOCO, turned it on and fired the truck right up. This was my first experience with this type of device and did not know what to expect, I was completely impressed by how well the NOCO Genius worked! It is a must have and will always be a part of my onboard took kit!

I bought two of the Noco 2 amp battery maintainers and am pleased with both. Using them outside in a dry location to maintain car batteries. Convenient connect/disconnect and easy to read and understand status LEDs.

Review from a similar NOCO Genius in Battery Charger


The Noco G1100 is one of four items I purchased from etrailer to make a portable 12 volt power pack for camping. I wanted to make my own power pack because many available do not have the power I want, have gimmicky features I do not want, and the batteries are not usually user-replaceable. Noco’s X-connect feature made this very easy. I also ordered a HM082BKS box for a U1 type battery, a GC010 12 volt female connector (cigarette lighter type), a GC013 male-to-male coupler, and a GC004 10 foot extension. From elsewhere I purchased a 35 amp/hour U1 battery with screw terminals (Interstate DCM0035) to fit in the box. I unscrewed the battery clamps from the charger output cable which left ring terminals I then attached directly to the battery. Leaving this part attached to the battery, the X-connect feature allows me to: (1) hook up the charger to the battery, or, (2) with the GC013 coupler, attach the female connector for camping. I expect to use this power pack for my CPAP, which can run directly from 12 volts DC (without an inverter), and eventually other items, such as a 12 volt TV. I can also power and charge USB devices with a USB adapter/charger which plugs into the 12 volt female connector. I’ll be testing the setup during an upcoming trip but have no reason to doubt it will work as expected. Of course, you could do the same thing with a bigger battery with the proper charger and battery box. The X-Connect feature is great and I should not have to open the box until I need to replace the battery.

I have attached pictures which show (1) the charger attached to the battery, (2) 12 v female connector connected to the battery with the male coupler, and, (3) the unit ready for travel. The little dust cap from the X-Connect is attached to the battery box strap.

I like that it's weather proof and has selectable charging. It charges car batteries quickly, but I mostly use it to charge the chassis batteries in my motorhome while it's in storage. The only negative I've found is that it doesn't handle Arizona summers, but I haven't found a charger that does. I use it for a few hours early in the morning and that seems to be sufficient. I installed the NOCO eyelet terminal accessory on each set of batteries.

Having used THE NOCO Genius2 battery charger for greater than 1 years, I can say that I am completely satisfied with form and function of the device. I use the charger to maintain fresh battery charge for my RV trailer. I like the compact, portability and weight of the unit. The indicator lights keep me informed of the battery charge status. I consider this purchase as one of my best purchases of all my RV gear. Thanks for an excellent product.

Review from a similar NOCO Genius in Battery Charger


My previous charger died and took the entire battery bank with it. The Noco Genius was easy to install and plug in to a regular 110 socket so no splicing electrical hard wires. The cord was a little short so I mounted it on the genset sound shield then threaded the power cord through the top of the back bulkhead to the power source. Easy to see status lights, absolutely automatic sensing so it will not cook your batteries. I love it!

  • Charger Recommendation for RV with 6 Volt Battery Bank
    For a battery bank charger that is compatible with 6 volt battery banks like yours you could use the NOCO Genius Multi Bank Charger part # NOC57FR which you'd run to each battery to charge them individually. This would give each of your batteries the best charge so that when it's time to use the RV again they'd be the healthiest. I attached a review video for this for you to check out as well.

    To answer your first question, not exactly; your 7 way trailer plug will have a 12v feed but it is only suitable for maintaining the trailer's battery and not actually providing a full charge. When it comes to charging the sleds, you're not going to want to directly charge them from the trailer battery and you will want to use a battery charger that is powered by the trailer battery. However there are two issues with this that will need to be taken into consideration. First, in order...
