Specs:
The rugged NOCO Genius GENPRO series on-board smart charger quickly charges and maintains your 12-volt lead-acid or lithium-ion batteries. Multiple battery bank efficiently charges deep cycle and starter batteries up to 230 amp-hours. It's great for boats, trolling motors, generators, and a wide range of electric vehicles and industrial equipment. With a fully submersible design, this smart charger was built to handle harsh marine environments, while keeping your batteries in peak condition.
This Genius smart charger was designed to provide a simple, user-friendly experience. The mode button allows you to easily cycle through the unit's charge settings. 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.
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.
This Genius smart charger has 4 selectable charging modes that let you quickly switch between charging different lead-acid and lithium-ion battery types. Traditional battery chargers generally only work with a specific 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 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.
Sets of 3/8" eyelets connect the charger to your batteries. Over-molded connection points stand up to heavy usage and keep connections safe from the elements. Built-in 15-amp MINI fuses protect each connection against dangerous overcurrent.
This Genius charger plugs into an available wall outlet to quickly charge and maintain multiple batteries. High-frequency switch-mode technology converts AC power into safe DC power to fully charge batteries. An onboard microcomputer monitors and controls this charging process to minimize power loss and maximize efficiency. Included hardware lets you mount the unit in an enclosed compartment, garage, or workspace.
The table above provides a quick reference for how long it will take the unit to charge batteries with various amp-hours.
This on-board charger was built to handle extreme marine conditions. The unit has an IP68 rating, which means it can handle being fully submerged in water, and it's protected against solid particles like dust or sand. Its ignition protected for safe and worry-free operation around marine engine compartments and fuel tank spaces. Saltwater won't cause issues either. The charger has been thoroughly tested to resist corrosion.
The housing is made from tough Lexan resin that protects the internal electronics against vibration and impacts. The unit can handle being dropped, kicked over, and just about anything else your day brings.
Available AC port plugs (sold separately) from NOCO let you easily setup your GENPRO series charger for plug-and-play charging with any extension cord. The plug creates a "pass through" AC charging port on a surface, so you can quickly connect to the charger when it's mounted inside a compartment on a truck, boat, trailer or RV. This allows you to easily access the charger for charging engine block heaters, trolling motors, batteries, and other equipment. A snap-fit cap creates a watertight seal to protect the connection whenever you're done.

Saltwater tested and ignition protected for safety.I received my noco 4 bank charger very quickly and is an amazing charger for my boat, etrailer had the best price around and they were very helpful in this purchase, only bad thing is I didn’t get the serial number to register the warranty before I mounted, thx etrailer.
This was my first order with etrailer. Price was competitive and delivery was quick. I installed the unit and everything seems to be in working order. I am hoping for years of trouble free service. I did have a few online questions and they were answered in a reasonable amount of time
I have not yet installed the product and my rating is based on numerous online reviews of the product. I can say that dealing with Etrailer was flawless and shipping was very prompt and packaging was excellent. Thank you again for a good experience.
I have been using this product on my pontoon boat charging 4 batteries for almost one year with no trouble. Great product.
I've only had it installed for a few weeks so far but it has worked like a charm so far. I have 1 lithium and 3 lead acid battery's and being able to charge them all at the same time is very convenient. Batteries have been ready to go for all day fishing every time I've been out
It appears to be a good charger. It is supposed to be compatible with the new lithium battery’s.
Delivery was on time and product looks to be in great condition. Can't wait to install and use!
Ordering,as usual,was effortless. The item was received on time and in good condition. I am extremely pleased to deal with the people at ETRAILER. This will be very helpful in keeping my boat batteries charged and ready to go.
this is the ultimate unit for onboard charger installation on dump trailers with dual batteries
Great charger for HD High cca AGM batteries.
Maintains these batteries in the most demanding conditions and is highly weather resistant.
Great service from e-trailer with product on the shelf competitively priced.
Great charger. Does everything that was advertised. Charges batteries in hours. Recomend to a friend.
Great company, fast shipping
Very pleased with this charger! Installed on my boat with 3 batteries, nice upgrade from my old charging system. Even nicer piece than I expected.
Great charger-maintainer for a group 31 AGM battery, I would caution it's use on smaller batteries, especially anything smaller than a group 24.
etrailer is a trusted vendor with great service, good pricing and product availability.
Only had the product for a couple of days but it seems to do exactly what is was intended to.
Good service, prompt shipping and no problems. Very satisfied.
heavy built charger, i would purchase again if I need another one.
