GENPRO10X4 12V 40A 4-Bank OnBoard Marine Battery Charger & Maintainer | Charges 4 Batteries at Once, IP68 Waterproof, Overcharge Protection, Temperature Compensation, For Lead-Acid & Lithium

These work great. We used 3 of them and a 3 bank unit in 2 cycle pubs to replace faulty 12v & 48v chargers these now charge the battery's individually instead of as a bank & let you know if there is a battery fault which battery it is.

Love the this product best thing that I brought on my boat i am really loving how they have a prebuilt 5 amp fuse making easier for me to hook up and play and don’t have to go buy fuses to protect my expensive lithium batteries! On top of anything i can not say how fast it changes my battery it is kinda of heavy but, its not the end of the world great value for my money and good investment towards my boat. I loved how NOCO functionality works made it super easy for older gens and younger adults. But overall NOCO is evolution for newer boats stay safe yall!

I switched the four batteries in my pontoon boat to lithium so I had to get a new charger. I purchased this charger and have been very happy that i did. My batteries can "talk" to an app on my phone and, from what I can tell, this charger is a perfect fit with the new batteries (I have been using this for a year already). I definitely recommend this product and would buy it again!

Installing this to replace an older NOCO 4-Bank charger that did not recognize different battery types. I have a single bank NOCO Genius for my dedicated lithium battery for my graphs. Never had a problem over several years of use. Expect this NOCO to provide similar excellent service. Be aware that this does NOT include an AC power port for your boat or RV. You need to order an AC power port (e.g., NOCO GCP1) separately. Without the power port you have to plug the charger directly into your extension cord. My boat has a power port but I intend to sell the old NOCO charger and include that power port with the sale.

NOCO has great products, this one is certainly fantastic. The weight of the charger requires some care in mounting but nothing too difficult. I use it for 3 100aH lithium batteries and on traditional lead acid. Having 10 amp charging for each battery ensures they are all recharged in just a few hours. Quality item. Leads are plenty long and the connections are perfect for marine batteries.

NOCO is known for reliability and this is exactly that. Doesn't get super hot by any means so it's safe. I really like that you set the mode and you can see the charge state instantly.

I love this charger. Pros: Each of the four charging banks can be set for wet cell, AGM, or Lithium batteries. I use it to charge four lithium batteries in my boat. Each battery type has a different indicatory light and charge indicator lights let you know what stage of charge the battery is in. When a battery is charged, you see a nice, bright green indicator. Great charger. Cons: It's expensive (but it's got the features and battery management I need), big and heavy.

I made a poor choice in ordering this. I'd purchased four LiFePO4 batteries for a power bank. The manual for those batteries indicated they should be charged independently before connecting them in parallel. This fit the bill. And it seemed to work on the three or four occasions I've used it (although it indicated a problem with one of the batteries, and didn't charge it, on one occasion but not the other occasions). Unfortunately, the four channels can't be run in parallel mode, so it can charge the entire wired-up bank at only 10A. I was hoping it would be a suitable component for my overland truck setup - to take advantage of "shore power" - but it's big and heavy and would take forever to charge the bank. It seems sturdy and well-made. I didn't have any reason to try out the other modes or the more advanced features.

Great seller and product seems very very high quality and in perfect working order.

excellent in bord charger,my lowrider batteries are now always full charge

Buenas tardes a ver si me dan respuesta Amazon o el vendedor todavía no va el año que compre este cargador y me está fallando quiero saber qué procede para la garantía que es de un año no ? Anexo foto, marca falla de carga en un banco y ya se revisó todo y el cargador se reseteó etc pero sigue marcando igual

Decepcionante. Este cargador de 12 V tiene 4 salidas. Una o dos veces al día tengo que reiniciar una o dos salidas, o desconectar y volver a conectar el cargador. Se quedan inutilizables y no cargan las baterías. A veces, el estado indica un error. Otras veces, simplemente indica que las baterías están cargadas cuando no es así. Se dice que se puede dejar activado el modo de carga de las baterías y que mantendrá la carga. No lo hace sin intervención manual diaria.

The charger is small enough but powerful enough to charge all four batteries. 4 of my buddies have bought the same charger. Charges fast. Cables are long enough to run to the bow of the boat.
