NOCOGenius GENPRO10X4: 4-Bank, 40A Onboard Battery Charger - 10A Per Bank, 12V Waterproof Marine Charger with Overcharge Protection & Temperature Compensation – for Lead-Acid & Lithium Batterie

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.

Outstanding

Works great was easy to install and set up. Charges lead acid and lithium batteries all at the same time.

Does exactly what it supposed to do charges my batteries on my boat plug it up let it charge up my batteries for a worry free day on the water the next day and it seems very heavy so that tells me hopefully it’s very well designed and built.

I kept it stored until my LiFePO4 and AGM marine batteries arrived, now they’re on the charger. I easily selected the type and the LEDs let me know each battery was charging. I’ll eventually mount this in my bass boat where I’ve already installed the charging port for easy hook-up. The overall size is perfect for mounting in a space behind my live-wells. I no longer need individual chargers and multiple extension cords; this unit can handle it all, and I have a free charging port if I decide to add a spare LiFePO4 battery.

I installed this 4 bank charger last year to charge my Battle Born Lithium Batteries. So far the charger has performed flawlessly. It charges the batteries over night and has kept them in balance. The question now remain how long with this unit last. My last charger was a Minn Kota which only lasted 4 years before one of the banks started having issues. before mine Kota I had Dual Pro charger which never got me more than two seasons before they crapped the bed. Depending upon how long this charger last will determine my next charger replacement. The NOCO has far better features than any of the other chargers so if it reached 4 year, I'll by another. Hope this is helpful to someone.

System was a significant upgrade to my battery management on a 43' boat. Many guys at work use the same brand for their boats, as well. Recommended, and worth the price.

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.
