NOCO Genius GENPRO10X4, 4-Bank, 40A (10A/Bank) Smart Marine Battery Charger, 12V Waterproof Onboard Boat Charger, Battery Maintainer and Desulfator for AGM, Lithium (LiFePO4) and Deep-Cycle Batteries

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.

This charger charges my batteries fast and was easy to install

I bought a boat that didn't have an on board charger . The previous owner had been laughing out three different chargers and hooking them up with gator clips every time the put it up . I thought this charger was pretty high prices but since I'm most likely going to upgrade to lithium batteries when one wears out I thought I might as well bite the bullet and invest in the future . I was amazed that the packaging was really nice . It looked great . But more importantly it was very secure and protective of the product inside . It was a bit heavy for an old guy lol . But we got it in . I also bought a receptive from the same company . So I have a really nice waterproof receptical that when I back my boat in the garage , I can just grab my cord and plag it in . One plug and my batteries are charging . No worries about over or undercharging because of the smart technology . No worries about what kind of charger to hook to which battery . It does all the work . I know it's hard to put out that hard earned money . But I'd recommend this charger to anybody who's looking . I open one compartment , peek in and the lights tell my everything is in track .

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.

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 had a battery that was nearly dead and would charge until I bought this product and WALA! The battery charged fully. I have in attached in my boat to charge two cranking batteries and two 12v deep cycle trolling batteries with no problems. Well worth the investment to keep batteries longer.

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.
