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 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.

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.

I love that this charger. It will charge many types of batteries including lithium batteries. I checked with the manufacturer of the lithium batteries and he confirmed that this charger would do the job!....

I have only just started using the charger as a charger it works well but the cords were short for use in a boat and you need to BOLT on any extensions or you will void the warranty and the 2 little screws they give you are pretty useless as its a rather heavy unit for a battery charger, they did have a good chat response on thier website, yes I would recommend it with the same concerns mentioned above, I have 4 batteries in my boat so only needing one charger is great, also it can charge lithium batteries, interesting Minn kota just announced they have one, assuming you can even get one as most of thier items are out of stock

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 .
