Bought on 10/2023 and by 4/2024 3rd bank was dead. Blows fuses and will not register any isolated battery on that bank. Bass Pro won't honor for an exchange unless you purchased their extended warranty but Noco has a 3 warranty already from manufacturer. So now comes the weeks of waiting for a response from their costumer service and sending item back, then waiting for their analysis and refund. Just in time for the fishing season.

Easy to install. Too early to tell about how it will perform, but it is simple to understand how it operates. It did charge my new standard deep cycle batteries to full charge after a day or so. This unit is a 15 amp charger/maintainer while my previous unit, a Cabela's 20 amp - 3 bank worked well for 5 years. The manufacturer for my old unit would not respond for questions I had about it. I like that the NOCO can also charge Lithium batteries should I make that change.

Having a four battery system and having your "high end" charger go out three months after the warranty expires is frustrating to say the least. Looking for solutions, I came across a video suggesting that using two low cost dual bank chargers was a good alternative. If one goes out, replacing it is a lot less of a concern. This is working great so far. We'll see how it holds up in the future. I just use a plug splitter to marry the two plugins and still have a single extension cord to the boat.
