Keep your 24V system charged and ready without adding another maintenance task. This 30-amp, 3-bank onboard marine battery charger delivers multi-stage charging and long-term battery care, so you're not troubleshooting before launch.
When one battery bank is drained more than the others, fixed-output charging can leave the wrong battery filling first while the weaker bank is still behind. That can turn into one more thing to check before launch. Distributed-On-Demand Technology automatically senses demand and directs 100% of available charging amps to any one bank or combination of banks. On a 3-bank setup, charging stays focused where it's needed, so you're not swapping connections or wondering which bank is going to come up short next time out.
Batteries that sit partially charged during storage lose capacity over time, and that usually shows up when you're expecting everything to be ready. This unit runs through Charge, Condition, Auto Maintain, and Recondition stages to keep batteries at proper levels between trips. After 21 days in maintain mode, it automatically de-sulfates to restore lost capacity, and it lowers float voltage after 72 hours without a load over 5 amps. You can leave it connected during storage and come back to batteries that are ready to work instead of banks that need troubleshooting before the day even starts.
Multi-bank systems get harder to trust when the charger is locked into the wrong battery profile. This unit has 12 selectable profiles and comes factory set for Flooded (Lead Acid) batteries, with AGM, GEL, LiFePO4, and Calcium/Custom selectable. Matching the profile to the batteries you're running keeps charging behavior consistent across the system, so you're not guessing whether one bank is being pushed too hard or left behind.
Charging problems are a lot harder to sort out when you can't see what the system is doing until a battery comes up weak. Dual digital displays show real-time charging voltage and amperage, while Service and Fault Mode LED indicators flag wiring issues or adverse conditions. You can see what the charger is doing, catch problems sooner, and spend less time chasing down whether the issue is wiring, output, or a battery bank that didn't recover.
Some chargers get picky about AC input, which can complicate charging at home, at the dock, or anywhere power conditions vary. This unit uses 100-240 VAC input at 50-60 Hz with Power Factor Correction and auto-ranging AC input, so it runs off a standard household outlet across a wide input range. That keeps shore-power charging straightforward without needing a dedicated setup just to keep the batteries topped off between trips.

Hi, everyone. Steve here with etrailer. Today we're taking a look together at the ProMariner ProNautic Battery Charger. So if you're running a larger 24-volt marine system, battery management, as you know, can get complicated real quickly, especially if you're trying to keep multiple batteries charged efficiently without overloading your setup. So that's where this comes into play. This is designed to make that process easier.
The ProMariner ProNautic 2430P. So this is gonna be great for large fishing boats, offshore setups, high-demand marine electrical systems, and just boats running multiple battery banks in general. So this is a 24-volt, 30-amp, three-bank onboard marine battery charger. You do get a little wire here and this little black connector here that goes around a cable. And this again, is gonna be a big advantage because it uses smart charging technology.
So I zoomed in pretty close so you can hopefully see all the panel itself better, 'cause there's not much to this unit other than the box itself, the ground wire, and everything here. And then as far as where your cables will come in on the bottom for connecting your wires. And those are all labeled as you can see. So I'm gonna keep that zoomed in here while I talk about it. And again, this uses this smart technology.
It's gonna automatically adjust charging based on the battery condition and the demand. So that's gonna help improve charging efficiency while also supporting long-term battery health. And because this is an onboard charger, you don't have to worry about hauling around portable chargers, reconnecting batteries after every single trip, you just plug this system in, it's gonna handle the rest automatically. And it's been built for tough marine environments. It's got a heavy-duty waterproof and vibration-resistant design and case, that's gonna help it stand up to moisture, heat, and any rough water conditions that are out there.
Another big benefit, it's compact, it's space-saving. It's got a 30-amp charging output, three-bank charging system, and it's got an automatic multi-stage charging with smart battery conditioning technology built in. It's 12 3/8-inches tall, 8 1/2-inches wide, and about 3 1/2-inches thick or tall, whenever it's laying down. So again, folks, this is the ProMariner ProNautic 2430P Battery Charger. I'm Steven with etrailer. Thanks for watching and have a great day.
