Built for rugged reliability on and off the water, the Marine 4 is an onboard marine battery charger engineered exclusively for lithium batteries. With 4 channels/banks charging at 10 amps per channel/bank you can rapidly charge up to 4 Dakota Lithium batteries or any 12-volt lithium batteries, including marine, boat, starter, and deep-cycle batteries. This onboard charger is recommended for golf carts, trolling motors, RVs, or any battery bank where multiple 12V batteries are wired in series or parallel. By charging each battery independently this charger ensures your battery bank is balanced and fully charged every time — providing you with maximum performance and increased battery lifespan. Plus the ease of a waterproof charger installed onboard your vehicle saves you time and hassle every time you charge, giving you more time to do what you love. Designed for water this charger is double sealed, with a fully-sealed and waterproof onboard battery charger enclosed in a rugged and shock proof aluminum case with an ingress protection rating of IP67 for use in the coldest and wettest environments. Built for an extended lifespan this charger uses passive cooling to replace charger fans that commonly break with 4 aluminum fins that dissipate heat while providing enhanced shock proof and structural durability. Built for you. Built North Dakota tough.


We highly reccomend you use a LiFePO4 compatible charger. 12v chargers for lead acid batteries may work, but will decrease performance and lifespan of the battery.


INPUT 100-120VAC, 50/60HZ. OUTPUT: 14.4 volts, 40.0 amps, 10 amps per bank / channel


SAE connections make it easy to connect your charger to the battery. Install the ring terminals using the bolts on your terminals. Bolt black to your black terminal. Red to your red terminal. Do not short circuit. Then connect the charger via the SAE plug when you need to charge. Red light on the charger will turn on when charging. Light turns green when the battery is full.


Charger will restart or "wake up" a Dakota Lithium BMS that has turned off a battery due to short circuit or excessive amp draw. Simply connect the charger to the battery to initiate a restart.
