The Dakota Lithium Marine 4 Bank 12V Onboard Charger is a rugged, premium option for users utilizing multiple 12V batteries in series, such as in boats, golf carts, RVs, and more. Its design and engineering behind it were exclusively done for lithium batteries, with the ability to charge 10 amps per bank/channel concurrently. This means that up to four batteries can be efficiently charged at the same time, improving the overall maximum performance and lifespan of all your batteries. The charger itself double sealed and enclosed in a shockproof aluminum casing. It is rated at IP67 protection, ready to withstand the coldest and wettest environments thrown at it. A passive cooling system replaces the common charger fan design, enhancing shock resistance and overall structural durability to ensure a much longer lifespan.

FOR 12 VOLT LITHIUM BATTERIES

It is highly recommended you use a LiFePO4 compatible charger. 12V chargers for lead acid batteries may work, but will decrease performance and lifespan of the battery.

CHARGER RATING

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

TERMINAL CONNECTIONS

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.

SMART BMS COMMUNICATION

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.

HOW FAST WILL MY BATTERY CHARGE?

Charges at a rate of 10 amps per battery (4 batteries supported). To determine your charging speed take the amp hour rating of your battery and divide by 10. For example, a 54 amp hour battery (Ah) would charge in 5.4 hours.

CAN I CHARGE MY BATTERY FASTER?

For most applications a charging time of 3 – 10 hours provides the longest lifespan for your battery. But if you have an application where you need rapid charging Dakota Lithium batteries can be safely charged in up to 1 hour (at a rate of 1C). For example, you could use a 20 amp charger with a 23 Ah battery for a 1 hour charge time. Charging at a 1 hour rate does reduce the lifespan over time. In laboratory testing it was found that the longest lifespan for Dakota Lithium batteries was at a charging speed of 0.3C or less (it is recommended that the charger amp rating is 1/3 or less of the battery amp hour rating for longest lifespan).

WHAT VOLTAGE SHOULD LIFEPO4 BATTERIES BE CHARGED AT?

14.4 volts is recommended for Dakota Lithium (LiFePO4) batteries. This charger charges at 14.4 volts.

WATERPROOF

Built for marine use. IP67 Rating . Internal components are sealed in a waterproof putty that makes it impossible for water to short circuit the charger. Wiring is SAE waterproof plugs.
