Product Description
Built for rugged reliability on and off the water, the Marine 4 is a 4 bank battery charger engineered exclusively for 12V lithium batteries. With 4 banks charging at 10 amps per channel, you can rapidly charge up to 4 lithium batteries including marine, boat, starter, and deep-cycle batteries. This onboard battery 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 onboard boat battery charger is double sealed. Fully-sealed and waterproof 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 with 4 aluminum fins that dissipate heat while providing enhanced shock proof and structural durability.
Common Applications:
- Onboard Marine Battery Charger
- Charging up to Four 12V Batteries Simultaneously
- Optimal for Batteries >20 Amp Hours
- Onboard Charging for Boats, RV’s and Golf Carts
- LiFePO4 Compatible Charger
- Lithium Titinate Oxide (LTO) Compatible Battery Charger
A LiFePO4 battery charger like this one is necesary for lithium batteries for proper battery operation and overall lifespan.
Input - 100-120VAC, 50/60HZ
SAE connections make it easy to connect/disconnect your charger from the batteries. Install the ring terminals using the bolts on your terminals, 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. Do not short circuit charge leads.
Charger will restart or "wake up" a Dakota Lithium battery BMS that has turned off a battery due to short circuit, excessive amp draw or complete discharge. Simply connect the charger to the battery to initiate a restart.
Charging status LED's for each bank. Red = Charging / Green = Charge Complete
Charges at a rate of 10 amps per battery (up to 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 (Ah) battery would charge in 5.4 hours.
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 our laboratory testing we found that the longest lifespan for Dakota Lithium batteries was at a charging speed of 0.3C or less (we recommend that the charger amp rating is 1/3 or less of the battery amp hour rating for longest lifespan).
14.4 volts is recommended for Dakota Lithium batteries. This charger charges at 14.4 volts.
