Marine 4 Bank, 40-Amp (10-Amp Per Bank) 12V Onboard Lithium Battery Charger

The Marine 4 Bank, 40-Amp (10-Amp Per Bank) 12V Onboard Lithium Battery Charger is specifically engineered to charge 12V lithium batteries rapidly and reliably, making it ideal for marine, boat, RV, and golf cart applications. With 4 independent charging channels, it can simultaneously charge up to four 12V lithium batteries, ensuring each battery is fully charged and balanced for maximum performance and lifespan.

Key Features:

High-Efficiency, Multi-Bank Charging

• 4 Independent Charging Banks: Each bank charges at 10 amps, enabling you to charge up to 4 batteries at once. This allows for rapid charging of multiple batteries in parallel or series configurations, perfect for applications like trolling motors or RV power systems.
• Quick Charging Speed: For example, a 54Ah battery will fully charge in about 5.4 hours when using the 10 amp per bank charge rate.

Built for Harsh Environments

• Waterproof Design (IP67 Rated): This charger is sealed to withstand water, dust, and extreme environments. Whether on a boat or in harsh weather, it will continue charging without fail.
• Rugged Aluminum Case: The charger is housed in a shockproof, high-tensile aluminum case, ensuring it remains durable and operational in rough conditions.
• Passive Cooling System: No need for fragile cooling fans—this charger utilizes 4 aluminum cooling fins to dissipate heat, ensuring longevity and reducing potential damage from overheating.

Battery Management System (BMS) Communication

• Smart BMS Communication: The charger will restart or "wake up" any Dakota Lithium BMS that has turned off the battery due to short circuits or excessive amp draw. Just connect the charger, and it will restore power automatically.

Ease of Use

• SAE Terminal Connections: The charger uses SAE connections for easy setup. Simply attach the ring terminals to your battery’s posts and connect via the SAE plug when charging.
• Indicator Lights: The charger’s red light indicates charging is in progress, while the green light signals when charging is complete.

Versatile Charging for Various Battery Configurations

• Adapters Available: If you need to charge 24V, 36V, or 48V single batteries or mixed battery banks, you can request an adapter (at no additional cost) to expand your charging capabilities.
