The safety and comfort of maritime travel depend on a stable and reliable power supply. Whether it's navigation and communication on small fishing boats, living amenities on luxury yachts, or emergency systems on operational vessels, the long-lasting range of a 12.8V marine lithium battery directly determines the quality of the voyage. The marine environment's high salt spray, high humidity, strong vibrations, and susceptibility to water splashes make ordinary chargers highly susceptible to corrosion and damage. The core requirements for marine chargers are "deep-sea level waterproofing, salt and corrosion resistance, precise compatibility, and safe durability." We have specially designed a 12.8V marine battery-specific waterproof charger for you—breaking through the constraints of the marine environment with IP67 protection, and safeguarding your navigational power to marine standards, ensuring every voyage is fully powered and worry-free.

　　Born for the seas, designed for waterproofing and corrosion resistance

　　IP67 deep-sea waterproof rating, fearless of seawater: Utilizing a fully sealed potting process and stainless steel waterproof interfaces, it achieves the highest IP67 protection level, capable of withstanding immersion in 1 meter of water for 30 minutes, completely resisting seawater splashes, heavy rain, and deck flooding. The outer shell undergoes a special anti-salt spray coating treatment, passing a 500-hour salt spray corrosion test, ensuring no rust even after long-term use in high-humidity marine environments, completely solving the corrosion problem of ordinary chargers.

　　12.8V precise compatibility, suitable for all marine batteries: Designed specifically for 12.8V marine lithium iron phosphate/ternary lithium batteries, perfectly compatible with mainstream deep-cycle battery capacities of 20-250Ah, compatible with various marine 12.8V devices such as fishing boat starting batteries, yacht energy storage batteries, and marine emergency power supplies. The charging cut-off voltage precisely matches the 14.4V standard, avoiding battery bulging and capacity degradation caused by voltage deviation, extending the lifespan of deep-cycle batteries.

　　Four-stage intelligent charging for efficient and time-saving replenishment: Equipped with marine-customized four-stage charging technology, parameters are dynamically optimized for marine lithium battery characteristics: When deeply discharged, trickle pre-charge protects the battery; after voltage recovery, it switches to constant current fast charging, reaching 60% charge in 30 minutes; near full charge, it switches to constant voltage replenishment; finally, single-cell balancing ensures battery pack consistency and increases cycle life by over 30%; the charging conversion rate reaches 94%, saving 10% power loss compared to traditional marine chargers; a full charge can be achieved in 2.5-4 hours, meeting the need for rapid replenishment during voyages.

　　Marine-grade certified for safety, ensuring worry-free navigation: Type approved by the China Classification Society (CCS), compatible with international marine standards such as DNV and BV, and compliant with the IEC 60945 marine electrical equipment safety standard; features six built-in protection systems: overcharge, overtemperature, short circuit, reverse connection, overload, and surge protection; equipped with NTC temperature monitoring, automatically suspending charging when the battery temperature exceeds the safe range of -25℃ to 60℃; its shock-resistant structural design withstands severe vibrations during ship navigation, ensuring stable operation in rough seas and protecting the ship's electrical safety.

　　Marine-grade durability, suitable for complex environments: The outer shell is made of marine-grade aluminum alloy, impact-resistant and corrosion-resistant, and has passed a 1.5-meter drop test; operating temperature range is -25℃ to 60℃, suitable for extreme scenarios such as high-temperature decks and low-temperature navigation in the open sea; supports a wide voltage input of 90-264Vac, compatible with three power supply modes: dock mains power, shipborne generator, and solar panels, allowing for flexible power replenishment while anchored, at sea, or docked.

　　Suitable for Diverse Maritime Scenarios

　　**Fishing Vessel Power Supply:** Provides continuous power to fishing finders, navigation systems, walkie-talkies, and fishing equipment. IP67 waterproof design withstands seawater splashes from the deck, and the anti-salt spray coating adapts to the high humidity environment at sea, ensuring stable power for near-shore or deep-sea fishing operations.

　　**Yacht Living Power Supply:** Charges yacht air conditioners, refrigerators, audio-visual equipment, and lighting systems. Four-stage balanced charging technology ensures long battery life. Combined with solar panel charging, it allows for simultaneous charging and navigation, creating a comfortable mobile home at sea.

　　**Ship Emergency Backup:** Serves as a dedicated charger for ship emergency power. Rapid charging ensures the continuous operation of navigation equipment, communication radios, emergency lighting, and lifesaving equipment, providing a strong safety barrier in the event of sudden power outages or extreme weather.

　　**Dock Centralized Power Supply:** Supports simultaneous charging of multiple devices (dual-interface design), adapting to dock centralized power supply scenarios and meeting the batch charging needs of small fleets. Its high efficiency and energy saving characteristics reduce long-term operating costs.
