Core Competitive Advantage (Designed for Yachts, High Safety and Compatibility)
1. IP67 top-level protection, suitable for all water conditions of yachts
The integrated sealed die-cast aluminum housing + military-grade waterproof sealing ring is used to achieve IP67 waterproof and dustproof level, which can withstand the splashing of waves during yacht navigation, deck water immersion, and even short-term immersion in water 1 meter deep without leakage; the surface of the housing is treated with anodizing anti-salt fog process to effectively resist sea salt fog and high humidity corrosion, solving the core pain points of easy water ingress and corrosion in ordinary battery yachts, and suitable for various navigation scenarios in near-sea and far-sea.
2. Lithium iron phosphate original high safety, multiple protection zero risk
The battery cell uses grade A lithium iron phosphate, without cobalt or heavy metals, and does not catch fire or explode even in overcharging, over-discharging, puncture, or compression; an intelligent BMS for yachts is built-in, achieving 7-level safety protection for overcharging, over-discharging, short circuit, over-temperature, over-current, cell balancing, and reverse connection protection, and also compatible with voltage fluctuations during idle and high-speed navigation of yachts, ensuring the stable operation of the power system, even in extreme conditions, it can safeguard the yacht's power supply safety.
3. Lightweight and high energy efficiency, saving yacht space and enhancing range
Compared with the same energy lead-acid marine batteries, the weight is reduced by more than 60% (the same energy lead-acid battery is about 70kg, while this model is only 28kg), the volume is reduced by 50%, and it can be flexibly installed in the narrow battery compartment of yachts, significantly saving the storage and layout space of yachts; the energy density reaches 120Wh/kg, the charging and discharging efficiency is ≥95%, one charge can support the continuous operation of yacht life electricity (refrigerator, air conditioner, audio-visual, lighting) for 8-10 hours, or assist the propulsion system for short-distance navigation, without memory effect, it can be charged as needed, improving yacht range and usage experience.
4. Long lifespan and low maintenance, cost reduction throughout the life cycle
The cycle life is ≥6000 times (80% DOD), which is 8-10 times that of ordinary lead-acid marine batteries, normal use can last up to 8-10 years, significantly reducing the frequency of yacht battery replacement; the full maintenance-free design requires no liquid replenishment, no balanced charging, no electrolyte leakage, no harmful gas emissions, avoiding corrosion of equipment inside the yacht cabin, reducing the workload of crew maintenance, and saving usage costs for yacht end customers from the entire life cycle.
5. Standardized compatibility, seamless integration with yacht power system
The voltage and current are perfectly compatible with the mainstream propulsion systems, control systems, and charging systems of mid-to-high-end yachts, supporting constant voltage charging, solar power supplementation, and other charging methods, it can directly replace the original lead-acid batteries without additional line modification; it supports CAN bus / RS485 communication, can be connected to the yacht's control screen, real-time display of battery voltage, current, remaining power, and cycle times, achieving intelligent monitoring, suitable for the upgrade needs of yacht intelligence.
