About NautiFlux

The global leisure marine industry is in the midst of a transformative shift toward electrification. Today's boat builders and yacht owners are increasingly demanding a new kind of on-water experience: one that is zero-emission, whisper-quiet, low-maintenance, and designed for uncompromised comfort, whether cruising the Mediterranean's azure coasts, island-hopping in the Caribbean, or spending a day fishing or watersports on local inland and coastal waters. For decades, traditional combustion engines have defined the leisure marine experience—but they come with inherent tradeoffs: intrusive noise and vibration that disrupt time on the water, harmful exhaust emissions that damage fragile marine ecosystems, and costly, time-consuming maintenance that takes owners away from the joy of boating. Meanwhile, many existing marine energy storage solutions on the market are repurposed from commercial shipping applications, built for large cargo vessels rather than the unique needs of leisure craft. These one-size-fits-all systems fail to balance the lightweight, space-efficient, easy-to-install needs of small to mid-sized recreational boats, with the bespoke integration, premium comfort, and silent operation demanded by luxury yacht owners.

That's why NautiFlux was built. We are a global, leisure marine-exclusive energy storage technology brand, dedicated to designing and manufacturing purpose-built marine battery packs and full-vessel electrification solutions for the two core segments of the leisure boating market: small to mid-sized recreational vessels and luxury yachts. We're redefining the electric boating experience, making zero-emission sailing accessible, reliable, and premium for builders and owners across the world. Our solutions are fully tailored for day cruisers, sport boats, fishing vessels, luxury yachts and more, with full alignment to the requirements of leading international classification societies including DNV, ABS, and LR. Backed by a localized service network across the world's premier yachting hubs, we provide end-to-end dedicated support for boat builders and yacht owners, from initial concept design and installation to commissioning and ongoing maintenance.

Vision & Mission

Pioneering Marine Energy

Empowering Through Technology — Intelligent & Seamless — Extraordinary Experience

We believe that technology delivers an intelligent, non-sensory and extraordinary experience. We are committed to enabling customers to achieve transformative advancement in energy utilization and intelligent experience through pioneering technological innovation.

For the global leisure marine sector, this means we engineer every solution to redefine the on-water experience: we embed aerospace-grade safety standards, automotive-grade intelligent control, and marine-specific engineering into every battery system we build, to deliver zero-compromise electrification that is inherently safe, seamlessly intelligent, and effortlessly premium.

Our Solutions

01

Marine-Exclusive BMS

Our marine-exclusive Battery Management System (BMS) is tailored to the intermittent charge and discharge cycles of leisure boating, delivering intelligent energy distribution across the entire vessel, from propulsion to onboard amenities, with precise state-of-charge monitoring and health management over the full system lifespan. We embed aerospace-grade safety standards, automotive-grade intelligent control, and marine-specific engineering into every system we build.

02

Thermal Protection

Our multi-layer thermal runaway protection system is built to aerospace-grade safety standards, creating a fully closed-loop safety barrier with early warning, active prevention, and passive containment to eliminate fire risk at the source, even in the most extreme scenarios.

03

Smart Energy Platform

Our fully integrated smart marine energy management platform seamlessly connects with a vessel's onboard control systems, infotainment, house loads, and propulsion, giving owners simple, single-screen control of their vessel's entire energy ecosystem, delivering the intelligent, non-sensory experience at the core of our vision.

Our Product Lines

Automotive Power System

Luxury Yacht Series

Custom-built for 50 to 100ft luxury yachts, featuring a highly integrated modular design that delivers ultra-quiet operation, a compact footprint, and exceptional cycle life. The system seamlessly integrates with both the yacht's electric propulsion system and full onboard house loads, delivering consistent, reliable power for long-distance bluewater cruising.

Marine Power System

Recreational Series

Purpose-built for 10 to 40ft small to mid-sized recreational boats, including day cruisers, sport boats, fishing vessels, and inland sightseeing craft. The system features a lightweight, all-in-one design with a compact footprint, simple installation, and easy maintenance, perfectly suited to the limited space available on smaller vessels.

Global Compliance

Certified Excellence

All our products are designed, tested, and manufactured in full alignment with the International Maritime Organization (IMO) regulations for recreational vessels, with ongoing certification for leading international classification societies including DNV, ABS, and LR. This ensures our systems are fully compliant and ready for operation in all the world's premier yachting destinations.

Every system undergoes rigorous testing across extreme temperature ranges, high humidity environments, salt spray exposure, and mechanical shock and vibration, to ensure they perform flawlessly across all conditions, from tropical waters to northern seas.
