Marine
The Perfect Hull Deserves
a Purpose-Built Powertrain.
In the marine industry, performance is everything. Off-the-shelf batteries force you to compromise on your vessel's design, impacting everything from hull dynamics and interior space to on-water performance. IONETIC provides a new path forward: a fully bespoke battery system, engineered to be the heart of your vessel, delivered on a capital-efficient and accelerated timeline.
Custom battery packs for BEVs and plug-in hybrids, brought to market faster and more cost-effectively.
Engineered for the Hull, Not the Shelf.
An off-the-shelf battery dictates your layout; a bespoke one serves it. We solve your toughest packaging challenges by engineering a battery that integrates perfectly with your system design, enabling a lower centre of gravity, superior handling, and more usable space for your customers.
Performance, Without the Bespoke NRE.
Launching a custom marine battery program shouldn't require a prohibitive R&D budget. By adapting our pre-validated architectures, we provide a capital-efficient path to a bespoke solution, drastically reducing your development costs and financial risk.
Accelerate Your Time-to-Water.
In a competitive market, getting your new model on the water first is a critical advantage. Our integrated design and manufacturing process transforms a multi-year project into a matter of months, getting your prototype built and ready for on-water testing faster than the competition.
Our Platform Capabilities
The demands of the marine market are unique, requiring a platform built for versatility, reliability, and power in a harsh environment. Our dual-architecture approach provides this, whether it’s the ultimate space-efficiency of a 'blade' pack structurally integrated into a hull, or the supply chain and chemistry flexibility of our 2170 cylindrical format. This strategy allows you to develop an entire range of vessels, from high-performance tenders to long-range cruisers. on a common, validated foundation, drastically reducing your development costs and simplifying your supply chain across your entire product portfolio.

High Performance Marine.
- Deliver a thrilling, best-in-class experience with the extreme, continuous power needed for rapid acceleration and holding high speeds.
- Achieve superior dynamics and design freedom with a compact, lightweight pack that enables a lower centre of gravity and sharper handling.
- Ensure reliable and repeatable peak performance with an advanced thermal management system engineered for the harsh demands of the marine environment.
High Energy Density Marine.
- Maximise your vessel's operational range and reduce charging frequency by engineering a powertrain with the highest possible energy density.
- Enhance on-board luxury and comfort by freeing up valuable internal volume for more spacious cabins and amenities.
- Provide silent, uninterrupted, emission-free power for all on-board loads, eliminating the need for a noisy generator at anchor.
Powering a High-Performance Marine Platform
For a manufacturer developing a new electric powertrain platform for high-performance marine applications, the battery was the most critical system. They needed a solution that could deliver extreme, continuous power while also being versatile enough to serve as a modular building block for a wide range of future vessels, from high-speed day boats to luxury tenders.
The Challenge
The project presented a unique set of competing demands. The customer’s primary challenge was to develop a single, optimised battery pack that could be used across multiple, diverse marine applications. This required a delicate balance of dimensions, energy, power, and cost in one universal unit. Furthermore, the battery had to deliver class-leading, continuous power.
The Solution
IONETIC engineered a highly optimised battery pack that served as the versatile heart of the customer’s new electrification platform. Leveraging our proprietary software and rigorous in-house cell testing, we evaluated multiple cell options to find one capable of delivering a market-leading continuous discharge rate, while maintaining target unit costs. The pack's energy and dimensions were carefully optimised so that it could function effectively as a single unit for smaller vessels, or be connected in parallel to create a larger array for more demanding applications. This gave the customer a single, powerful, and scalable building block to power their entire portfolio, drastically simplifying their supply chain and accelerating their time-to-market.
Designed around your requirements.
Every battery pack we create starts with your exact performance, cost, and integration needs. Using our scalable design system, we engineer packs specifically for your application, rather than forcing you into off-the-shelf constraints. This allows us to make the right trade-offs between power, energy density, chemistry, form factor, and lifetime to deliver a pack that truly fits your product.
Safety and validation built in.
By working with IONETIC, your battery benefits from existing, validated design systems. By leveraging prior validation work, we reduce certification complexity, de-risk compliance, and help ensure your battery meets the highest expectations for performance, reliability, and safety.
Faster time to market.
Our platform approach can cut up to two years from traditional battery development timelines. By building on proven architectures, validated subsystems, and automated design tools, we dramatically reduce engineering cycles and iteration time. That means you can move from concept to production faster — helping you launch sooner, capture market opportunities, and reduce development risk.
European manufacture.
With manufacturing based in Europe, we offer a trusted, local supply partner with clear communication and greater transparency. Shorter supply chains mean faster lead times, improved responsiveness, and better collaboration throughout development and production. For customers who value reliability, speed, and close working relationships, our European footprint delivers a meaningful operational advantage.
