EST-Floattech Expands Octopus Series with Lithium Iron Phosphate Battery Modules

EST-Floattech, a Netherlands-based provider of energy storage systems for maritime and industrial applications, has expanded its Octopus Series with the launch of new Lithium Iron Phosphate (LFP) battery modules. The addition marks a strategic move to diversify the company’s offerings by addressing increasing market demand for alternative battery chemistries.

The newly developed Octopus LFP energy storage system (ESS) is designed for scalability and long-term performance in large-scale marine battery installations. The system integrates with the existing Octopus Series Battery Management System (BMS), which was developed in-house and is built on over 15 years of engineering experience. The BMS provides real-time diagnostics, precise power and thermal management, and ensures compliance with maritime class and cybersecurity standards.

Advancing LFP for Maritime Applications

The introduction of LFP chemistry reflects ongoing industry trends prioritizing safety, longevity, and cost-efficiency. The Octopus LFP modules feature a nominal voltage of 52V and a capacity of 233Ah. They are optimized for vessels with consistent discharge during the day and overnight charging cycles. The modules are configured in a flexible rack design—scalable in height and width—with integrated air ventilation to maintain thermal stability.

Unlike liquid-cooled systems, the air-cooled design offers reduced maintenance, eliminates the risk of leakage, and lowers system weight, making it a practical choice for marine environments.

Offering More Choice to the Maritime Sector

Mark Witjens, CEO of EST-Floattech, highlighted the importance of flexibility in energy storage solutions: “By introducing LFP to our Octopus Series, we empower shipbuilders and operators with greater choice. Different vessels have distinct energy profiles. LFP offers a robust and cost-effective solution for operations with high energy capacity requirements and extended charge-discharge cycles.”

Witjens also emphasized that the expansion aligns with growing demand for multiple battery chemistries across shipyards and fleets. “This development reinforces our commitment to delivering reliable, safe, and high-quality battery systems that meet the evolving needs of the maritime sector.”

Focus on Safety and Certification

Known for its “safe by design” approach, EST-Floattech’s Octopus Series has received type approvals from four major maritime classification societies. The company plans to achieve class certification for the new LFP modules by early next year, further ensuring the product’s suitability for global maritime deployment. With this addition, EST-Floattech continues to strengthen its position in the energy storage market by offering versatile, future-ready battery systems tailored to the operational needs of modern vessels.
