EST-Floattech expands Octopus Series battery system with LFP battery module
EST-Floattech, a Dutch energy storage systems provider, has expanded its Octopus Series battery system portfolio with the introduction of new Lithium Iron Phosphate (LFP) battery modules.
This latest addition caters to the market’s demand for diverse battery chemistries and is designed for robust, large-scale battery systems.
The new LFP battery modules offer enhanced energy density and cost-effectiveness per kilowatt-hours (kWh), in addition to better thermal stability, extended lifecycle, and improved safety, making them suitable for vessels that discharge during the day and charge overnight.
The technology will provide shipowners with more options to meet specific application needs, extend battery life, improve fleet sustainability, or implement systems adhering to stringent safety standards.
Each module features a nominal voltage of 52V and a capacity of 233Ah, allowing for scalable integration into larger battery systems of multiple megawatt-hours (MWh).
The modular rack design of the modules is adaptable in both height and width, incorporating integrated ventilation for optimal thermal management.
The air-cooled system presents advantages over liquid cooling by eliminating leakage risks, reducing maintenance, and limiting weight.
EST-Floattech CEO Mark Witjens said: “By introducing LFP to our Octopus Series, we empower shipbuilders and operators with even more choice. We understand that different vessels have different energy profiles.
“LFP gives us the ability to serve applications with a high energy capacity demand and long discharge and charge cycles with a robust, safe, and cost-effective solution—without compromising on our commitment to reliability and quality. The development of LFP is the logical step for EST-Floattech to cater the growing demand for different chemistries by shipyards and shipowners.”
The LFP modules will be fully integrated with the in-house developed Octopus Series Battery Management System (BMS), which ensures precise thermal and power management, real-time diagnostics, and compliance with maritime classification and cybersecurity standards.
The Octopus Series has type approvals from four major maritime class approvals. EST-Floattech aims to have the LFP module certified by various class societies at the beginning of next year.
EST-Floattech technical director Diederick Stam said: “Our engineers have qualified the new LFP modules to meet the same high standards we apply across the Octopus Series.
“This addition enhances our ability to support even more vessel designs and hybrid propulsion systems, enabling cleaner and smarter shipping. During the entire development process, we’ve continuously adhered to our safe by design mentality.”
