World's second largest Maritime Battery Supplier.

Since 2009, EST-Floattech has developed and built intelligent energy storage systems and continues to contribute to clean, compact, safe and reliable source of energy. Before the company started as a maritime battery supplier, it was a system integrator in the marine market.

EST-Floattech is established as a merger between Floattech and ES Technologies. Floattech was a supplier of energy systems, navigation and communication equipment, computer networks, data links and multimedia products and CCTV for superyachts founded in 2004. ES Technologies was specialised in the design and supply of active battery management systems founded in 2009.

The company’s strong application and integration knowledge then paved the way to become one of the world’s strongest suppliers of energy storage systems (ESS). Learning from market developments to become a value-added battery provider, the company leveraged its experience and track record to optimally serve clients in today’s maritime industry, which started with the Green Orca-serie batteries and currently the company is working towards the DNV Type approval of the new Octopus-series.
