48V Marine Battery with the Highest Levels of Safety & Performance

Epsilor Electric Fuel Ltd., a world recognized developer and manufacturer of smart Li-Ion batteries and chargers, has completed the rigorous safety certification process of its highest-voltage 48V and 24V marine batteries specialized for luxury and racing boats. Electric Fuel's 48V, 24V, and 12V marine grade batteries have the highest energy and power density of any Li-Ion battery in the market and will be presented at Metstrade 2025 (November 18 – 20, Booth 402, Hall 2).

"Electric Fuel's 48V batteries provide the high energy and power we need to succeed in racing boat competitions," said Marco Donati, founder at Donati Racing. "The lightweight, high-energy density battery saves weight and space which are critical elements for boats, particularly racing boats."

Rugged and ultra-durable, designed by defense battery specialists familiar with military-grade testing, this civilian, marine battery has proven experience supplying full power and energy performance under the most severe conditions. Electric Fuel's marine batteries serve hundreds of racing boats in top global competitions with extreme power and energy needs. Throughout the races, the batteries faced constant exposure to corrosive seawater, frequent in-motion transfers, and numerous charges each day. Despite these demanding conditions, the batteries maintained maximum levels of performance. 

"Certified safe Li-Ion 48V marine batteries are the future," said Ronen Badichi, President and General Manager of Epsilor Electric Fuel. "Luxury yachts and racing boats are the natural early adopters, looking to preserve expensive vessels and invaluable human life while maximizing performance. 48V marine batteries will soon dominate the industry."

Electric Fuel's 48V marine battery provides maximum efficiency, range, and now proven, certified safety. The higher voltage efficiently powers more powerful and higher voltage motors while generating less current and less heat, enabling the use of thinner, lighter cables. Larger yachts benefit from reduced voltage drop over long cable runs while racing boats benefit from the reduced weight. 

Electric Fuel's new certified Li-Ion 48V marine battery is a gamechanger in the electric boat industry, creating a new standard for safety and performance. This marine battery surpasses all safety and environmental standards in the industry with its IEC62133 certification, creating a new threshold for high-end, high-performance batteries for electric boats. 

IEC-62133 Compliance
IEC-62133 is the golden standard for testing the safety of portable batteries. 

To qualify for IEC-62133 certification, Electric Fuel's 48V and 24V batteries were evaluated on their ability to withstand: free falls (drops), overcharging, mechanical vibration, mechanical shock, external short-circuiting, and stress on the battery case.
