Maritim & Offshore Battery Solutions

Full power ahead in all weathers

Reliable, safe and high-performance energy supply is of great importance in professional shipping as well as in the private use of electric motor boats and yachts. Our batteries meet the demanding and sometimes harsh conditions on the water down to the last detail. This is also confirmed by the DNV-GL. The maritime classification society certifies aentron GmbH in the areas of shipping, offshore installations, speedboats and light boats. With the DNV-GL certification, aentron is one of the few manufacturers worldwide to offer HV lithium-ion batteries with DNV-GL Type Approval Certificate (TAE00003BY).

In order to glide across the water at full power, electric-powered boats need reliable and powerful propulsion solutions. aentron produces durable high-voltage and low-voltage battery solutions, even for harsh sea conditions. aentron’s maritime battery systems are modular and can be flexibly adapted to the respective requirements.


aentron battery systems are ideal for demanding use on the water: Our battery systems can easily withstand dust, dirt, extreme weather conditions and large mechanical loads. The batteries from aentron are also characterized on the high seas by their high energy density, robust design, energy management and power configuration and can be easily integrated into existing systems thanks to the “Plug & Sail” system.

Efficiency & Emission

More than 80 percent of the global cargo is transported by ship. But also in passenger shipping and in the field of private yachts and motoboats there is great potential for the protection of the environment and climate. This is why electric drive solutions and hybrid drives are becoming increasingly important in the field of shipping, precisely because even with electric drive solutions, even higher speeds and ranges can be achieved.




HANKE & DORSCH specializes in the production of innovative light-running electric boats that reach high speeds despite low motorization. The electric boats are industrially produced under the brand my-electroboat.com in their own production in Germany. Custom-made products are no problem either – HANKE & DORSCH supplies a wide range of high-performance, reliable and individually designed electric motor boats.


In order to be able to glide across the water at full power, HANKE & DORSCH electric boats require a reliable and powerful drive. aentron’s batteries are innovative power storage systems with lithium-ion cells that are configured to be tailored for the respective electric boats. aentron battery systems are ideal for demanding use on the water: they can withstand dust, dirt, extreme weather conditions and large mechanical loads without any problems.
