Helios Yachts focuses on creating affordable, sustainable electric boats that do not compromise on performance. Our commitment to innovation, community, and environmental stewardship sets us apart from the competition.

No service is included, but if you would experience any trouble with the software or other components of the boat, you can always turn to us and we will help you. If an accident was to happen, inflicting damage to the hardware, practically any repair shop will be able to fix it. If you have any questions regarding repairs, you can contact us, we are happy to help and recommend who you can turn to for service or repair.

Yes, our yachts are designed to perform well in a variety of environments, including coastal waters, lakes, rivers, and other inland waterways, offering versatility and reliability.

Yes, we offer customization options for many of our models, allowing you to choose features and finishes that match your preferences and needs.

Electric boats are environmentally friendly, more reliable, cheaper to operate and maintain, and dramatically better integrated digitally than conventional vessels. They allow you to enjoy the waters without the release of harmful emissions and other pollutants.

Helios boats are made to order. You can inquire about yours here.

Helios boats with solar panels charge automatically when the sun is available. All boats also include an industry-standard charging port (CCS1), allowing you to charge in all marinas and docks with electricity.

It varies from boat to boat, and it depends on charging infrastructure. The 240V available in most marinas will charge our boats overnight in most cases.

All our boats are using a “safe-to-touch” 48dc electrical architecture. Our battery packs and electrical systems are watertight, heavily reinforced and constantly monitored.

Other than standard cleaning and anti-fouling, Helios boats are practically maintenance-free.

We are firm believers that the chemistry in today’s LiFePo4 battery packs, generally intended to be used for Solar Storage, is the way forward for the marine industry. Being one of the safest battery technologies available today, it showcases perfect charge and discharge properties. A concern for reaching high temperature is highly unlikely as stability of the voltage is attained regardless of the SOC of the pack.

Our JAM (Just Add Module) plug-and-play allows you to expand the capacity and/or voltage so you have the flexibility to create and fit for your needs. Even more than that, our state-of-the-art software lets you configure your batteries bringing you the option for a bespoke solution.

We’ve seen LiFePo4 overcome a previous obstacle as well – the small energy density compared to other options which discarded the use of it for E-mobility. The density of the LiFePo4 today is already on par with other types of Li-Ion batteries keeping the advantages that give it edge – Safety and really SOL. A solid testimony being that the biggest automotive companies have started to integrate the strategy and create their EVs with LiFePo4.
