Protected with IP67
Our consumer batteries with IP67 protection class can withstand any challenge: thanks to state-of-the-art membrane technology, they are not only protected against dust and dirt—they can even withstand splashes and jets of water with ease. Even temporary submersion? No problem!
Extreme cold?
No problem with Arctic technology!
Experience unlimited freedom – even in freezing temperatures down to –30 °C! Our LiFePO4 batteries with innovative Arctic technology continue to run reliably, while conventional lithium batteries stop working at temperatures as low as 0 °C. The secret: two energy-efficient heating elements, controlled fully automatically by the battery management system, keep the cell temperature above freezing at all times. Perfect for demanding trips in cooler waters – on motorboats, sailboats, or yachts. Thanks to flexible installation options, they can also be used in unheated areas below deck without any problems. Best of all, Arctic technology can be easily retrofitted to all LX models from 100Ah upwards. With Arctic, you are always well prepared – no matter how cold it gets!
Proven reliability for extreme conditions – GORE® Vent
Our batteries with integrated GORE® PolyVent offer a decisive advantage over conventional batteries. Thanks to the unique GORE membrane made of 100% ePTFE, the housing is optimally protected against water ingress. The intelligent bidirectional air exchange enables efficient pressure equalization and prevents mechanical stress on seals and housing. At the same time, it effectively reduces condensation inside the battery, which often causes damage in conventional batteries. In the event of temperature fluctuations, PolyVent ensures reliable temperature equalization and protects against thermal stress. With GORE® PolyVent, we rely on proven technology for maximum reliability and durability.
EKOcast – Die intelligente Steuerungszentrale für Ihre Yacht
EKOcast macht Ihre LIONTRON® LiFePO4-Batterie zur volldigitalen Versorgerlösung an Bord. Das smarte Kommunikations- und Sicherheitssystem erweitert nicht nur die Funktionen Ihrer Lithium-Eisenphosphat-Batterie, sondern schützt sie auch zuverlässig vor unbefugten Zugriffen. Die nahtlose Integration in bestehende Stromversorgungssysteme wie Victron-Anlagen, individuelle Steuerungen oder Displays macht EKOcast zur perfekten Lösung für Motorboote, Segelyachten und Katamarane.
Mit der LIONFlash App spielen Sie die Software direkt auf Ihre Batterie auf – schnell und unkompliziert. Verbinden Sie beliebig viele Displays und Endgeräte gleichzeitig und profitieren Sie von Fernwartung und Softwareupdates direkt über Ihr Smartphone oder Tablet.
Überwachen Sie bis zu 10 Batterien bequem über Bluetooth in der LIONTRON® Multi App – oder greifen Sie vom Landsteg oder von überall auf der Welt über das Internet zu, beispielsweise über das VRM-Portal von Victron. LIONTRON® stellt den passenden Treiber bereit und sorgt so für maximale Flexibilität und Kontrolle – egal ob Sie an Bord oder auf Landgang sind.
Modular. Sustainable. Future-proof.
Put an end to the throwaway mentality! Our LIONTRON® LiFePO4 batteries set new standards in terms of sustainability and cost-effectiveness. The secret: a consistently modular design that makes servicing easier than ever before.
Your safety is our priority: If a single cell fails, the battery power is partially maintained—unlike conventional systems, which shut down completely immediately. This allows you to bring your boat safely into port, where you can replace the defective component at your leisure. Maximum operational safety when it matters most.
Forget about glued housings and welded components. Our batteries can be opened in seconds—just loosen four screws, and you’re done. All components, such as cells, battery management system (BMS), or Bluetooth module, are screwed together instead of soldered and can be replaced individually if necessary. In the event of a malfunction or technical questions, our competent service team is there for you—contact us and we will find a solution together.
Why dispose of an entire battery when only one component is defective? We preserve everything that is still functional. This not only conserves valuable resources, but also saves you money. Repairs are inexpensive and extend the life of your battery well beyond the warranty period.
Our promise to you: Every spare part will remain available for at least another 10 years after production has been discontinued. This ensures cost-effective repairs and maximum longevity—far beyond the already generous 10-year manufacturer’s warranty.
Invest in quality that lasts. With LIONTRON®, you can rely on batteries that can be repaired instead of replaced – for a sustainable and economical energy supply.
*The 7-year warranty continues to apply to batteries purchased between January 1, 2023, and August 31, 2024.
