How It Works
When the battery drops below the preset threshold, the range extender starts automatically. Its built-in generator converts fuel energy into electricity, supplying it in real time to the battery pack and electric motor. The vessel maintains electric propulsion throughout, with the RE Series ensuring consistent energy support.
