Power Supply Everyone is talking about electromobility – we are electronically mobile from the first day of development! Two powerful lithium-ion batteries in watertight housing guarantee that you can enjoy at least 1 hour on the water. If you do not constantly go full throttle, you can extend the pleasure even longer. The batteries are easy to replace like a drawer. To enjoy the time on the water for longer, just buy another set of batteries.Each battery comes with a charger, so you can easily charge it overnight.
