The Dutch company, Bellmarine, has designed and produced the first two Electric Seadoo GTElectric Waverunners in the world to be used especially aboard a brand new 80-meter superyacht, constructed by the renowned Dutch luxury yacht builder, Feadship.
Each Waverunner is equipped with a Liquid cooled 45kW 120V electric jet-propulsion system. This system is powered by a 120V/160Ah Lithium Ion Polymer battery pack.
The battery pack consits of 8 Lithium Ion battery modules all monitored with a special designed Battery Management System. The charging system is a 9kW charger for each Electric Waverunner and provided with an automatic Charger detecting system.
