EV battery technology company Bewitch and electric boat propulsion company Sealance have entered into a memorandum of understanding to jointly develop a high-performance battery for jet boats.
Italy-based Sealence has developed an electric propulsion system called DeepSpeed (pictured above and below) that operates quietly and reduces vibration for watercraft ranging from fast tenders to large yachts.
DeepSpeed electric boat jets can deliver anywhere from 250 horsepower to 1,300 horsepower, and the company says the jets have superior fuel efficiency metrics compared to propeller-driven naval propulsion systems.
DeepSpeed requires battery performance similar to Enevate’s EV performance specifications: namely, high energy density with high discharge rates, long battery life, and extremely fast charging capability.

Enevate and Sealence engineers will work together in Southern California and Italy to first prove key battery performance metrics and then jointly develop a prototype.
Sealence Founder and CEO William Gobbo said:
The combination of Enevate’s silicon anode battery technology and Sealence’s revolutionary ultra-efficient DeepSpeed propulsion design can significantly accelerate the energy transition in many segments of the maritime mobility industry, with benefits economic for the operators and at the same time a positive impact for the environment with less pollution both in water and in the air.
Enevate, which was founded in 2005 at the University of California, licenses intellectual property and transfers technology to electric vehicle and battery manufacturers around the world. In February of this year, the company signed a lease for a facility in Irvine, Calif., of more than 125,000 square feet to expand its EV battery pre-production line. In February 2021, Enevate secured $81 million in Series E funding led by Fidelity.
