Dovetail Chooses Mobius.energy to Supply Batteries for Electric Conversion of Commuter Aircraft

Dovetail Electric Aviation is to incorporate Mobius.energy Corporation’s Husky battery module to power a total of 65 of its electric conversions of Cessna Grand Caravan and other commuter aircraft.

Dovetail plans to bring converted battery electric commuters to market as fully certified aircraft by 2025 and Mobius will support Dovetail’s efforts with a certifiable battery solution.

The conversion of turbine aircraft to electric propulsion promises to bring zero-emission aviation into the mainstream much faster and more cost-effectively than via newly commissioned electrical planes.

Dovetail expects to achieve a Supplemental Type Certificate (STC) for converted aircraft within three years, compared with more than eight to ten years for clean sheet electric aircraft, and at a fraction of the certification costs, and the converted aircraft will be quieter and enjoy reduced operating costs of around 40%.

The company has established customer relationships with a range of airlines including Australia’s Sydney Seaplanes, Alt Air, SeaAir Pacific, Europe’s Volotea, Air Nostrum, Isla Air, and Monte Aircraft Leasing. It has also recently announced Rex Airlines, the largest regional airline operator in Australia, as a strategic partner.

Dovetail CEO and co-founder David Doral said: “Mobius’s battery module supports our efforts to reduce the operating cost of regional air service operation by over 40 percent, and we are excited to be the fixed-wing aircraft launch partner for it.”

At 800V, the Husky’s modular architecture includes an innovative thermal management system and a customisable battery management system. Multiple modules can be connected in parallel to build a pack to power an aircraft and to provide redundancy for improved safety.

The modular approach radically simplifies battery pack installation, maintenance, and removal. With only 20% of the non-cell component overhead, Mobius’s industry-leading lightweight design results in a high energy density of 216 Wh/kg at the pack level using market-proven Li-ion battery cells.

Mobius CEO and founder Eugene Choi said: “We are absolutely thrilled to partner with Dovetail to supply batteries for electric conversion of its commuter aircraft. Dovetail and Mobius are well aligned to bring zero emissions aviation to the mainstream, with the best technology solutions available now while making provisions for future innovation.”
