magniX Samson Batteries Power First Flight of Bye Aerospace eFlyer 2

Friday 25th September 2026

magniX, the company powering the electric age, today announced that its Samson batteries have been used for the first flight of Bye Aerospace’s eFlyer 2 prototype. The eFlyer 2 took off from Centennial Airport near Denver, Colorado, marking a significant milestone in the program.

This was the first flight to be powered by magniX’s Samson300 battery product. The Samson300 offers industry-leading energy density of 300 Wh/kg, unmatched cycle life of over 1,000 full-depth discharge cycles, and patented safety technologies. Samson batteries can be integrated into aircraft as part of a full magniX powertrain and are available as a standalone product. Delivering up to 800 volts, magniX batteries have been designed to meet the demands of mission-critical applications across a range of industries in aerospace and beyond, including data centers, energy storage, mobility, and defense.

Bye Aerospace’s eFlyer 2 is forecast to cost significantly less to operate than legacy piston training aircraft, is designed for rapid charging, and will produce zero emissions. This technology will disrupt the flight training market, where rising costs have contributed to a critical pilot shortage facing the global aviation industry.

Samson Batteries Lead on Performance and Reliability

“The first flight powered by magniX’s Samson battery product is a major milestone, demonstrating the exceptional performance of our technology,” said Reed Macdonald, CEO of magniX. “I would like to congratulate the team at Bye, who are doing important work applying the low-cost of operation and increased reliability of electric aircraft to the flight training market.”

“The successful first flight of the eFlyer 2 marks a major milestone for Bye Aerospace and demonstrates the progress being made across the electric aviation industry,” said Rod Zastrow, CEO of Bye Aerospace. “We're proud to have achieved this milestone with magniX's Samson battery technology onboard. We look forward to continuing our work together as we expand the eFlyer 2 flight test program and move toward certification.”
