Exclusive Insights into the eGenius Battery Technology

To compete in the historic 2011 Green Flight Challenge in Santa Rosa, California, the team faced a monumental task: engineering an extremely lightweight, high-capacity, and above all, safe high-voltage battery system.

These 40 detailed photographs document the development, precision assembly, and final installation of the battery pack inside the eGenius. From individual lithium-ion cells and the Battery Management System (BMS) to its custom integration into the fuselage—this gallery reveals the electric heart that powered eGenius to a historic 2nd-place finish in California.

Every single step in this gallery is accompanied by technical descriptions directly from Len Schumann, providing firsthand insights into the engineering decisions, safety protocols, and craftsmanship behind the pack.
