H55 delivers first certifiable Adagio battery modules for Smartflyer SFX1 electric aircraft

Bookmark this story

Smartflyer says H55 has delivered the first batch of Adagio battery modules that are “certifiable” for Smartflyer’s SFX1 electric aircraft, marking a key milestone in the powertrain development program. The shipment advances component readiness as Smartflyer moves deeper into aircraft-level integration.

Briefing

What Hype is tracking

  • Battery certification and qualification are gating items for electric aviation; this delivery shows tangible progress from regulator-witnessed battery-module work into an aircraft program’s supply chain timeline, building on H55’s regulator-witnessed propulsion battery module tests and cleared EASA path.
  • For SFX1, getting a “first batch” of certifiable modules out of the component development phase reduces uncertainty on readiness for integration and subsequent compliance steps.
  • The milestone also fits the broader electrification ecosystem sourcing and partnerships around H55’s battery and propulsion system efforts, complementing recent supplier selection activity such as H55’s Safran ENGINeUS power selection for the Bristell B23 Energic.
