Discharge rating: 1C continuous in the launch announcement. Pack integration, format, cycle life and temperature-specific performance are separate.

Source conflicts / limitations: No claim that this cell is installed in a named piloted aircraft. Q4 2026 is an availability target, not a completed delivery milestone.

Aircraft applications

Manufacturer targets HAPS, fixed-wing drones and other long-endurance applications. Its historical AALTO relationship does not establish installation of this exact new cell.
