2022 VoltAero announcement reports over 200 Wh/kg at pack level; do not transfer to other configurations or EPiC 2.0.
SkyDrive selected EP Systems for SD-05 battery development in July 2022. This historical selection does not identify an EPiC version or establish the current configuration, production delivery or approval.
EP Systems’ website contains both an active TSO-C179b approval-project description and a 2024 certification timeline. No regulator-issued authorization has been verified here, so neither that timeline nor the SD-05 aircraft program establishes battery approval.
