Airwolf Aerospace has received FAA supplemental type certificate (STC) approvals to install True Blue Power TB17 main-ship lithium-ion batteries in 10 helicopter models. The STCs cover the Airbus AS350/H125, AS355, EC120, and EC130/H130; Bell 206A/B and L through L4; Enstrom 480B; Hiller UH-12E; and MD Helicopters MD369/500. Other STCs are in the works.

The battery kit includes the True Blue Power TB17, annunciator, wiring harness, and mounting hardware. According to Airwolf, “This is everything required except weight that may need to be added in some installations depending on the weight and balance of the helicopter.”
