Heli Austria and Heli Werk are offering an EASA-approved upgrade to install a True Blue Power lithium-ion main-ship battery on Airbus EC135 helicopters. Heli Austria developed the supplemental type certificate, and Heli Werk makes the upgrade kit.
Both the True Blue Power TB30 and TB40 lithium-ion batteries are available for the upgrade, which reduces battery weight compared with the existing NiCad battery by up to 19.8 kg (about 44 pounds), depending on the battery configuration. The TB30 has a 30 amp-hour capacity, while the TB40 is a 40 amp-hour battery.
Both are available for all EC135 models, including those with Helionix avionics. The upgrade kit includes the battery, installation kit, and the STC documentation.
“EC135 operators can now choose a complete upgrade solution that combines lower weight, higher capacity, and reduced scheduled battery maintenance,” said Heli Werk managing director Joachim Kies. “Our focus was to turn the approved design into a production-ready kit supplied with the required installation components and documentation.”
“Working with Heli Werk went smoothly from start to finish,” said Roy Knaus, managing director of Heli Austria. “The close coordination between design and production helped us move the project through certification and deliver a solution that is ready for operators.”
