This 26V battery pack will provide superior starts on all aircraft, including voltage sensitive, electrically-started turbine engines that cannot accept a true 28V battery pack, such as the Eclipse 500, Phenom 100, Phenom 300, Agusta AW 139, Agusta AW109 and the Sikorsky S-76. It will also provide 50A or 105A continuous power for powering up aircraft systems.
