Clemens Aviation has become the launch customer for the True Blue Power TB40 lithium-ion battery STC kit, upgrading its fleet of Hawker/Beechjet 400s from lead acid to lithium-ion main ship batteries. Clemens is a full-service FBO, maintenance facility and private aircraft management company based in Wichita, Kansas.

True Blue Power's Gen5 TB40 (40 amp-hour) advanced lithium-ion main ship battery has been STC approved on Hawker/Beechjet 400 series aircraft. The ultra-lightweight TB40 reduces Hawker/Beechjet aircraft battery weight by up to 60 pounds, increases useful load, generates faster turbine starts and improves performance.

“The TB40 lithium battery is a game changer for our fleet of 24 Beechjets,” says Alex Clemens. “Between the cooler starts, weight savings and increased dispatch reliability, we were sold on the TB40 immediately.”

The STC kit, developed with certification resource Peregrine, includes: one TSO-certified Gen5 TB40 advanced lithium-ion battery, one Mid-Continent Instruments and Avionics Flex digital battery annunciation control unit (ACU), installation hardware and manuals.

“The certification of the True Blue Power lithium-ion batteries on the Hawker/Beechjet 400 has taken the collaboration between our companies to new heights,” adds Peregrine VP of business development and administration TJ Spitzmiller. “This STC demonstrates how True Blue Power's lithium batteries continue to meet and exceed new FAA safety standards.”
