Sometime in 2011 (we can’t be sure when), an airport worker hooked up an energized ground-power unit to a Cessna Citation CJ4 (525C), according to the FAA. The CJ4 was the first business jet certified with a lithium-ion main-ship battery.
Mid-Continent Instrument and A123 Systems signed an agreement for Mid-Continent to distribute and supply A123 lithium-ion battery technology for the aviation market. “Mid-Continent’s True Blue Power division will work with customers to develop custom power solutions using A123’s innovative lithium-ion chemistry for a wide range of aviation-related applications,” said True Blue Power division director John Gallman. This includes A123 lithium-ion cells, modules and custom power solutions.
True Blue Power (Booth No. N1911) announced that it is providing its MD835 nanophosphate lithium-ion emergency power supply on the Nextant 400XT, replacing the lead-acid emergency power supplies on the Beechjet 400A.
Under a contract signed by Eurocopter Deutschland and Mid-Continent, Eurocopter EC135 and EC145T2 models will be equipped with Mid-Continent Instruments True Blue Power MD835 emergency power supply systems.
Mid-Continent Instruments has received an approved model list (AML) supplemental type certificate (STC) from the FAA for its MD835 lithium emergency power supply. The award is the first FAA Part 23 approval for a lithium nanophosphate battery through the AML STC process. Thirty aircraft are included in the STC, including the King Air 90, 200 and 300 series, Beech 1900, Beech Premier and Cessna Citation 501, 525A/B.
Mid-Continent Instruments' cutting-edge lithium battery, the MD835 emergency power supply, has received TSO certification from the FAA. Lithium nanophosphate is an aviation-friendly type of lithium chemistry that does not have the characteristics of thermal runaway that legacy lithium-ion batteries have, Tom Genovese, director of sales, told AIN.
