The FAA's summary their words, unchanged

These special conditions are issued for the Bombardier Model No. DHC-8-100, DHC-8-200, DHC-8-300, and DHC-8-400 series airplanes. These airplanes, as modified by Voyageur Aerotech Inc. (Voyageur), will have novel or unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. This design feature is a rechargeable lithium battery pack inside the Emergency Backup Power Supply. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
