FAA Grants EarthX AML-STC for 12v Lithium Batteries
EarthX has earned FAA Approved Model List (AML) Supplemental Type Certification (STC) authorizing the installation of its FAA TSO’d 12-volt LiFePO4 battery on a comprehensive array of single-engine Cessna, Piper, and Mooney aircraft, as well as the Aviat A-1.
An AML-STC is a multi-model approval method allowing a set of compliance data—e.g. type design data and substantiating data—to be designated as baseline data applicable to various aircraft models.
EarthX sales director Kathy Nicoson stated: “At EarthX, innovation is the core of our mission. We exemplify this commitment in the aviation industry by being the first company in the world to offer an FAA TSO-approved 12-volt lithium battery. We are extremely proud of this accomplishment and are excited for a growing number of owners to benefit from all of the advanced features and capabilities the EarthX LiFePO4 replacement battery will bring to their aircraft.”
EarthX’s new-generation LiFePO4 lithium batteries facilitate:
- Weight Savings of over 23 pounds compared to equivalent lead acid batteries.
- Increased cranking power.
- Battery life-spans of over six-years.
- Full recharging in minutes rather than hours.
- Ease of Installation by dint of an included (with STC and installation kit) battery-management system that alerts operators of abnormal battery conditions.
The FAA TSO’d 12-volt LiFePO4 12V battery and STC retail for $699.00. The cost of the installation kit varies by aircraft model.
Single-engine (Textron) Cessna models included on the initial AML STC include:
- 120/140

The AMS STC applies, also, to Aviat’s A-1 model.
Ms. Nicoson added: “EarthX, Inc. is passionate about battery improvement in the aviation market and has invested many years in an extensive R&D program followed by the in-depth FAA approval process. The end result is this AML STC, which will allow our lithium-iron-phosphate batteries to challenge the status quo and bring undeniable benefits to aircraft owners.”
