The ETX900-TSO Certified Aircraft battery is only 5.4 pounds and can be used in an aircraft that has an alternator/generator with 80 amps output or less. This battery has electronic protections (BMS) and built in thermal runaway containment and venting with 2 venting tubes that are 3 feet in length each. The ETX900-TSO meets all of the DO-311a and DO-160 requirements for a lithium battery in aircraft.
The battery also has an LED battery fault light indicator on the battery itself plus it can be programed into your EFIS or wired to an LED on your panel. The fault indicator alerts you to the state of charge and state of health of the battery.

As the first company to achieve the goal of receiving approval on a lithium battery, EarthX has what is called a FAA TSOa certification. We hold the design approval and manufacturing approval to produce this battery. At release, we will not have any Supplemental Type Certificate (STC)s yet. For you to install this in your aircraft, you will need to get a field approval with FAA Form 337 for your aircraft or wait for the STCs to follow.
