Overview

FAA REQUIRED STATEMENT:
“The conditions and test required for TSO approval of this article are minimum performance standards. Those installing this article either on or within a specific type or class of aircraft must determine that the article installation conditions are within the TSO standards. The article may be installed only according to 14 CFR part 43 or the applicable airworthiness requirements.”


EarthX is excited to update and upgrade one of the oldest technologies still used in general aviation with the FAA TSO approved ETX900-TSO model lithium battery! This lithium iron phosphate battery will provide you a massive weight savings, increased life span, and more cranking power.
The FAA approved 12V ETX900-TSO designed for certified aircraft. An STC or DER assisted Part 337 (field approval) is required for installation.

This aircraft battery has electronic protections (BMS) and built in thermal runaway containment and venting ability built in. The ETX900-TSO meets all of the DO-311a and DO-160 requirements for a lithium battery in aircraft.

ETX battery series is fully protected by an integrated battery management system (BMS) that protects the cell’s from over discharge, over charge, short circuit, temperature, plus cell balancing to ensure charge levels are equal. Additionally, our ETX Hundred series aircraft batteries have redundant electronic circuits and battery fault indication. This battery also has fault indication that 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. (Please see manual for details)

Reviews

So, be prepared to be surprised at the footprint of this battery. Going from a Concord to the EarthX is night and day. Cranking amps are way up, charging system runs strong, I have every confidence this battery could keep the electronics running for a good amount of time in the event of a charging field failure. Be warned, it’s footprint is MUCH smaller than what you’re used to. You will need to secure this in your battery box (we used high density foam to isolate it in the center). Overall, can’t recommend upgrading to this enough.

Battery is not suitable for a firewall install. The manufacturer does not list this information in their STC as they should but hide it in their website FAQ.

Q: Is this EarthX ETX-900 TSO battery a replacement battery for Cessna U206B?

It has the correct power specs for the aircraft but it would need a 337 for install.

Q: So, who provides the STC with the EarthX ETX-900 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.

Q: Is this EarthX ETX-900 TSO 14V Aircraft Lithium Battery a legal, direct replacement for a Baron 95BE55?

No, a 337 would be required for this application.
