Overview

Note: Not FAA Approved. Intended for use in experimental aircraft only.

This battery is fully protected by an integrated battery management system (BMS) that protects the cellís from over discharge, over charge, short circuit, temperature, plus cell balancing to ensure charge levels are equal. Additionally, the ETX-Hundred Series batteries have redundant electronic circuits and battery fault indication. The fault indicator can be connected into your EFIS or wired to a 12volt LED light on your control panel to alert you to the state of charge and state of health of the battery. (Please see manual for details)

If you are looking for a more compact sized battery, the ETX680C has the same specís but in a more compact size. Visit here to see the details of the ETX680C: ETX680C | Lithium Battery for Experimental Aircraft | EarthX (earthxbatteries.com)
