Overview
|
Note: Not FAA Approved. Intended for use in experimental aircraft only. The ETX400-24-VNT is a deep cycle backup aircraft battery. However, it can also be used as a starter battery in limited applications that require cranking amps equal or less than 290 CCA. Also, this battery is fully protected by an integrated battery management system (BMS). The BMS protects the cell’s from over discharge, over charge, short circuit, temperature, plus cell balancing to ensure charge levels are equal. Additionally, the ETX-Hundred Series aircraft batteries have redundant electronic circuits and battery fault indication. The fault indicator can be connected into your EFIS or wired to a 24volt LED light on your instrument panel. The fault light will alert you to the state of charge and state of health of the battery. (Please see manual for details). In addition to the BMS, this battery has thermal runaway containment and venting designed to meet all the DO-311a and DO-160 requirements for a lithium battery in aircraft. The ETX400-24-VNT is for experimental aircraft, however a TSO approved version is estimated to be available in mid 2025. |
