Our 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. The fault indicator can be connected into your EFIS or wired to a 24volt LED light on your control panel (SOLD SEPARATELY) to alert you to the state of charge and state of health of the battery. (Please see manual for details)
EarthX is proud to be the most trusted brands in the experimental aircraft market.

BB-TH-U Thermal Battery Box “U” case
$125.00Add to cartFREE SHIPPING IN THE USA!
Thermal battery box to protect from radiated or convection heat!
The EarthX thermal battery box is designed to protect the battery in engine compartment installations from periods of high temperature (up to 1 hour), such as after shutdown, and from radiant heat from hot surfaces like exhaust systems during and after flight. This stainless-steel box has a mirror finish to minimize the effect of radiant heat, and it has a high-performance insulating foam layer between the box and battery to reduce effect of convection heat. Weight is .68Kg or 1 Lb. 8oz.
All batteries have optimal temperature ranges for use in operation. The ETX hundred series is rated for 140 deg F ( 60 deg C) or less for optimal longevity and performance of the battery. Typical lead acid batteries are rated to 113 deg F or 45 deg C.
This battery box is designed to be compatible with our existing “U” case battery models; ETX1600, ETX900-24, ETX680-24-VNT.
Model BB-TH-U
The “Convection” graph shows the battery (not cell) temperature rise with a test environment of 185 Deg F (85 deg C). In this case there was a 5.3X improvement in the time to heat up the battery.
