BB-TH Thermal Battery Box “E” case
$115.00
Thermal battery box to protect from radiated or convection heat. Fits the “E” case batteries including ETX680/ETX900/ETX900-VNT/ETX1200. 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. The hold-down tab comes with a mounting fixture that can hold a cooling air duct up to 1” in diameter. This battery box was engineered to be strong enough to withstand 30 G of force yet only weighs .49Kg or 1 Lb. 1.2oz.
All batteries have optimal temperature ranges for use in operation. The ETX hundred series is rated for 140°F ( 60ºC) or less for optimal longevity and performance of the battery. Typical lead acid batteries are rated to 113ºF or 45ºC.
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.
