2 of 4 Antares in USA had notable fires about a decade back (also some
in Europe). These fires were from unspeakably bad electronics design and
nothing to do with the battery system. Fortunately both fires in USA
happened on the ground without too much drama (burned up an electronic
module without spreading).
