Syseng68K: I'm sure they will make it work with LI batteries, as it is proven technology in other
areas...
Adding ~100 lbs* of 1/2"-thick stainless steel fireproof case (as reported by sources not permitted to report such things) plus miscellaneous paraphenalia to permit the occasional battery to "safely" self-destruct sounds more like saving face and short-term shareholder value than good engineering. *[per battery, guestimating 12"x12"x12" case, stainless steel nominally 4.7 oz/cu-in]
