What guarantee do you have that the seller will be in business next
year, let alone 15 years from now?

And the sun could snuff out tomorrow, life is chancy. With your
viewpoint we'd all still be huddled around the fire afraid of
the dark. There are no 100% guarantees about anything but your own
mortality.

Yawn. I built a 48 VDC powered KU band communications system for the
International Space Station while working at Microdyne. Lockheed-Martin
packaged it into one of the custom rack modules and supplied the
modified remote control software to NASA. It was a modifed Microdyne
'700 Series' design.
Cheap and long life just don't go together on batteries. If someone
actually did discover how to do it, they would own the market in a very
short time.
Huddle all you want, around your jury-rigged toys. As far as the
fire, you might get that from you overloaded and under designed 12 volt
wiring.
