In case you thought cars would become safer as technology developed… rest assured, Tesla is finding newer and ever-dumber ways to make their cars dangerous to occupants (and others).
TL;DR: If you’re in a Tesla and it loses power (like in a fire), the only way to open the doors is often an unlabeled wire behind either two panels or a speaker grill. Tesla owners are DIYing janky rip cords to make that wire easier to pull to escape.
I wouldn’t even feel safe if I had a close electrician friend strip the batteries for use as a house battery.
They have a huge safety-orange pull tab that disconnects the two banks of the battery. But even then you shouldn’t operate on them unless you are trained. 350 VDC is no joke.
I’d mount them outside or in our detached shed.
