<p>Yeah, I watched this video a few months back when I was replacing
the timing chain and phasers on my 2012 F150. Saw this thing
hanging off the battery and wondered what it was. Apparently
they're really concerned that you have adequate battery juice to
power things like electrically assisted power steering, auto
stop/start, etc. And will start turning off accessories if
necessary.</p>
<p>I can't imagine that they would prevent the vehicle from
restarting just because the computer thinks the battery is dead,
but who knows.</p>

<div>An interesting topic! I didn't realize how sophisticated
these BMSes are. I found a video that explains the Ford
version very well: <a href="https://youtu.be/I_KmO-KaR4A"

<p>The BMS was my first thought. In connecting to the
battery posts to start the car, you would be bypassing
the BMS, so it wouldn't "know" about the charge and
would think the battery was still dead. But this would
have affected the Lexus (which had the dead battery),
not the F150.</p>
<p>Other than that, I agree. I can't think of any reason
it would cause damage. Just don't put the two batteries
in series.</p>
