While taking breaks from less entertaining
tasks, I've massaged the original AEC9005
LV warn circuit into a more modern equivalent.
Like the original 9005, it features a robust
pull-down transistor . . . with a little
shuffling of parts, the module can be converted
to a battery low voltage disconnect for
preventing fatal over-discharge of a LiFePO4
battery with no BMS.
Drawing attached.
This is an architectural cartoon, parts call
outs are non-sensical. Next step is to select
appropriate values.
This board will probably assemble on less than
1 square inch of real estate and mount
directly to the solder cups of a d-sub
connector. i.e. very low packaging labor
and expense. Total bill of materials on
the order of $5. ECB's should be really
cheap too.

Un impeachable logic: George Carlin asked, "If black boxes
survive crashes, why don't they make the whole airplane
out of that stuff?"
