Default A Simple Question About LiFePO4 Batteries

But you can drain a lithium battery "all the way" (to the point

This assumes that all lithium batteries have a full-featured BMS circuit
that protects against battery abuse. That seems to be a bad assumption,
particularly for LiFePO4 batteries. Pfiffner has posted some
interesting failures he's seen there, in the previous incarnation of
this discussion.
