Most of the electronic nanny features on regulated mods are there to protect the electronics, not the user, with the exception of the short protection, which is covered by a fuse or hot spring on a mech. Because they drive the batteries so hard at so low of a charge voltage, regulated mods also need undercharge protection, which is the point the electronics say to each other, "Hey we better quit brutalizing the battery before we kill it." That's a situation a mech user is unlikely to even get near.
Are you speaking of a low-voltage cut-off? I would hope my regulated mod has one. Over discharge can kill an IMR battery. I don't see your point.. I put a battery in, vape at a regulated voltage, and enjoy the same consistent vape for hours until the battery drains. Not much to worry about at all... With my mechs, every hit drains the battery more and more.. The hits get weaker, and weaker. I still use them, but I'm aware of their limitations too...
