Li-Ion Battery Chemistries - What are the differences in their safety? | E-Cigarette Forum
I just don't trust mechanical mods at all really. I mean if you drop your device, or are simply carrying it around during travel and a short occurs, how in the world can you tell? Or you get a hotspot somewhere and your resistance suddenly changes, there are zero warning signs with these things, even if you're not intending to go full sub-ohm.
With regulated devices being so cheap these days, I really don't understand the allure of mechanicals.
(Just my 2 cents - plz don't hate!)

Simplicity. Reliability. Durability. Knowing it will work or that you can fix it with the simplest of tools if it doesn't.
If we didn't have the sword of the FDA hanging over us, I might feel these attributes were less important, but we do...
the link you posted does not support your claim. many early chargers use temperature rise to determine when a battery was fully charge. that link shows temperatures that you could not hold in your hand.anything over 60C would be painful. some mods may insulate users from the heat for a short time.hobbies have been flying electric powered airplanes and helicopters using Li-PO batteries (the most dangerous on your list) for a lot longer than sub ohmers have been around and operating them at discharge rate as high as 40 amps.but you don't see a lot of stories about these aircraft exploding.most of these hobbyist know their batteries better than most vapors.I have seen them vent and even catch fire in competition where they are pushed well beyond their rated limits.these batteries are sent with a warning and safe use instructions but they are intended for sale to consumers.

Well, when you are the safety mechanism, you get into certain habits. Like inspecting batteries when you insert and remove them. If you drop your mod you check it out, look at the contact points, open your atomizer to make sure the coil and screws are still good, etc.I just don't trust mechanical mods at all really.

Are you sure about that? Got a reference or cite or something?
I could see a charger using using temperature as an indication that the charge rate (current) is too high, but not that they are full.
electric power tools use Li-ion batteries and there is a reason some of them have 3 connectors on the battery pack.the 3rd lead connects to the temperature sensor inside the pack.I flew my first electric powered airplane in 1979 using Ni-cads and a 20C discharge rate so I have a little experience with batteries.
they should be charged with a constant current/constant voltage charger that cuts off at a certain current level but some of the products coming out of china do not do this.this is an unregulated industry and their are some companies that show little regard for the safety of their customers.I use the same charger on my vaping batteries that I use on my model airplanes that allows me to monitor the condition of my batteries as they age so I know that its safe.my mechanical mod has a locking ring on the bottom switch that keeps it from firing in my pocket and I never vape at over 20 watts (5 amps). these accident in vaping are very rare and always caused by the user acting in a reckless manner.
I am wondering what happened to the protection circuit on the18650 batteries that everyone used to talk about and why would it not safeguard against mods

ICRs are the types that generally use these protection circuits you speak of.
Nowadays, it comes down to them being retired for the purposes of vaping...well, for various reasons. I do remember a time when people used protected and unprotected ICR cells in various devices, though.
IMRs rely on the battery's chemical composition itself (instead of a protection circuit) to provide a layer of safety. ICR cells are at a higher risk of exploding due to their composition, and if the circuit in an ICR (a protected ICR - not all ICR batteries have this protection circuit) fails, it's much more violent than when an IMR cell undergoes a catastrophic failure.
Interestingly enough, many fixed-battery devices that do not rely on single internal 18650s utilize Lithium-polymer batteries... or at least, they did. I am unsure if this is still the case.
As far as Hybrid/IMRs with protection circuits? I don't even know if they exist, honestly... would there even be an added layer of safety if the device itself compromised the battery?
EDIT: Here's link to a relevant blog post by Baditude on batteries

Aside from the less safe chemistry of ICR batteries, I think much like the fuses that are available, the pcb's that are on those protected batteries don't allow enough amps through before shutting down for many vapers.
