Hope you'll keep us posted on specifics. From your mention that he was using Lifepo4s, it seems likely that he was stacking them. Unequal charge between stacked batteries has been known to cause battery failure though "word on the street" has been that the Lifepos wouldn't violently out-gas.
The flashlight and airplane hobbyist forums have had occasional stacked battery tragedy stories for years.
Same Here ... Kona, from what I've seen ... If a Lifepo4 has an uneven charge (as compared to the 2nd battery being used) -- The battery itself almost "shuts off" and has to be charged just to "Reset" the battery. I've had this happen on a couple less than stellar batteries I've used over the past several years.
The worst I have seen Lifepo4's fail in my 3 years of selling Lifepo4's is a repair I just got back a couple days ago.
The spring was completely warped, and the batteries shrink wrap shrunk (as most do as the batteries get hott) and that was the worst I saw. (The user had pounded the adapter -- hammer marks on the stainless steel -- thus causing the unit to short atomizers.
I tried googling other Lifepo4 failure's, and haven't seen or heard of a single one. Tenergy even tested trying to explode their large Lifepo version battery:
Tenergy LiFePO4 Battery Safety Test - YouTube
I also contacted Tenergy and they have never heard of one of their Lifepo4's failing like what was described.
What I also don't understand about this story is how the "user" was using it and mid hit, the batteries exploded. If the batteries were shorted (and over discharged to cause a failure of this nature) -- it wouldn't activate the atomizer. The atomizer would be stone cold & not producing vapor. It would take a good 30-60 seconds to heat up to the point where you couldn't hold the tube (I've tested this myself).
So, there are a couple questions I have about the story.
1) Were they indeed Lifepo4's that failed? I could see Li-Ion batteries (Perhaps even the AW17670 - if the protection circuit failed)
2) In a post of yours, you state the user had this happen "mid hit" -- To go from working 1 second, to exploding the 2nd, doesn't seem to make sense to me.
3) Assuming a short caused this to happen -- The user wouldn't even be able to handle the V3 since it would be so hot, just to the touch. Were there any
4) Did the user drop his V3 or do anything prior to this even happening?
Keep us posted!
