Yep and fire hot enought to melt metal.Ive never seen a cell "explode" with force though, only venting gases....
however the explosion is unually in a mech mod where the mech cannot vent the gasses fast enough and the 510 or top of the mod pops shooting into the person holding it near their face.
Bottom venting in mechs kinda sucks unless the cell is positive towards switch.
the cell expands when it heats up when venting happens and will not let the gasses get down to the switch end, and they WILL go somewhere.
Many/most non vaping literate refer to mods as the battery. And that is it's main purpose...
Bathubs...
Man I gotta go take a shower....
Wish me luck.
