OP, I know you are running a mech. With that said, one of the many things I like about regulated mods is that a person can often get by with certain bad practices that may otherwise be disastrous on a mech. But, no matter what type of a device a person is using, it is always better to think safety first and to err on the side of caution.
This entire issue of safety that everyone talks about on here is simply due to the type of electronics we are all dealing with. If we were dealing with the electronics of say a small 9v radio receiver then all of this safety talk would be a moot point. But due to the high currents that are involved with these high drain batteries then things radically change. Just like with any small electronic device, you are not going to run the risk of getting electrocuted from it. However, because these vaping devices need powerful batteries that can deliver lots of current flow then you have to deal with possible battery venting, explosions, burns and things of that sort that you don't have to deal with in many electronic devices. In order to prevent these types of events a guy has to be extra cautious.
I hope you do get a better battery (for safety reasons) and that you continue to have a happy and safe vaping journey.
