Except I don't hold the lithium batteries for my laptop, my weedeater, or my drill ----- up close to my face.
Silly or not-----There's a part of me that, first time I saw a 26650 battery in a mechanical, it was so heavy and big......I instinctively thought to myself: I do not want to be using this.
Seems like kaboom! with a 10440 battery versus a 26650 would be somewhat different. I can see how the vents would get closed off pretty quickly in a big batt meltdown, a tiny hole in bottom of a tube mod isn't going to give much "protection".
From what I remember reading from the Battery University, the bigger the battery the better. Of course this was 3 years ago so it may be a bit foggy. Do cell phones not contain li ion batteries?
