re: WHY2025 badge batteries | goof lyrics @kitten from what I read (and made assumptions based on it) assuming it has a metal casing below the plastic coating is that either battery terminal really shouldn't get into contact with the metal shell because otherwise it might cause a short circuit, causing overheating and a thermal runaway which results in a fire or even explosion.

re: WHY2025 badge batteries | goof lyrics @kitten idk! It's a lot of assuming and a lot of figuring it's astonishingly hard to find concrete and easily understandable information why the plastic tingy is important.

Please do your own research and don't take my word on that since I have no clue and the effects of being wrong on that can be extremely dangerous. It could also be there for different reasons.

re: WHY2025 badge batteries @kitten imo I'd snip or sand off a bit of the battery holder so it doesn't touch it in that part and maybe add some electrical tape or something to that part :o

WHY2025 badge batteries @kitten TL;DR: It doesn't increase the risks.

Long: 18650 cells are more or less a minus pole all around except for the little tap at the end. That's +. Puncturing the outer plastic does nothing to the stability of the cell itself. The plastic is just a protective heat shrink. I have replaced it on a lot of cells that had signs of wear (a friend uses those for her vape). Big holes however expose more of the negative pole shell and with that increases the risk of shorts.

WHY2025 badge batteries @kitten I didn't get the whole story around the badge but as the battery holder is exposed I would recommend getting some protected cells. They have a little PCB with protective circuit hidden under the heat shrink that shuts of in the case of over (dis-)charge or shorts. The little dent at the end in the pic looks like those might even be protected cells? Hard to tell. If they are they should be 2-3mm longer then the nominal 65mm.

WHY2025 badge batteries @kitten however with protective cells puncturing the plastic is a bit more of an increase in risk (up to the same as a unprotected cell) as that opens up a new connection point that would bypass the protective circuit. So yeah. If it's a normal cell and you are fine with the general risk of a bare 18650 a bit of tape (or a new heat shrink) should be just as safe as a new cell. But I would recommend putting in some protected cells.
Hope this helps :)

WHY2025 badge batteries @dressed_in_rope from the specs I found online they are unprotected. I considered getting protected ones, but I didn't know if it could interfere with anything that might be in the board designed to operate with unprotected ones

WHY2025 badge batteries @kitten Does the badge include a spot welder function? That's about the only (very sketchy XD) thing I could imagine having a problem with that.
Jokes aside: The only difference is minuscule higher standby drain (as the protective circuit burns a tiiiiiiiny bit of power) and a few Milliohms higher ESR. For the circuit it just looks like someone put a closed switch between the cell and the battery holder that only opens in an emergency.

re: WHY2025 badge batteries @kitten this is just plastic touching the metal shell inside the shrinkwrap, youre fine from this in particular - feels a bit scary to have a battery inside it anyway, at least without a case

re: WHY2025 badge batteries @tudbut I am planning to print a case for it. in any case right now it's resting without much handling or moving so it should be safe

thanks!
