I plan on leading a workshop on how to create led devices(shoes, clothing, etc), and mostly plan on teaching how to do it with old electronics, like phone batteries. The point is trying to do it as cheap as possible, so getting something like a spot welder is out of the question.
I plan on attaching something like the picture below to the phone battery, and it looks like the only cheap way to do that is by soldering it.
From what I've looked up it looks like the battery can explode
- is this explosion big enough to actually hurt someone?
- How easy is it for the battery to explode for someone with not a whole lot of experience?
- If getting seriously hurt probably won't happen, is ruining the battery a serious concern?
- Is there a better option to connect the battery to a power source?
