Please educate me as I always thought capacitors were potentially dangerous things...... If safe enough then I am onto building a set up for my Lupo 3L

These capacitors are safe, but not all capacitors are safe.
These are safe because they can only be charged to 2.7v each, and strung together in series could only be charged to 16v. This isn't enough voltage to electrocute.
That said, you wouldn't want to touch the positive and negative leads together without a load in between because it will discharge so quickly that it could weld the object touching the leads.
If you are handy with a soldering iron, I would suggest
this kit on Ebay. You would spend that much on the capacitors alone if you purchased from Digikey, and it comes with balance components and a PCB.
