saftey wiring lipo's in series and parallel
I am making a flashlight for someone and I want to make sure I am
  absolutely being as safe as possible; I don't want the batteries to
  blow up on them or anything like that.


Do you hate this someone or like them?  

You obviously do not have the requite background to make an Li-ion charger.

If you were doing it for yourself, I'd still recommend you not do it.

But making a charger for someone else is a definite no go.

BUY A FLASHLIGHT.  I highly recommend Coast flashlights sold at Home Depot.

If you wanted to to hurt this someone, Coast makes knives too.

If you have a strong desire to make a flashlight use NiMH. What LED driver did you plan to use?
