When building multiple coils, are they in series, parallel, or both depending on how it is setup?
Series or Parallel

Parallel... always.
Rebuildable atty's that are designed for dual (or triple, quad, etc.) coils generally have 1 positive post and two negative/ground posts/screws (the negatives/grounds are common).
If you are rebuilding dual coils for a clearomizer head, then you simple run both positives together, and both negative together.

Be aware that running dual coils requires matching the resistance of each coil, or one will heat sooner than the other. Electricity is going to follow the path of least resistance.
Also, be aware that the coils must be double the desired resistance, as the parallel coils will share the load and work together. So, if you're after a 1.5ohm result, the coils will be 3ohms each.
It is very important to be safe in building by using a multimeter and not overexerting the batteries safe discharge rating. Dual coils will draw higher amps. Higher amps wear batteries. Batteries can go boom if over-discharged.

Basically, if you put 2 coils end-to-end (series)...that's one coil with a "flat spot" separating them. Like if you put one set of loops on wick A and another set of loops on wick B with one long wire. Or, saying it another way, if you made two coils and welded them together end-to-end.. you made one wire out of it.
So it has to be parallel to be two separate coils.
See cautions in post above.
That's not, exactly, to say you can't do dual coils with one wire
but the positive contact would be between the two coils effectively making two paths as if it wire two wires. So that's parallel paths between + and ground.
