I didnt get any yet but when I do I will get 4 3.7V 5000mAh.

Then you should use a power regulator like an 7805 or 7808 to get to 8V.

Wrong. 78xx regulators are linear, meaning that they can only drop voltage, not boost it. You'd need to feed it at least 10 or so volts for a 7808 to work reliably, feeding it 3.7 doesn't work. Also, a 7805 would give 5 v...

I just assumed he will use his batteries together so that they sum up the voltage.
