I think he was joking... ...at least I hope he was.

Anyways Finnster, 4s = 18v because you only charge the cells upto 3.6v each, then stop the charge & restart it with the charger set for a 5s pack to achieve the full 4.2v per cell. Its a safety feature in many chargers- you plug in a pack, and if the voltage isnt high enough for the pack vs what you've told the charger it should be, then it will assume you're thick and charge the pack as though it were 1 cell smaller. Kind of annoying, but it does save people from tryign to charge a 2s pack as a 3s etc and burning down their house....
