"No if it was in series then it would double the voltage, in parallel the voltage is the same but the capacity doubles."
I know you are a brilliant guy but look at this I believe you are backwards.
http://www.scriptasylum.com/rc_speed/lipo.htmlIn series the voltage stays the same parallel the voltage increases with every cell added.
Then can you explain how a simple flashlight works? You take two 1.5 volt batteries put them in end to end and you get how many volts? How about an auto battery, you have six voltaic chambers of 2 volts each, therefore by your logic it's a 2 volt battery, right? Most people know that it's a 12 volt battery.
