Yea heat is a factor on any lithium battery, the heat it produces and the heat around effec the chemical reaction producing more power. If I remember correctly if a data logger with a voltage sensor on it was to be hooked up to the battery and logg the info you'd actually see, say a 3s 11.1v peek at 12.5 or 12.652v just from the extra chemical reaction from the heat....Sorry for hte partial lecture its a habbit.
