i just took mine off the charger, its at 4.23v 99%, which is good, but when i looked at the voltage graph it hit 4.34 while charging which is pretty high. i never noticed my evo go above 4.2. all lithium batters are charged by a method called cc/cv, or constant current until the pack hits the cut off voltage which is normally 4.2 then it drops the charge rate to maintain 4.2v until the charge rate drops to a set point. some lithium battery's have better cut of tolerances but 4.4 is about the top of the safe zone, some battery's will start to get very hot above 4.3v.
