I sometimes charge to 4.3v a cell... NO issues...


I know what I'm doing, IDK if the person next to me does though...


'overcharging' your batt is not dangerous if you know what your doing and have 'good' batteries(new, not puffed, low IR, etc). Its not until you get joe schmo that wants to get every last race out of his $150 battery that is 4 years old, puffed, and about to blow on its own, that you start to have issues...


Pay attention to your batts and you won't have any issues...
