Cordless drill battery packs.? Answered

I have a ridgid impact. It cuts off when im assuming the curuit board inside the battery senses to much load. ide like to fix this problem with an override on the circuit board or just bypass the board itself but i need to know, does the battery charger know when the battery is charged or does it need feedback from this curcuit board in the battery? thanks

Which drill is it? You said Impact(r), so I am guessing it is this one: http://www.ridgid.com/Tools/R82320-Impact-Driver/EN/index.htm

I think I have taken apart similar drills and battery packs, but I do not recall seeing any sort of circuit board inside the battery pack.  That is for the old style NiCd and Ni-MH batteries.  BTW the number 14.4 in the advertising copy kind of implies this kind of battery, since 14.4 is a integer multiple of 1.2.

I think I've seen circuit boards inside Li-ion battery packs, and the rumor for those was that this was a circuit to prevent the batteries from being overcharged;i.e it would open a switch upon sensing the batteries were completely charged. I don't remember what exactly was being sensed to indicate the fully-charged condition.  Probably voltage or temperature?

I dunno.  If you want to rewire you batteries (whatever kind they are), or bypass some circuit-thingy,  I say do it!  Sounds to me like you're just trying to find the courage.   I mean if the darned thing isn't working anyway,  how much more damage could you do?

*I stand corrected, answer, singular. I was thinking of another similar question recently.
