Hi i need to reduce voltage of a 4.2v protected battery which is in a circuit. I need the output to be 4.1 or below it .. Also it's not important to do it by not fully charging battery. Any simple solution?
Yes exactly, idk why , maybe protection circuit is broken but that battery exxceds 4.2 easily . I need a solution to prevent that from happening.(by not letting it to charge to 4.2 for example )4.2v is maximum charging voltage for LiPo battery and should not be held at that voltage.
Normal battery range is 3.7v to 3.9v so if you truely need 4.1v you will require a buck-boost DC-DC converter.
