title_body: LiPo 4S battery's output voltage higher than 14.8v I have a LiPo 4S battery which the output should be 14.8v but it outputs, fully charged, 15.6v. The issue is that I have a voltage limit of 15v on a non-drone device that gathers data from sensors. So, my first thought would be to discharge it a bit until it drops below 15v. Does that make sense?
  Also, I would like to know if that &quot;over voltage&quot; can be avoided?
upvoted_answer: As others pointed out, 16.8 volt is what that battery should be reading (unless there is a specific chemical composition that makes that different).
  Discharging a battery to use with your application is an anti-pattern, please avoid.  Put a voltage regulator in there with the correct amp rating (draw) and you will be all set.
  Pololu has some 1-2a 12v step-downs that cost $3-10. You can also go adjustable, here is a 9-30v 1 amp step up/down.
  I know a few good ones on Amazon. Bottom line, this is a common part, easy to use, and I have had high reliability for nearly identical situations.
