title_body: Can I use LiHV batteries as normal batteries? I have a small drone and the only batteries I can find that fit it are LiHV batteries. Can I use LiHV batteries like normal LiPo batteries? Can I just simply charge a LiHV battery to 4.2v and fly with it?
upvoted_answer: Yes, you can. The primary difference between LiHV and LiPo batteries is the ability to change them to ~4.35 V/cell instead of 4.20 V/cell with a nominal cell voltage of 3.8 V instead of 3.7 V.
  
  Just like how there's nothing stopping you from only charging your LiPos to 4.1 V/cell instead of their rated full charge @ 4.20 V/cell, there's nothing wrong with charging LiHVs to a "full" charge below their rating.
