title_body: Alternatives to LiPo batteries
upvoted_answer: Many people choose to use Lithium Ion batteries on long range builds.
  
  They have a very large capacity and I have seen them give in excess of 20 minutes of flight on a quadcopter.
  
  The reason that they aren’t often used for other purposes is that their current output is less than LiPo batteries.
  
  This means that whilst they are good for long range flight, they lack the power for aerobatics and racing.
