Flight time depends mainly on the drone weight. In order to get flight times above 1 hour on a single charge (as shown here), the weight has to be minimized. Typically the most dominant weight hereby is the battery. To identify the best battery I created a 4S LiPo Battery Value and Capacity Comparison.
- Value can be calculated by Capacity / Price)
- Density can be calculated by Capacity / Weight
The diagram above is sorted left to right by Ranking = Cap /Weight * Cap /Price
