LiS is only 10x below gasoline. When you account for the difference in efficiency, and the the difference in weight for the motors, and then reliability and redundancy, it is roughly a factor of 2 away. That is fine for shorter routes. Recharging time isn't an issue, just have the batteries swappable.
