If you are looking to buy a drone or have flown a drone before, then you must have noticed the notorious low battery-life that they have. For smaller toy drones you can expect to get about 4-5 minutes of flight times & for some of the bigger, more expensive drones you can only expect about 20-25 minutes of flight time. And don’t get me wrong, those are respectable flight times but if you compare them to the amount of time it takes to fully charge the drone then you can see that it can be an absolute nuisance.
