The conversation between human and AI assistant.
Why are drone and quadcopter flight times so short? Is the technology for lightweight, high-capacity batteries not here yet or is it a cost issue?
Is the technology for lightweight, high-capacity batteries not here yet?
Actually, there has been a lot of progress in battery technology, and we now have some very lightweight and high-capacity batteries available. However, these batteries are still relatively expensive, which makes them less practical for mass-market drones and quadcopters.
