The Quadcopter Battery
Quadcopter and drone batteries are typically Lithium Ion batteries.
Lithium with it’s 3 electrons is naturally a very unhappy metal. It is reactive. It really really wants to get rid of it’s electrons to stabilize it’s outer shell. Lithium is not a naturally occurring element, but is always found as a compound in nature due to it’s reactivity. Science and technology has cracked this energy rich, naturally occurring phenomena. We have finally developed amazing batteries, from pure Lithium, which has to be lab created. We have figured out a way to harness the power of this natural, unstable electrical phenomena and make it so that we can derive the power needed to keep a cellphone charged all day, or to fly multi rotor robots.

Not only is Lithium a very reactive metal, it is also light, allowing us to create batteries that pack a lot of power without a lot of weight.
Our portable energy hungry society has caused battery technology to increase at an exponential rate. Now we have these batteries that can deliver an EXTREME amount of power in a very short time and in a small package. We are getting near the power to weight ratio of gasoline with electricity in batteries such as lithium oxygen batteries, so that might be where the future of lithium technology is heading.
The electrical Power to weight ratio that we are able to achieve with Lithium ion batteries has lead rise to machines like the Telsa, the electric motorcycle and the Quadcopter.
Lithium Ion Batteries are unlocking the power to do things that were only the dreams of our ancestors, and they are making for some amazing technology such as 3d flying, first-person view acrobatic robots. AKA Drones, Quadcopters, QAV250s, ETC.

This machine would not be possible without battery technology. The battery is what makes it work. The exponential development of the battery is why we have seen an explosion of drone technology in the last 5 years. It was simply not possible to harness the power needed to escape gravity in this fashion with prior battery technology. Now, The future is bright.
Especially with batteries such as lithium oxygen approaching the power to weight ratios of gasoline, the future of electric powered flight might look even more promising than it already is.
