Currently, unmanned aerial vehicles (UAVs) are not only used for the military but have also been applied to agriculture, energy, and transportation. One example of its application is by conducting environmental monitoring, agriculture, and survey applications. This UAV has very specific constraints on the driving force of the drone starting from the power needed, the costs incurred, its weight, and the durability of the flight. The main reason is the fact that UAVs are unmanned, so the weight is relatively less and does not require a life support system for the crew and passengers, making it ideal for this new technology. Also, fuel cells are still too heavy to push large aircraft; they have a lower power density when compared to conventional turbines. In this study, we want to see the development of the technical feasibility of lithium battery packs for drones / UAVs. Because in business developing this lithium battery pack can increase 20% value-added products. The method used is a qualitative method by looking at and comparing similar companies. The purpose of this study is to see the technical feasibility of lithium batteries for drones with a technical review from the literature review and previous research.
