This paper deals with development and application of Battery Pack for an Electric Kart. A Battery Pack is an integral part of an Electric Kart. This paper highlights the challenges in the development of a battery pack and its application. Since there is a gradual shift towards the electric vehicle from the traditional combustion engine vehicles, there is a requirement of research and improvement in the field of batteries used in an Electric Kart. This paper purely focuses on the development of a battery pack with nominal range and power output with phenomenal charging rate; keeping in mind the economic perspective of the power pack.
