To be able to participate in the open class we must design and manufacture a new battery. The battery will consist out of multiple cells. We will use the battery cells from Molicell, we have chosen the INR21700-P45B 4500mAh cells for the design. These cells are commonly used in a wide range of applications, including electric vehicles and portable electronics. In order to design and manufacture a battery using these cells, we will need to consider several factors, including the desired capacity and power output of the battery, the required form factor and dimensions, and any safety and regulatory requirements that apply. Once these factors have been determined, we can begin the design and manufacturing process, which may involve sourcing the necessary materials, designing and prototyping the battery, and testing and refining the design to ensure that it meets your specifications and requirements.
