Description

A detailed description of the scope and motivation for this project, as well as any relevant resources

For the actual satellite, the Electrical and Mechanical teams are building a custom battery pack to house our 4 Lithium Ion batteries. This won’t be ready for a while, which is inconvenient because we want to be able to plug our batteries in and test them ASAP. Is there something we can buy (i.e. something like the photo below) or make (i.e. a PCB) to achieve this goal? That’s your job to figure out. This datasheet includes the dimensions of the batteries: https://batteryservice.bg/wp-content/uploads/2018/12/INR21700-50E.pdf. If you realize that you need other information during your investigations, feel free to ask.
