Description

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.

Potential Lithium Ion Battery Testers Options

I will provide a wide range of options from large manufacturer options to commercially available testers to what appears to be step by step instructions for how to build a tester.

Notes

main restricting factors are price, time, and ease of use. If it is too expensive, takes too much time to arrive/setup, or too complicated to implement (or out of scope in general) it is not feasible.

know that the battery pack must be capable measuring

Purpose of measuring the lithium ion batteries will allow us to
