The common problem for measurement and element ( in this case batteries ) is how to make it. In my specific case, I want to analyze the behavior of the batteries 18650. Commonly these batteries are used for storage, electric vehicles, vaporizer, and others. However in the case when it is building a pack commonly is created by soldering with a point solder and stripes of nickel.
In this project the idea is to create a simple structure to hold the batteries and have fourth points measurement. also will explain the reasons to be selected that type of solution.
This project it is a mix between a diary of the events and (research and test).
Enjoy this project?
