Description: As you may know I have a few hundred 18650 cells. In order to use them I need to know the capacity to determine which cells are good/bad. So I decided to build this automated robot to discharge a stack of batteries at a constant current, timing it and performing calculations on Arduino to store data in an array. This is the first part of this build, where I salvage through 20 year old computer DVD drives for stepper motors to use as linear actuators. The next part will involve me connecting two of these motors together and creating the structure (out of cardboard) to hold the batteries. As well as programming the Arduino further to calculate the capacity. Hopefully the "robot" will be fully functional in the next video to this project. I know this content isn't my usual, but in my spare time I work on many projects like this, I just don't usually film it. Let me know if you're interested in this type of content.
