Yoobao EN200W Battery Repair

Let's repair the battery of this Yoobao EN200W Power station. This took a long time to record because I had to show every step and possible issues that you can encounter with the battery. If we are not recording, a quick capacity test on the cells as our 1st step would be faster and we could replace the cells in just one day.
