Great job! I do this with most of the batteries the school throws out in the e-waste bin. Two main things, first off that homemade 18650 charger is really nice! great job on it, it looks very professional! Second, great idea using the magnets on the alligator clips for the charging! I have quite a few ver small neo magnets that I could use to hold them to the terminals of my batteries. I used to use rubber bands to do it but they would always come off. Keep up all the great projects and the youtube channel!
