Great point! Adding more tabs could theoretically reduce internal resistance, but it likely comes down to cost, manufacturing complexity, and existing design optimizations. The 4680 design is interesting, but widespread adoption would take time due to patents and the challenge of scaling. It’s a bit like solving a puzzle — sometimes the simplest solution isn’t always the easiest to implement. If you enjoy these kinds of brain teasers, Riddles for Kids has some fun ones to try as well!
