Why is it so hard to imagine that it works for many / most but there is still a problem? Poor design doesn't mean a design that never works. It can be just "Good enough for many / most" yet problematic.
You assume that only poor design can account for your unusual battery failure. You also speculate that there could be something about "your riding" that caused the failure. Again, what is so special about your riding that you think it may have caused the failure?
The fact is that your battery may have broken due to issues during manufacturing, which is a completely different failure mode than the "bad design"/"my riding broke my battery" that you are speculating about.
