> I'm pretty sure your frame wasn't designed to carry this 22 pound battery or anything like it Presumably bike frames are designed to carry larger riders? 22

  Bicycle frames are highly optimized to have the loads concentrated at specific points, namely the seat, bottom bracket, and wheels. The lugs are heavy, and the tubes are very thin almost everywhere else. This appears to be putting load at focal points along the thin wall regions. Every time you hit a bump, the battery hits the frame, like hitting the thin wall of a soda can with a hammer.
