The battery stayed in the seat post. So perhaps I did too good a job padding it and lodging it in there? Also, I was running the seat post at minimum insertion length, so the battery was relatively high up in the seat tube, potentially stretching the wire, but at the very bottom of the post, thus subject to vibration/movement. I doubt this is a very likely occurrence, but an interesting mode of failure nonetheless.
