We did two things that combined are rather dangerous, though we quickly rectified it

1. We built around the battery (how was this not noticed...)
2. The battery lacked proper electrical taping

So, come time to change the battery, it is in the absolute tighest possible space. Just in the path of the battery is a piece of 80/20. So, when initially removing the battery, the electrodes made contact with the 80/20 and made some rather ominous fireworks. We were, however, able to remove the battery safely, and designed a better removal path.
