Re: How can minibot battery short circuit when it isn't on or being charged?
We had this problem, due to how our battery was installed on our minibot. The battery fit inside a piece of the Tetrix C-Channel which was a little too small for the battery. We had put some electrical tape on the battery and the C-Channel to remove the sharp edges but it wore away. We were prototyping with the minibot one day and I noticed the battery started smoking with nothing plugged in. The C-Channel had cut into the battery and was shorting the batteries together. The battery got quite hot and took about 20 minutes to cool down to safe levels, but after wrapping it in electrical tape the battery has been fine in operation. Since this event we spread the C-Channel wider and use zip-ties to hold the battery in place instead.
