Re: How can minibot battery short circuit when it isn't on or being charged?

I am going to go on the assumption that the battery was dropped at some point and damage to the insulation as Mike has pointed out above eventually led to a short between cells. In a dead short, even one cell is capable of full current discharge for several seconds. You can consider that the battery is capable of at least 20 amps sustained since that is the value of the fuse.
