Dude, why would you want to waste a 20 dollar battery like that? Micro Rcs are just like that, their charge doesn't last long.(One thing you could do is charge it twice to get 6 min. of life). Although it is strange that the battery would fry it like that though, good question.(I think the ZZMTs max voltage is about 5 volts, anything more means the scrap heap for your monster.) That's all I know. Although if I were you, I would clean that monster up and exchange it for another. Then, if the SP battery ain't fryed, try it again.
