Burned my MMM!!!

[Urgeoner]

Ok, I used my e revo for the first time since I built it, and it was going pretty good! I used the Castle Link to set the cutoff voltage for 19.2V I am running a 6s battery(2 3s connected in series). Then I saw smoke coming from under the body, and I though "Oh $#it this is bad"...and then the flames just shot out from under the body as well...the one battery just blew up! I though that mostly happened when charging not running them... The other battery seems ok because I used it to test the esc and motor after I got the burnt one off the car. Here are some pics of it, I know they're crappy:




Since it still works, I would like to still use it. Anyone know if Castle would send another case to me?
