Whops I did it again...

[brushlessboy16]

Was out running my matrix today when the truck got really jittery, i would floor it- then it would cutout then the MMM would rearm... so i was fuming thinking that it was the MMM on its way out the door, so I bring it in and check it -mmm is fine- took off the voltage jutoff and checked it with a 9v battery. so then i go and charge the lipo- all is well and charges just fine...so now im confused, I go to unplug the pack from the charger and hear arcing...Uh oh. I immediately grrab the nearest shart object(nail clippers) and tear open my pack. come to find that the copper tab for the + connection on the end cell broke loose from the tab built into the cell...
This is what I found





Im going to attempt to solder it back.. if not its going to the pimp....again...
