I had this happen a week or so ago. I had a 2yr old Checkpoint 5000mah that broke internally after I nosed on a big double. I have opened them before to repair a connection but this time I punctured a cell and up it went. 30 plus foot smoke cloud for a good ten minutes. If your gonna attempt it definitely do it outdoors.
