The beer was mourned. And while lost beer can never be replaced, another was drank in its honor.
I hooked it up to a half dead car battery and let it sit. It actualy took 15 minutes to flame up. That cell had started to puff during charging a while ago. No extra fuel needed, using an iron kettle like that caught all the outgassing and directed it up.
I'd observed in other videos of lipo fires that they vented a lot of gas before they flamed up. My theory was that most of it was lost, blown too far away to burn. I was using the pot to capture it and direct it up into what i hoped would become the flame column. seems to have worked.
