My first time soldering a Lipo I was shaking like I was working with a grenade with the pin pulled. Put it on charge on a metal workbench in the garage, watched it for a bit and went inside.

I came out 20 minutes later to the entire garage full of smoke.

I thought I burned the damn garage down, talk about your heart leaping into your throat.

Turns out the neighbor lit off a pile of wet leaves and filled up my garage with smoke. FD training took over after a short panic and I realized it didnt smell electrical but for a minute I was thinking of how I was going to explain to my finacee at the time why/how I burnt her house down.
