I almost had a similar disaster while charging Lipos on my quad charger. I was charging several Lipos and a Lead Acid battery but had gotten the leads mixed up and found later that I was charging a 3 cell Lipo with the 12V Lead Acid setting. Thinking it was a Lead acid battery, the charger kept pumping in 2 amps even after the Lipo was fully charged and over voltage. Luckily I came back to check and found the voltage was a volt or so over but no puffing or worse. Not sure if the battery is damaged from this and I'm still using it. As said in the previous posts, need to be careful of settings especially if switching between different types of batteries as the Lipo mode will check for cell count and ask for confirmation, but other battery types have different rules.
I also bend the rules while charging - who really has time to sit watching batteries charging for hours? I at least have them charging in the garage just the other side of an open door from my lounge room while I'm watching TV, so I can sort of supervise them and listen out for the finish beeps. I have been meaning to add another smoke detector in there (garage), (already have 4 or 5 in other rooms of the house), and a fire extinguisher - will probably get 2 - the kitchen could use one as well.
