I feel your pain. I too had become very "layed back" when caring for lipo's. So much so that I had been charging in my trucks. This was a Maxamps 6500 pack that had been in a hard head on crash with my 1.1 van tire. I had been having an mgm esc braking issue. After the crash, the truck sat on my bench for about 4 hours and no I didn't even check anything , I got ambitious after the 4 hour break, charged up the one pack (all seemed ok, I did balance charge with a 606i ) It took about 50 minutes and put 5000 mah into the pack.( I came back 90 minutes later , charger said complete and all seemed ok). So I put my charger on the other side, went upstairs and about 15 minutes later......BaBoom, Not just fire, a big bang . By the time I realized what had happened (and got back downstairs) all the big flames were done and I was left with a smoke filled basement, a bench on fire as well as a whole buch of other things. I too was very thankful Kiddie was there to "put out the basement". I know better but had just got to use to not having problems........Never again !!!!!
