overcharger lipo battery grrrrr

IMO the dangers of lipos are greatly over stated I have been using lipos for about 4 yrs now and the only time I have had an issue with a lipo was due to an error on my part,I kept it connected while in storage for about a month, it puffed and I disposed of it. I have charged lipos using Hyperion 0610i using only the output leads and balanced afterwards and had no problems so I would say it was voltage setup...The Hyperions are about fool proof as a charger can get...I have my diffent lipo packs already programmed into the chargers memory and I will always double check the parameters before charging
