So I was looking at my lipo batteries and one of my packs is puffed a bit. I have two identical trakpower packs and one is puffed and the other one is not. Both have been charged on the same charger and I bought them both at the same time. What do I do? Do I continue to use it? (I do not think that is the best idea) Do I charge it? Do I trash it? I want a solution to this before I charge it and my house goes down.
