The lipos are a tricky thing. A ton of the videos that you see of them exploding and or catching fire due to damage and they always seem to need to sit for an hour or two (I'm assuming to become wildly unbalanced) before they go up. I get kinda irritated when people ask if a lipo bag i needed, is your house needed? lol it's just not worth the risk for a $20 lipo bag or a surplus ammo can, to me anyway. These things need respect but if you give it some then you will have a pleasant day. My $.02
