With the concern of lipo batteries catching fire I did a little experiment with one of my brand new dji batteries. After getting it in the mail I made the mistake of clipping off the XT60 connector with a pair of wire cutters. Did both leads at once not thinking about the positive and negative grounding out. Ruined the battery in a few milliseconds. Anyways in my frustration I went out to the back of my house and smashed it into the concrete as hard as I could many times over until it was so deformed, smashed and ripped open. Then let it sit in the sun for the next day and then tried to light it on fire the next night. No such luck getting it to catch fire. About the only way to get one to explode is to charge it with incorrect charger not approved for lipo charging or I guess overcharge it for a prolonged period which with most of the current charges would be very hard to do unless you really tried to bypass the chargers safety features. I've been using lipo batteries for close to 4 years and I have pretty much no fear of them catching fire or exploding. I guess the danger hype isn't a bad thing since there are some real moronic people out there but the fire risk is way over rated.
