I went for a ride with a buddy in his Jeep, been out about an hour and back about 20 min when we heard this loud "BANG"! It was like a shotgun going off! We went and looked at the Jeep, the 12v battery had blown up! Put another battery in it, everything was fine!
I don't care what you do, how you do it, how safe you think you are, there is NO SAFE battery! They are a storage
device holding a lot of energy and must be respected!
