Today my grandson was driving my CC 6-seater electric golf car and a battery exploding under the back seat. He called me on FaceTime and showed it to me. Everyone was ok and he said it would still run and he drove it home. I maintain the batteries well. Water was proper and all cable connections were clean and tight. Charge was up. The batteries were 5+ years old and they wearing down, but worked. I see that the terminal melted and probably arced and set off hydrogen gas that blew a piece of the top of the battery off. I’ve never seen something like this before. Has anyone had an experience like this before? I’m in the process of building a Lithium battery pack. I guess I need to get back on that now.
