I got the issue and fixed the problem.
On the battery door there is like a sliding mechanism to open and keep it closed. If you take the door apart there is a thin piece of insulating plastic type tape that got worn through and there are contacts underneath it that got shorted.
I Broaght a Paranormal 250C a few months back secondhand. It was working fine for about 2 and a half months.
One day I was driving and took a drag and it was fine when I took a second drag it started getting hot. So hot on fact that I got scared it will catch fire and I could barely hold it...
