Fun!!
The Exide that blew probably already had a weak cell. The cell reversed polarity when its voltage was drawn down low enough, with the result that current passing through the battery began charging that cell.
That explains why it was bubbling furiously - you were probably stuffing a lot of current through it. Maybe 75 amps? 100?
It makes sense that removing that battery from the string made things go faster, because you effectively took a big battery charger/resistor out of the loop!
