OK...obvious question, Why did it burst? It appears you have 2012 unit, so I assume the batteries are 1 year old. What happened and why?
He may just never know why.
Without a truly knowledgeable person to inspect the now open battery, there is no way to know.
Odds on are that a cell in that battery shorted, then was overheated with the power for the other batteries and the gas in the cell ignited. This is not uncommon in situations with LA batteries in parallel. The real snare is that the short heavy load on the other batteries in the common bank may also have been damaged. This is difficult to detect.
Just one of the reasons I don't like to build systems with LA batteries in parallel.
