So, this was a stick pack (shotgun style, shrinked) that went boom. I don't trust these packs at all because there is no way to equalize the cells in the pack prior to charging. There is the chance that one cell had much more of a charge in it than the others and you didn't notice the temperature building in that particular cell.
When cells near the end of their charge, instead of storing electrons, they convert them into heat. A cell is a sealed device, and will build pressure when heated. This pressure vessel usually has vents that are supposed to release the pressure build-up before a detonation can occur. The newer cells have a lot less 'dead space' than the older cells, therefore less compressible gas area. This is one of the reasons the newer cells are more temper mental... I know nothing of the chemical reactions...
Battery matching companies sometimes have really great customer service and may help out in certain situations. I am also sorry to hear about your table.
When I get a new pack, first thing I do is discharge the pack and equalize to .9v. Then I charge at about 7.5 amps with a 3mv/cell delta. No mercy. Charge, run, repeat.
