We disassembled the primary failed pack. It had zero volts on it and showed a short from the leads to the aluminum case. We unfortunately do not have enough experience in the field to discern any knowledge from the results. It obviously got hot, vented, smells (lithium), burnt through its case into the module below it. The module below also shows a short from one terminal to the case, it still has 4 volts on each series of cells therefore 8V across the module. The module above the failed module shows no damage externally, but is at zero volts. We are open to suggestions on how we are supposed to dispose of the modules.
