Managing a hot molten salt pool is not as difficult as trying to deal with many lithium cells.  You mention dropping cargo containers on site, but that is not the whole problem; you need to manufacture these containers and have a way of continuously monitoring the cells, either finding and isolating the &#x27;bad&#x27; ones, or replacing whole containers.  In addition, the molten salt will last far more cycles than the batteries, while costing less to replace and being simpler to service.
