This little fellow came in today - Apparently, in Saudi, dust can be an issue? My read here is, dust piled up, and then they had a slightly humid day, which soaked the dust with dew. I can only imagine what the discharge did to the batteries..

This board might have been saved with an appropriately sized inline fuse.. Circuit protection is a critical function that needs to be addressed.

Requires manual intervention, however. Time to change them in my office...
