We use similar batteries where I work. They go on charging runaway about once a week. First the smell begins. Then the heavy sulphur smell feels heavy in your lungs. Then the smoke begins. At that point I throw the disconnect from about a hundred yards away and wait until the stink clears. Then I call the battery company who comes out and replaces the unit for about $23,000 dollars. It’s a good business to be in. That is until someone decided to get them approved for an airworthiness application / use! Vehicles on the ground have a use profile of maybe two hours a day. Aircraft run 24/7 until a maintenance cycle.

Not sure if the design of the batteries is Boeing's or that of the battery's Japanese maunfacturer, GS Yuasa. Japan's equivalent of the NTSB says there are no problems in the manufacture of the batteries:

Attention is now being focused on the circuitry controlling battery current flow. Don't know who designed those components.

Over 20 years ago we used lithium batteries in offshore submersible seismic equipment. They blew up all the time. Luckily it was usually at night sitting on the rack instead of while someone was handling the equipment.

Well, DUH!

Even my R/C Helo instruction manual has a 2 page warning about the lithium batteries must be watched at all times during charging because they are prone to fires.

The FAA really doesn’t do much in thir certifications. They read practically no documents, test nothing, and take the word of whomever provides the docs that the docs accurately reflect the actual system.

Shocking images which were released yesterday of the charred remains of the battery which spontaneously combusted in Japan. Pictures released by the Japanese Transportation Safety Board showed the blackened lithium device with frayed and broken earth wire.

Charred to a crisp: The burnt out remains of the lithium battery from a Boeing 787 which investigators are examining in Japan.

Grounded: The fire on board an All Nippon Airways flight forced the plane to make an emergency landing last month.

Damage: A ground wire which was attached to the burnt battery is showed charred, frayed and broken.
