In fact the battery pack itself is labelled 238.5WH:

Actually I think the "2" is "-2" on the end of a product number: PB10KPC04-2

Capacity is then 38.5WH, at about 4V that gives about 10,000mAh. Probably not coincidentally if you google that product number you get various chinese pages advertising similar things at 10,000mAh.

Thanks; that makes much more sense.

Conception tragedy - 34 dead

Not an airplane, and the NTSB isn't finished, but Lithium batteries are under suspicion.

Looking at the FAA video I was curious why a CO2 extinguisher was not tested. CO2 changing state from a liquid, which it is in the extinguisher, to a gas gets very cold (I'm a wine maker and use CO2 as a cover gas all the time) generating solid CO2 (dry ice) which is pretty damn cold. As cooling the battery is the critical step...... I use siphon CO2 tanks where the liquid is expelled through the valve vs the gas from the top of the liquid as in a regular tank. Regular tank gets pretty cold also.
