Boeing Battery Fire Cause: Bad Wiring?

The Japan Transport Ministry released a report Wednesday saying it found that the battery in question had been improperly wired. The Associated Press citing the Transport Ministry report, said the ANA 787's auxiliary power unit was incorrectly connected to the main battery that overheated. However, the ministry said it still needed further investigation to determine exactly what caused the main battery to overheat.

One claims Boeing had determined that the solution to the overheating problem was to increase the gaps between the battery's individual cells, but the report gave no other details.
