Mother nature "fuse" protected POB on ANA 787 when descending to TAK

Hi,

Bear,

Didn't ANA report a drop to zero voltage concurrent with the smoke event?

Yes, battery voltage went to ZERO because mother nature opened the circuit of the BAD DESIGNED BATTERY as i showed in the equivalent circuit of the probable sequence in an earlier post.
