I'm wondering if there's any correlation between the sub-contractor who made the battery and incidences of swelling or in-flight separation. The battery manufacturer can be found printed at the bottom of the battery label.
My manufacturer was Dongguan Amperex Technology Limited. Go4 says both batteries were made in Nov 2018.
