One of the batteries i used in a Dell mini latched a warning sign that later after investigating the reason i traced to voltage cell mismatch. An important condition that affects the battery performance. And even safety during the charging. For example: You could be able to limit the charging current when a given cell increases it's internal resistance. With higher current one cell can "suffer". (thus increasing it's voltage and consequently overheating)
This may happened in both incidents. A mere cell mismatch.
The outsourcing of new high tech items (capable to ground an airliner) could be well managed (understood, etc.) by a plane manufacturer. This would require experts not working in this environment. The sophistication of the planes and the amount of innovation creates a very difficult situation.
