What kind of charge control does it use? How does it detect when the battery pack is fully charged?

The best and most reliable method handles each cell individually. Charging two cells in series might be okay as long as the charger can safely detect the point where the pack has reached 100% charge. On the other hand this method also requires a way to connect the charger with the battery pack. That's why I prefer charging the two cells individually.
