configure cell balancing settings. This includes the ability to change balancing modes, set balancing timers, and
set balancing stop conditions.

4.1 Balancing Timetable
Here, the timers for all of the cells and the module can be set. At the top left, the user can set a timer for All
Cells. In addition, the user can save the current timing profile as a .txt file and can load from it at any time. In
Manual mode, check boxes appear and are used to evaluate whether or not a cell combination is valid.
To manually turn off a cell for balancing, set the timer to 0 seconds and press Run.
4.2 Balancing Sequence
The BQ79616 supports two cell balancing modes: auto and manual. Below are descriptions on how to get
started with either mode.
4.2.1 Auto Balancing
In auto cell balancing, cells are balanced in an odd and even sequence, switching every duty cycle period.
Because the device automatically sets up this balancing sequence, there are no constraints placed on which
cells can be selected for balancing in auto balancing mode.
To configure auto balancing, set cell timers and select a Duty Cycle Time.
