6.5.5 Boost (BST) Mode
This feature provides the supervisor with the means to equalize charge the battery at a higher voltage
relative to the connected load. The transition to BST mode occurs when a user-defined condition (custom
alarm) is false.
NOTE: Activation is manual and certain conditions must be met to prevent damage to the load.
A custom alarm must be created to include all the desired factors that must be taken into account before
activating BST mode. This mode is only permitted if the alarm is false.
Once activated, BST mode concludes with a timeout or whenever the status of the custom alarm is true
and reverts to FL mode. BST mode can also be cancelled if the conditions that are required in order to
activate BST mode have changed.

6.5.6 Battery Current Termination (BCT) Equalize
Refer to Section 2.9.3 for an overview of this feature.
Since the BC Threshold is in amps, it has to be set with caution as the battery current input has limited
accuracy. If it is too low, the threshold may never be reached. The threshold should be at least twice as
large as the jitter on the battery current input. If this limitation forces the threshold to be set higher than
desired, the BCT Duration can be increased slightly to compensate.
