6.6 Battery Protection Settings

HIGH, the battery monitor will provide maximum protection for the battery against excessive
discharging. When set to LOW, the battery monitor will allow maximum use of the energy stored
in the battery. The table below shows the voltage cutout levels for the three battery monitor
