 ## Battery profiles
-Up to 3 battery profiles are supported. You can select the battery profile from the GUI, OSD menu, [stick commands](Controls.md) and CLI command `battery_profile n`. Battery profiles store the following settings (see above for an explanation of each setting): `bat_cells`, `vbat_cell_detect_voltage`, `vbat_max_cell_voltage`, `vbat_warning_cell_voltage`, `vbat_min_cell_voltage`, `battery_capacity_unit`, `battery_capacity`, `battery_capacity_warning`, `battery_capacity_critical`

 To enable the automatic battery profile switching based on battery voltage enable the `BAT_PROF_AUTOSWITCH` feature. For a profile to be automatically selected the number of cells of the battery needs to be specified (>0).
