  • Battery guard thresholds: below the low threshold the modem stays off (Iridium held off); below the critical threshold both radios stay off. Starting values are offered for 1-cell and 4-cell LiFePO4 packs; check them against the battery datasheet. A banner warns when battery protection is disabled.
  • Status LEDs: Normal (default, about 0.25 mAh per day), Minimal (faults and battery warnings only) or Off (power-on self-test only). See Status LEDs.

The battery voltage shown by the app is uncalibrated (a few percent of error). A LiFePO4 cell rests at about 3.2–3.3 V for most of its capacity and is nearly empty below 3.0 V.
