| 50 | Date: Januari 2021 |
| 51 | KernelVersion: 5.11 |
| 52 | Description: |
| 53 | To save battery current, the measurement system is disabled if |
| 54 | the battery is the only source of power. This affects all |
| 55 | voltage, current and temperature measurements. |
| 56 | Write a "1" to this to keep performing telemetry once every few |
| 57 | seconds, even when running on battery (as reported by the online |
| 58 | property, which is "1" when external power is available and "0" |
| 59 | when the system runs on battery). |

| 61 | Access: Read, Write |

| 65 | What: /sys/class/power_supply/ltc4162-l/arm_ship_mode |
| 66 | Date: Januari 2021 |
| 67 | KernelVersion: 5.11 |
| 68 | Description: |
| 69 | The charger will normally drain the battery while inactive, |
| 70 | typically drawing about 54 microamps. Write a "1" to this |
| 71 | property to arm a special "ship" mode that extends shelf life |
| 72 | by reducing the leakage to about 2.8 microamps. The chip will |
| 73 | remain in this mode (and no longer respond to I2C commands) |
| 74 | until some external power-supply is attached raising the input |
| 75 | voltage above 1V. It will then automatically revert to "0". |
| 76 | Writing a "0" to the property cancels the "ship" mode request. |
| 77 | The ship mode, when armed, activates once the input voltage |
| 78 | drops below 1V. |
