the second External Battery.

Charging sequence
1. The internal battery of the Astral device is charged first.
2. Once the internal battery is fully charged, the External Battery
(Battery 1) is charged next.
3. If a second External Battery (Battery 2) is connected, it is
charged after Battery 1 is fully charged.
Note: The batteries are discharged in the reverse order (ie, the
internal battery is discharged last).
Setting up for mobile use
The External Battery is ideal for mobile use (ie, with a
wheelchair) when backup power for the Astral device may be
required. In mobile situations, regularly check the charge on the
External Battery.
Note: The Mobility bag has a compartment capable of holding
only one External Battery. If travelling with more than one
external battery, wait until the first external battery is depleted
(as indicated by the Using internal battery alarm) before
swapping over to the other external battery. The Astral device
will continue to ventilate using the internal battery while the
external batteries are swapped.
