At a glance

Which batteries the Astros use, how many there are, which two have problems, and their firmware.

The Autonomy Park has two sheds with many kinds of batteries in them. The Astro uses the black flight packs with a yellow label on top, shown here, so you can pick them out.

We have 12 Astro batteries. All of them are kept at the Autonomy Park.

Two of the 12 are marked because of problems:

  • One has Cell Imbalance.
  • One has Cell Overvoltage.

It may be possible to ask Freefly how to fix them, but no one has looked into it yet. Do not fly a marked battery.

All Astro batteries have been updated to firmware 2.1.

Two Astro flight packs: black battery packs with a yellow label on top and a connector with a row of indicator segments on the end.
