Tabitha filled me on the answer:

  test /battery

Alternatively, is there a minimum battery level we can use as a guide
to know if an XO should be plugged in for the nandblasting?

So the steps might be:

  1. boot to ofw
  2. run: test /battery
  3. if the result is above xx, you can blast from battery; if it is
below, plug in the XO before blasting

This is still the goal.

The people executing this aren't technically adept, so I'm trying to
put together simple, low-risk instructions.
