Ah, yeah, with that many to do I'd want the battery ratchet too I think.

I have an electric impact as well. For around the shop, air is easy (I
close off a valve and the compressor doesn't lose appreciable amounts of
air between garage sessions), so it doesn't get used. At the track, the
battery impact is easier and does most everything I need it to do.
But the electric impact is in the trailer for when something goes wrong
with the battery impact. :-)
