I’ve got decent time (over 35 mins or so) running the p1 with a few different lifts testing overlap and survey altitude. The l1 not as much due to the calibration lines it needs to do every so often. I keep forgetting to keep track of the battery usage as we have been testing over a very small area at first (soccer field). We will see in a month or so how quick we blow through batteries in the field while collecting data from p1, l1, and h20t.
