Today the test unit stopped again with a LiPo accu voltage of 2.04 V. Recharging was needed.
This test started at May, 2nd and was running 14 days. We had no good weather conditions, but the run time was below expectations. After recharging the LiPo accu the test will be started on another location. The recharging occurs inside therefore you will see room temperature for this period in the graph. Restart at 2016-05-17 9:00.
