Why does the drone need to change batteries after every 1min flight?

Dear @sibujacob
thank you very much ^^

Currently, the most challenging problem for me is the Jetson TX1 sometimes disconnect with Pixhawk.
The issue is described like this:

Why does drone suddenly switch AUTO.LAND mode from offboard mode when descending? (Failsafe enabled: no offboard)

Thank you very much for your help. Is there any min height setting in QGroundControl, which will trigger the AUTO.LAND mode? During my offboard control descending, the drone suddenly switch to AUTO.LAND mode from offboard mode. I am confused about that and the unexpected switch mode makes the programmed descending drone has a unexpected spike, like the video at 1:47 There is the Pixhawk log and the screenshot of the distance sensor. [image] At the time stamp: from 1686240419 to 1686240…

I will add one more 5V battery to lidar and separately use another 14.8v battery to Jetson TX1.
My current Jetson TX1 and lidar-lite-v3 consume about 1A ( tested them with power supply, there is the video)
Really appreciate your comments again ^^

According to lidar lite v3 document, it consumes 135 mA
19V Jetson TX1 requires 6.5W~15W and can consume 5.5-19.6VDC but do not over 21V
