Ussualy on 3s it gets at 3.6v each cell and goes to 30% speed but it cuts out instead now mhm maybe it was just aMine just shuts off suddenly also. Then the battery is to low to charge so I have to charge in nihm mode for 30 seconds to gain enough charge to charge in Lipo mode. I figured it’s something I have to set up to give a warning when the battery gets low. I’ve been meaning to learn more about it.
