So what is the critical voltage to be aware of while flying? Gonna be doing some 28-30 degrees stuff tomorrow. Def gonna start with warm batteries and then let it warm up in a hover for a couple min too most likely. So each cell is 3.8v. And the battery voltage indicator gives you a one cell voltage. So wha'ts the danger level of one cell?
 
So it is only showing you one cell voltage up the top right?
That's showing you the voltage of the lowest cell -- which is all that matters. Once the lowest cell reaches 3.0V, the battery will shut off.

Perfect! Had no idea why just one voltage. Thanks for that very good info man!
