It has a beeper that will beep and let me know once it has reached that level. When it beeps and I bring it in and land it and check the voltage it's always higher (like 7.6-7.8). So I believe the current draw is causing the lower number even though once settled the lipo is reading out higher.
Well, obviously the voltage under load is going to be lower than the resting voltage. A old pack could well read 3.85 at rest but sag down below LVC under load.
