All you need to do to confirm voltage at startup is look at the screen. If you do not see 41.7 volts or more, don't fly that pack.

Yes, but what happen if I forget to look at the acreen?

Is it possible to make a alarm for that?

Look at this video (38 second) there are 3 voltage readings.
http://www.dailymotion.com/video/xph...dio_shortfilms

1. Receiver – 5.2V (after the regulator)

2. External – 6.7V (that can be the battery motor)(up to 70V, see 18MZ manual page 25)

3. 2.voltege – 6.6V (that can be the receiver battery)

I assume that the 2.voltage is connecting to the S.BUS2 port.

If that is truth, maybe it is possible to connect another one to the S.BUS2 port and to read the motor battery voltage and define an alarm to be activated if the battery is not full (41.5V for example)?
