Default Voltage Drop @8.4V - how much? (7025LMT)

Hi Folks,

I installed this nice 7025LMT in my new 800 Suzi Laos.
Setup is 12s ->BEC ->8.4V, RJX HV Servos (0.05ms, 21kg) - known as moderate amp drawing.
I played a little bit on the work bench and noticed voltages from 8.5V to 7.4V in my V-Bar.
There was no Stress on the Servos or bent Rods!

Is the Voltage drop in a normal Range?
Is it better to switch to the 7.4V Setting?

Thanks for your advises

I would set to 7.4v, i do this with kosmik and hv servo. Those servos are high amp draw setting to 8.4v makes it worse! Set to 7.4

Are you guys running 12s right into the Gryphon or just wiring it to one 6s pack?

Wow! Do you guys know if the advertised constant and peak amps are applicable at all voltage input ranges? I ask this because many BECs quote available amps based on input voltage, with the best performance being on lower input voltages.
