I just finished giving the above battery pack a full charge and have it in the airplane. It has a static reading of approximately 5.6 volts. When I apply a 250 ma load with the ESV the voltage drops to 5.4.
I believe when I oringinally checked the battery last night the stactic reading was 5.1 volts and at a 250 ma draw it was about 4.75 volts.
I found the instructions for the Digipace and it discharges at a 300 mah rate.

Does this mean at 5.1 volts I can figure about another hour of flight time, since the complete discharge at 300 ma took 100 minutes?
How does this reasoning sound to you guys?
Thank for the info.
