When load testing a NiMh, or NiCad, when you are using the digital servos 4@9252, and 1@9256 what is the minimum voltage you should see when in the .5, 1.0, or 1.5 range for a safe 10 minute 3D flight. Saying you are using a 2400Mah, and 3300Mah Battery.
I've tested by discharging after flying, then calc the approx MAH per flight. Then discharge a fully charged battery and plot the discharge curve (voltage vs. MAH) under two or three test amperage loads. With a discharge curve and the approximate MAH/flight you can estimate minimum voltage under a test load.
Results will vary quite a bit depending on battery selection, temperature, resistance in switch/connecters, etc. See www.voltmagic.com/faqs.htm near the bottom. MAH capacity is only half the story, voltage drop under load is the other half.
