    Discharging Hydrimax 4.8v NiMh receiver pack

    Still learning about the battery's used in my plane. I have a 4.8 volt hydrimax ultra 2000 nimh pack and I'd like to know how many amps to discharge and what to set the cut-off voltage at. Anyone have any idea's on this?

    A receiver pack should tolerate a 1C discharge rate - 2A, in this case. I'd stop it at about 0.9V per cell, or 3.6V total; look at charted discharge curves, and make your own judgement: https://www.google.com/search?q=nimh...w=1729&bih=930
