    Just wondering what storage voltage people are using? By my calculations it's around 10volts.
    Phantom battery says go no lower that 2.5 v per cell. 2.5 X 3 = 7.5
    My full voltage = 12.45
    12.45 - 7.5 = 4.95
    I've read storage voltage should be half of capacity so 4.95 divided by 2 = 2.475
    2.475 + 7.5 = 9.975 volts storage charge.

    I have read anything from 3.65 to 3.85 per cell for storage.
    so lets go in the middle:
    3.75 X 3 = 11.25 Volts

    Are we talking about the phantom's 3s lipos here??? Your cells are going to be toast at 2.5v, permanently damaged. The voltage drop at 3.0 is precipitous and you should never go below 3.3 at a minimum. 9.95v unloaded per cell is way, way too low. Do not let your lipos drop that much!

    Ideal storage voltage is anywhere between 3.8-3.85v-cell. In reality, that's kind of a pain if you fly frequently, so I just store at after-flight voltage so long as the recovery voltage reaches at least 11.2v for the pack.
