    Battery charger turns Green, charger settings are:

    LIF
    1A

    Small connector in 3S slot.

    Connect battery to QuadCopter, activate props, it will lift off about 5 feet, drift down to the ground, subsequent launches fail with no liftoff whatsoever, props spin like battery is weak or dying.

    Copter is a month old. Could battery be faulty? Charger settings bad?

    Ideas?

    Should be lipo settings, not life. You may have killed battery. Borrow a balance meter to check? Hobbyking have cheap and good replacements.

    Does the Phantom's back lights flicker red rapidly to show low battery?

    It's in the manual. Charger switch settings; lipo and 2A not 1A.

    hope you didnt toast your battery by not having the charger set to lipo hopefully the charger knew it was not a li-fe and stopped charging it before blowing it.

    ya the red flashing lights means you are out of power and it would auto land if up in the air when you hit the 2nd level on the battery alarm settings in the naza.

    If you dont have a way to check the over all voltage of your battery you can plug in to the naza assistant and under the battery settings tab you can see what the charge voltage is after its charged again using the right settings on the charger.
