Hi, I bought my Latrax Alias in August (5 months ago) and I bought 3 extra batteries. All of a sudden my quadcopter has a flight time of less than 1 minute on all 4 batteries. I was getting about 15 minutes before but now I can only get maybe a minute. Sometimes if I do 100% throttle from a take off the battery voltage warning starts beeping immediately so a flight time of basically zero. The batteries are on the charger until the red light on the charger turns off and then I plug them into the quad copter and have almost no flight time.

Is there anything I'm doing wrong? I don't understand why they would all of a sudden stop holding a charge.

Is it normal for these LiPo batteries to stop working after 5 months of average use?
