So my Quadcopter (apm 2.5) has been getting terrible battery life. It would always exceed 8 minutes, but recently its been getting more like 3-4. I thought something might be wrong with the copter, but I know its not now. I plugged my battery in to my charger for a discharge, but got an error telling me that one of the cells voltage was too low to work, but the others weren't. Now I'm thinking its one of the cells, what do you think? I might call and see if I can get it replaced. Its a flightpower 2200mah 3S. Also, for a new pack should I go with Zippy or Turnigy?
Thanks for your help!
