EVO II center battery lights flashing

  1. One of my Evo 2 batteries two center lights started alternatively flashing today and will not shutdown. When in my Evo 2 the console states "unknown battery". Unit will not fly but does power up. The two flashing lights continue to flash when on charger. Consequently this began when I was doing the latest firmware update earlier today. I plan to let battery drain until lights quit flashing and then try charging it.
  2. Apparently the last firmware update did not complete because I was prompted again today. I wondered if this had anything to do with my battery issue so I used the battery in question for this update. Sure enough, once the update was complete the two center lights quit flashing and only the far left light remained on. Battery is now recognized by the controller and taking a charge. Interesting.
