I haven't used my Phantom 3 standard for a long time. The battery seemed like it charged up but when I put it into the Phantom 3 and push the power button, the four green bars light up and then it goes blank. The Phantom doesn't start up. When I hold the button for five seconds, one light flashes and the others are solid and then goes blank again. Is it the battery? If you think it's the battery, any suggestions on where to get a new one?
Thanks
