I am new to drones and bought a used P3A as my first drone. On my first flight after about 12 minutes the drone went into auto-landing mode after a critical battery warning. It then crashed before completing the auto-landing as the battery apparently gave out. It took a nose dive from about 15 - 20 ft and did a hard face plant hit on the front 2 arms.
Post crash analysis shows that even though the battery reported that at the moment of impact the batteries were supposedly 23% charged, but cells 3 & 4 are bad with voltages of 2.79 and 2.81 while cells 1 & 2 were 3.4 and 3,2 respectively. The visible damage from the crash was one broken propeller, the camera broke free from the drone at the yaw arm and the top shell had damage from a screw being pulled out. I'm waiting for the repair kit for the gimbal and was able make temporary repairs with BJ weld for the screws that were pulled out of the top. A new top is on order.
I had seen videos of P3s flying without the gimbal attached so I tried to see if it would power up and hover. It won't.
Here are the observations when I tried to power on the drone (with a different battery):
Now I am at a loss at what else to look for and any help will be greatly appreciated.
Thanks,
Dave

Here are the observations when I tried to power on the drone (with a different battery):
- Power on - immediatly I can hear a fan running.
- A few seconds later the drone starts beeping loudly and constantly at a rate of two beeps per second.
- The link indicator is green indicating it links to the RC device.
- The led on the gimbal plate is blinking green even though the rest of the gimbal and the camera are not attached.
- The "aircraft status indicator lights" - led lights on the bottom side of the arms never light up at all.
Now I am at a loss at what else to look for and any help will be greatly appreciated.
