My drone was stored for the winter. I put the batteries on the charger, and they appeared to charge up normally. When I put the battery in the drone, all 4 lights come on, then go back off again. The drone will not start up. This is the second year for my drone. Last winter they came out of storage, charged up and flew without issue. Not sure what the problem is with both batteries this spring, but when trying to turn either battery on, all 4 lights come on, then they go back out again.
How are you attempting to turn on the batteries?
What do you see if you press the battery button and release it quickly when it’s not in the drone?
All lights come on for about 20 seconds, then shut off. This happens when the batteries are either in the drone or out of it.
