Hi all...I am new in this - I purchased used Phantom 2 few days ago, my first flying machine, so I`m novice.

I got 3 batteries with it. Two are a bit swollen but working. 3rd one is 96% health, only 10 charges.

I am getting errors when I connect a battery to the P2. Red light blinking constantly, shuts down after 5 seconds, and FPV shows good voltage, high % of battery, but battery indicator is blinking like it is empty.

So i suggest, that 3rd one is not original. Looks the same as others, but serial number of the bottom does not start

I heard it is possible to downgrade firmware, so it does not detect non-OEM batteries?

PS - i cleaned all contacts with dry contact cleaner...
