Everyone is suffering (or will suffer) from Air 1 battery problems.

Here in Brazil there is one guy refurbishing Air1 batteries with Ai2s cells.

I Bought one - it gives me 25 (really) minutes of flight time :-D

Until now, 10 flights, not a single problem.

That is great to hear that you can get such good flight time of refurbished batteries. Congratulations, but what about warranty of your drone if any problems?

My Air has 3+ years of service. No warranty anymore.

Hello there Adriano Araujo. Good day and thank you for sharing this interesting information with us. Have a safe and a happy flying always.
