I received this battery in June. I balanced charged it with my Tenergy TB6B charger at 1 amp and installed it in my Hubsan transmitter. Seemed to work great. When it got down to about 10Volts I recharged it again. I did not fly for awhile and just got it out last night. Transmitter said it had 11.3 volts so I flew. 2 minutes into the flight the transmitter warned low voltage so I started to bring it back, voltage was at 7 and dropping fast, The transmitter shut off at 5 volts and the drone went into fail safe return mode. This was all in about 3-4 minutes. I took the battery out and it was swollen. I tried to charge it but the charger warned " Low cell volume error" I did get it to balance charge eventually but it only took 300mah. I then tried a lipo discharge cycle at .1 amps and it errors out with the low cell warning showing 2 cells at 4ish volts and the third at 2 volts. I am out of the 30 day return window but thought someone may find this helpful. ScottRead full review

My Sky RC charger indicates that the actual capacity is 1600 mAh not 2200 mAh. I won't be buying these again.
