This 5400mAh LiPo battery is designed for the Yuneec Q500.
** NOTICE: It has come to our attention that during manufacturing Yuneec mislabeled the flight battery for the Yuneec Q500 Series. All first-run batteries have a label that states 5400mAh when the battery is actually a 6300mAh capacity pack. There is no need to worry as there have been no changes made to the Q500 battery and it has always been 6300mAh. Extra flight time for all.
