NOTICE: It has come to our attention that during manufacturing Blade mislabeled the flight battery (BLH8619) for the Blade Chroma. All first-run batteries have a label that states 5400 mAh when the battery is actually a 6300 mAh capacity pack. Future battery production will have the proper label. There is no need to worry as there have been no changes made to the Chroma battery and it has always been 6300mAh.
