These used/refurbished batteries always have less than 25% of total charge cycle usage  (20 to 49 cycle charges)

Keep an eye on the number of times your battery has been charged in your DJI Go 4 app. Most of the time, around 200 cycles is when the battery may start to be less reliable, but always check the health of the cells in your app and make sure the battery status is normal before flying.
