After the flight, wait until the drone battery has cooled down before connecting it to the corresponding DJI Power SDC fast charging cable; otherwise, charging speed may be affected. Since the final 5% of charging a drone battery (from 95% to 100%) is completed via trickle charging, the charging speed is relatively slower. You can consider using the battery after it is charged to 95%, as the operating time will not be significantly less than it is when fully charged.
