This DJI Intelligent Flight Battery is designed to fuel the DJI Mini 4 Pro for up to 34 minutes on a full charge. To recharge the battery in either the charging hub or inside of the drone, you’ll need the separately available 30W USB-C charger. You’ll gain a full charge in 58 minute with the charging hub, and a full charge in 70 minutes if you charge the battery while it’s still in the drone.
