The DJI Intelligent Flight Battery is a 4480mAh, 15.2V Li-Po 4s battery that is specifically designed for the Phantom 3 series so that you can get the best possible performance from your aircraft. The battery will give you up to 23 minutes of flight time. It also also has built-in sensors and bright LEDs that let you know the status and remaining power of your battery in real time. The slot-in design means that there are no cables to get tangled and no need for a separate balancing lead because of the built-in intelligent charging system. It always pays to have spares with you. Don’t forget that batteries must be charged using a DJI approved adaptor.
