. One of the main attractions of the DJI Matrice 100 is its adaptability & flexibility. Although it can fly for up to 20 minutes with a standard battery underneath adding a second one in this extra compartment on top of the quadcopter can give it a theoretical maximum flight time of 40 minutes. The compartment can take either the 4500 m Ah TB47D or the 5700 m Ah TB48D. Thanks to adjustable mounting holes on the module the battery compartment can be moved around to adjust the multi-rotors centre of gravity which will be affected by the payload that its carrying. Thats vitally important for a platform which will be used for research & development work. With two intelligent batteries on board you will still receive important information about overall battery life health & status & how much time you need to allow to get your Matrice back to its take-off point..
