The TB47D is the standard battery for the DJI Matrice 100. The intelligent flight battery has a capacity of 4500 mAh. The higher capacity TB48D can deliver up to 5700mAh. When the Matrice is flying the battery will communicate its remaining power in real time. Sophisticated algorithms will work out how far away your aircraft is and calculate how long it will take to return to its home point. It will also advise you when it is time to bring the aircraft back. The battery is packed with features that will help prolong its life. The intelligent circuitry will automatically give you information about the battery’s overall health and condition as well as the voltage of each of the cells, and the total number of charges and discharges over the lifetime of the battery. An extra battery compartment on the top of the Matrice means that you can double flight time and it will take both sizes of battery.
