The DJI Mavic 4 has quickly become one of the most popular consumer drones on the market thanks to its impressive camera system, extended flight time, and obstacle-avoidance sensors. Like every piece of technology that spends its life in the sky, however, the Mavic 4 will eventually need replacement parts. Whether you have had a rough landing, experienced wear and tear over hundreds of flight hours, or simply want to keep spare components on hand, this guide covers every essential spare part for the DJI Mavic 4.
Propellers
Propellers are the single most frequently replaced part on any drone. On the Mavic 4, DJI uses a quick-release propeller system that makes swaps effortless. You should inspect your propellers before every flight, looking for nicks, cracks, or warping along the blade edges. Even minor surface damage can reduce thrust efficiency and introduce vibrations that affect gimbal stability and image quality.
DJI offers both standard and low-noise propellers for the Mavic 4. The low-noise variant features redesigned blade tips that reduce aerodynamic noise by up to 4 dB, which is particularly valuable for pilots flying in noise-sensitive areas or recording audio during video shoots. We recommend keeping at least two full sets (eight propellers) in your kit bag at all times.
Motors
Brushless motors on the Mavic 4 are rated for thousands of hours, but they are not invincible. Overloading the drone, flying in dusty or sandy environments, and hard landings can all shorten motor life. Warning signs include unusual vibrations, grinding sounds, or one arm running noticeably hotter than the others. DJI uses 2008-series brushless motors that deliver excellent thrust-to-weight efficiency. Replacing a motor involves removing four screws on the arm, disconnecting the three-phase wires from the ESC, and reversing the process with the new unit. Always recalibrate the IMU and compass after a motor swap.
Gimbal Assembly and Ribbon Cables
The three-axis gimbal is what separates DJI drones from toy-grade quadcopters. On the Mavic 4, the gimbal assembly includes three brushless motors, a camera module, and a set of delicate flat-flex ribbon cables. Ribbon cables are particularly vulnerable during crashes — even a minor impact can kink or tear them, resulting in gimbal errors or a black camera feed. A replacement ribbon cable kit typically includes the main signal cable, the yaw motor cable, and the roll motor cable. If you plan to do the repair yourself, use a plastic spudger rather than metal tools to avoid shorting components.
Battery
DJI Intelligent Flight Batteries use lithium-polymer (LiPo) cells with integrated battery management systems. Over time — typically after 200 to 300 charge cycles — you will notice a decline in total capacity. The Mavic 4 battery provides approximately 46 minutes of hover time when new. When that number drops below 35 minutes under the same conditions, it is time to consider a replacement. Always store LiPo batteries at a storage charge level (roughly 50-60 %) and avoid exposing them to temperatures above 60 degrees Celsius or below -10 degrees Celsius.
Landing Gear and Body Shell
The Mavic 4 features integrated landing gear on the bottom of the airframe. While DJI has improved impact resistance with reinforced polymers, hard landings on concrete or gravel can crack the landing skids or the ventral shell. Replacement landing gear snaps into place with two retaining clips per side. If the top shell is cracked, replacement requires removing the battery, propellers, and a series of Phillips-head screws along the arm joints.
Sensors and Vision Systems
The Mavic 4 is equipped with an omnidirectional obstacle sensing system comprised of multiple stereo vision sensors and infrared time-of-flight modules. Sensor glass can crack from impacts or accumulate scratches that degrade sensing accuracy. Replacement sensor modules are available individually — you do not need to replace the entire set. After replacing a vision sensor, run the sensor calibration wizard through DJI Assistant 2 to ensure accurate depth mapping.
Remote Controller Components
The DJI RC 3 controller that ships with the Mavic 4 has its own set of consumable parts: joystick covers wear down over time, the built-in screen can crack if dropped, and the antenna assembly can be damaged in transit. Replacement joystick modules, screen assemblies, and antenna covers are all available. We recommend a hard-shell controller case to prevent transport damage.
Conclusion
Maintaining a healthy stock of spare parts is one of the smartest things any drone pilot can do. It transforms a potential multi-week grounding into a 30-minute repair session.
