The four LEDs on a DJI Intelligent Flight Battery show its charge level. Press the power button once to see it: each solid LED is roughly a quarter of the charge, and a blinking LED means that quarter is partly full. During charging, the LEDs blink to show progress. Unusual patterns, like one LED blinking two or three times per second, are protection codes that tell you why charging stopped. All four LEDs blinking together can mean the battery is damaged.

Checking the charge level
- With the battery powered off, press the power button once.
- The LEDs light up for a few seconds to show the level.
- To power the battery on or off, press once, then press again and hold for two seconds.
Read the LEDs from LED1 to LED4. Each lit LED stands for roughly a quarter of the charge, and a blinking LED at the end means that quarter is only partly full. So three steady LEDs with the fourth blinking is somewhere between three quarters and full, and a single blinking LED means the battery is nearly empty and should be charged before flying. DJI's manuals give the exact steps for each model.
The battery LEDs show the level during flight too, but check the exact percentage in DJI Fly. It's more precise.
LEDs while charging
- The LEDs show the current level while the battery charges, so you can watch it fill up.
- Fast blinking means fast charging. DJI's Mini manuals say that if the LEDs blink slowly (about once every two seconds), charging is very slow, and you should try another USB-C cable or charger.
- Charging hubs have their own lights. A two-way charging hub shows status on its own LEDs, which follow the hub's manual rather than the battery's.
Protection codes
DJI batteries stop charging to protect themselves, and an LED tells you why. From DJI's Mini series manuals:
| Pattern | Meaning | What to do |
|---|---|---|
| LED2 blinks twice per second | Overcurrent detected | Unplug, power off, reconnect |
| LED2 blinks three times per second | Short circuit detected | Unplug, check contacts and cable |
| LED3 blinks twice per second | Overcharge detected | Unplug, reconnect |
| LED3 blinks three times per second | Over-voltage charger | Use a DJI or proper PD charger |
| LED4 blinks twice per second | Too cold to charge | Warm to room temperature |
| LED4 blinks three times per second | Too hot to charge | Let it cool after flying |
For temperature codes, just wait. Charging resumes once the battery is back in range. For the others, DJI says to press the button to power off the battery, unplug the charger, then plug it in again. DJI's charging range for the Mini 4 Pro battery is 5° to 40° C (41° to 104° F).
Other patterns to know
- LED3 and LED4 blinking together on Mini series drones means the battery isn't seated properly in the aircraft. Push it in until it clicks.
- All four LEDs blinking together indicates a damaged battery on Mini series models. Stop using it.
- Battery dropping to storage level by itself is normal. DJI batteries self-discharge when idle. On the Air 3, for example, DJI says the battery discharges to 96% after three idle days and to 60% after nine.
Patterns vary between drone families and battery generations, so check your drone's manual for the exact table.
When to stop using a battery
Retire the battery if it's swollen, cracked, leaking, smells odd, or keeps showing a damaged-battery warning in DJI Fly. See swollen drone battery and DJI battery error. If it simply won't charge, try DJI battery not charging first.
