Hi, I just notice that if I connect my second battery to charger LED1 blinking. Double check in manual, and I'm sure this is LED1

Hi, sorry for the inconvenience. May I confirm that did the battery can be turned on or be charged normally? Thanks!

Interesting! This just started happening to me but it blinks after it has fully charged and when I press the button it shows a full charge and the blinking stops. What's up?

Hi,

OK, small update:

Today I notice the same behavior. So, I set timer to 10 minutes on my phone and start charge battery. After about 5 minutes, second led (led2) start blinking, then after some time led 3 and led4. All looks like normal charging

Finally my battery was charged to 100%.

In the morning i had chat with dji and they suggest me to refresh firmware using Dji Assistant 2. So, I put my failed battery (charged 100%) to mavic, connected usb cable to PC, started drone, and stated DJI Assistant 2.

In Firmware Update - section Assistant show me following message:
"Firmware incompatibility detected between some modules and current device. Update firmaware?" I confirm update

After while, update finish success, and I could power on my drone. Did not have a time to fly, but so far all looks OK now.

I will update this thread after few flights on this battery - if all good I will close thread.
Regards
