Hi everybody,
I have a DJI Mavic Pro battery that otherwise checks OK but when I try to fly it gives me the message "Battery Authentication Failed" and I am unable to take off.
Any advice or help with this matter would be greatly appreciated.
Thank you in advance for your help!
Paste NLBA1 BatInfo picture.
Hi,
I will do that but I have a question, is there a way to connect to the battery to get the information requested without opening the case again?
Also I do not have an NLBA1 I am reading the battery via EV2300.
Thank you!
Do you have DJI License ?..
Yes I do.
Did you copied the very first initial eeprom ?..
No.
Read the battery and paste BatInfo page picture.
Hi,
Did you see my question above?
Is there a way to read the battery without opening the case of the battery? If not just let me know and I will open the battery again and give you the requested info.
Thank you!
Smbus interface located on the Pcb. On the battery connector UART interface is located. These are different ports. Yes, you need to access the pcb to connect NLBA1 device.
OK
Thank you!
I will open the battery and post the requested screen shot.
Make sure battery is switched Off by push button and LEDs not lit.
Then go to Smbus tab and send these commands with 5s interval
Register 0x23 ReadBlock
Register 0x23 ReadBlock
Register 0x23 ReadBlock
Register 0x00 WriteWord 0x0054
Register 0x23 ReadBlock
Then paste snapshot of the log
Register 0x00 WriteWord 0x0054
This command was sent not correctly.
WriteBlock was pressed instead of WriteWord button.
