Hi folks,

one TB 50 of a pair with about 65 cycles is not transmitting it's discharge level, it's stays by 100%. The app shows battery error, on the other hand the battery is discharging normally.
Information sourced by Details of Battery in app shows that the single cell among eachothers and also in relation to the other battery are working normally. Flight time is the same like normal, charging time for both batteries is equal.
The LED indicater on the battery itself is providing the same falsh information, even when the battery is empty 4 lights are on.

Maybe somebody has an idea how to fix this.

Thanks and Best Regards
Ralph

I saw something similar to this with a battery with 91 charge cycles. I discharged the battery all the way down to about 5% and recharged it. this reset the DJI intelligent circuit and it is working correctly  again

Hi Rich,

i have followed your procedure, charged the battery in full, put it to the drone and discharged it 7%. at first the situation improved but still a difference in percentage about 20 remained.(battery details all cellls good) Afterwards the procedure had been repeated the problem disappeared.
Thanks for your advises and best Regards

Hi Ralph

Great news and I am happy your problem has been corrected. Make sure you keep track of this battery and as a good practice, discharge below 10% every 20 cycles.  

Regarding the new FW update,  I have heard that some of the cell errors (out of balance) issues were corrected after 2 - 3 charge cycles following the update.

All the best
Rich
