Noticed this...

Then took it up again with the same battery...had not charged it again or anything...

I'm giving it another full charge in the drone now and will see what's what.

There's nothing wrong with your battery.
All deviations are in the range 0.07-0.08 volts
That less than 0.1 volt and it's quite normal to have small differences in cell voltages.

Thanks mate. Good to know. Although in the first link there are a few beyond 0.08v upto 0.127 deviation

I've just recharged it and took it out for a night flight. Didn't have any in the red at all.  

Getting more confident with this drone every minute of flight.

Hello there Skynet5. Thank you for reaching out and for the information you have provided. In general, the battery cell deviation should be lower than 0.05V at high power, and less than 0.1V at low power. The third-party software may be inaccurate when calculating the said deviation. Kindly please check the DJI Fly application for compatibility and reliability purposes. Thank you.

Hi Skynet5,

2 examples of my mini2 batterys, as a reference to your question
All normal values.
Btw i have seen so many normal flights, include my MA and MA2 flights, with max cell deviation between 100 and 200 mVolt, never a problem.
Just keep track of the trend.

cheers

Hi,

FRAP software, but the published version works only with the FlyApp version 1.2.1 and lower.

Currently adapting to 1.2.2.
