Inspire 1 v2.0, critically low battery warning and motor overload simultaneously

[BradM05]

Multiple times while I was flying my DJI Inspire 1 v2.0 it simultaneously gave a critically low battery warning and a motor overload warning even though the battery was at 40%. I don’t think it was the battery as I flew it several times and it flew fine half of the times and the cells were giving an even output. Its temperatures also seemed fine. Any ideas why this happened?

...half of the times and the cells were giving an even output.

How do you know this? Were you monitoring all the cells in the DJI Go app as you were flying?

I guess I don't know what output it had right when it happened but shortly afterwards they were giving even output.

You have to watch the output while on a hard ascent. If any cell goes in the red - and I'd bet dollars to doughnuts you have one or two that will - that red cell will trigger a warning.

I will try that

Check what parameters are reported in the logs before and at the time of the notification.

I did check the flight log but could not find anything out of order.

I flew my Inspire 1 v2.0 with all my 3 batteries and watched cell outputs. I found my one battery was giving weak cell voltages, down at around 3.3-3.4 Does this mean the battery is shot?
The other two ran good voltages but had variations of up to 0.2V I ran them to 0% and recharged them to even the cell voltages and they seem to work great now.

Is my battery junk if it produces cell voltages of around 3.4V?
