Battery Issues

[aerialimagery]

I have P4P+.

Today I tried using what appeared to be a fully charged battery, but when I attempted to use it, I got the "cannot take off" warning as well as another pop-up warning about the battery needing to be changed because it is low. However, the battery itself was lit up with all four bars and my controller said it was at 94%. I tried using two other batteries and everything worked ok. I tried several more times with the first battery and continued to have the same problem of not being able to take off and the pop-up of the low battery.

Any ideas of what's going on or what I can do? Thanks.

What aircraft are you flying that is giving you this problem?

It's possible the battery is out of balance (cell wise). If it's Dji what are the battery specs in the DJI Go App?

He has a P4P
If it was a fully charged battery and you are only showing 94% I would guess you have a weak cell and once a load it placed on it the voltage probably drops.
Check all the pin connections on the battery and make sure they are clean and secure.

As BigA said, do a cell check
