Hi guys,
I have problem with my batteries.
One day, all my batteries started charging for a long time (5 battery packs).
Up to 4 dashes each battery is charged as standard, about 50 minutes but the last line can charge over half an hour.
Anyone had this problem?

I am not 100% sure - but I strongly  suspect that the cell balancing takes place at the end of the charge cycle - which would account for extra time taken at the end of the charge cycle.
It is quite common for Battery Management Systems to behave in this way.
I have asked for confirmation of this but DJI has remained silent on the matter..
Kind regards.
Allan

Lipos are a very funny battery their charging times could be different at times due to balancing each cell.

The only strangest thing is that it happened for all batteries at one time. Maybe it's the charger's fault? or hub?

Hi, Monika. Please provide a screenshot of the aircraft battery and see if the difference between battery cell is over 0.1.
