Hi , I am using DJI550 , and the battery parameters saved in are as follows.

The plots of the flight can be seen here

The problem, is that I connect two charged batteries, LiPo with 4 cells, and the FCU gives battery drainage warning too soon, sometimes, after a minute , sometimes, couple of seconds. When I connect this battery to other drone, the other drone considers it fully charged. Is there anything I can do to fix this situation?

Just in case someone else encounters such problem.
If battery calibration does not solve the problem, try changing the power module.
