Aosenma CG035X Owner'S Manual Download Page 38

The voltage on a correctly functioning stock charger (with
no load) is measured as 4.8Volts across each cell. 
Pin 3 is ground (or – terminal, furthest right). Pin 2 is cell 
1, pin 1 is cell 2. So if you put the negative probe of the 
multimeter on the negative pin of the charger and the 
positive probe of the meter on pin 2, you get a reading of 
4.8V. Now move the positive probe to pin 1 and this gives
you a cumulative value of 9.6V, 4.8V per cell, if you move
the negative probe to pin 2 this shows you the value for 
cell 2, which again should be 4.8V. If you do not get quite 
near these values, the charger is probably broken and 
will need to be replaced

If the battery and charger check out as ok then the issue 
is within the drone, look inside the battery bay and if you 
can see a damaged Deans T connector then that is 
probably the issue.  

If looking inside the battery bay you see nothing 
untoward then you may wish to open the chassis of the 
quad for further inspection. 
Another possibility is the red and/or black power wires 
are not soldered correctly onto the main board, or at the 
back of the T plug, check this for faults too. If everything 
is ok it should look as pictured here.
