DJI Phantom P3A battery only has 4 cycles and it continues to have cell #1 showing subpar values. Build date is 6-18-15  I got it in late July as part of the 2nd battery deal for new P3A
Cell #1 voltage is lower in voltage after full charge by .3 volts than other cells and after only a few minutes of flight goes to yellow scale in battery page of App. I have cycled batt to 50% each time as per recommended LiPO care and feeding. Cell 4 has .2 volt higher volage than cell 2 and 3 after charge. reading about Lipo batts this is also awarning sign that all is not well. using Healtydrones diagnostic on this batt show cell one has many deviations during usage. How do i go about getting this issue resolved? Also when new it only showed 4120 Mah capacity and is getting worse    only had 4130 Mah cap when new
