The intelligent battery circuit is responsible for keeping your batteries heathy. Some manufactures call this the BMS or ""LiPo Battery Management System"" When everything is working, ...all is well. But DJI has a sealed system which prevents the owner from correcting minor problems. When a battery cells become severely out of balance (for whatever reason) the DJI BMS cannot recover the cell(s). In my case the battery was new (only 1 charge cycle) and it would not charge up the # 2 cell. What happened is, the #2 cell would stay at 60% charge and all the others would reach near 95%. The battery could not balance the cells out. Using the method, in the video, I reduced (discharged) the other 5 cells and then slowly charged up the battery cells together using my iCharger. Also, I might add that my battery was over 6 months old and out of warranty.
Normally when cells start to break down, they will not accept a charge making them unbalanced with the others in the pack. I this case the battery should no longer be used and discarded.
The battery is working perfectly still to this day.
