Flew yeswterday Mavic and due to unplanned delays the battery went to a critically low level. Let it cool then tried to recharge. No luck. Red light on the bank. Battery button shows two green solid and the third flashes. Then the light extinguishes.The battery wont power up the machine, either.
Any ideas to reset/ salvage this battery?
