DJI Phantom 4 - Battery reset and what's inside the case

What is inside of the DJI Phanton 4 battery and what I have learned about resetting a battery. The down side is you have to access the battery mother board either through making a hole in the case or opening the case itself.


Once you have access to the board you will need to touch the ground and reset contact (RST), hold it for aleast a few seconds the release. The leds should flash and the battery will turn on. This has only worked for me so far on a battery that would not show any lights when the button was pushed. I did check and the battery had power but the board was unresponsive. Still trying to solve the led 1 flashing issue.


Hope this can help some of you all out there.
