The red paper is just a water contact indicator - does not have any electronic impact. I had the same issue with a phantom 3- quick water contact killed the battery. I'm gonna open up the P3 battery and I'll let you know what I found.
My theory is either the water reset the MCU or they have traces that detect the electrolytic presence of water. Once that happens it either goes into EOL mode or factory mode and waits for commands or has to be reflashed.
The battery bios chip don't lose the program. Whit water 2 things. 1 broke resistor or sham thing. 2 Brock the batery chip its like prossesor whit ram the cost its 3 or 4 euro same like bios laptop but the program???? This is problem. But no broken eazy perhaps something near its broke I hope. But your mind it's very clever ☺️sory for my English
If it turns on and acts as if it's fully charged but does not power the drone, could be in permenant fail mode and needs reprogramming with the EV2300 module and special software. You still have the board?
My guess: At 7:20 it looks like there are some mosfet on the board. To my experience they die in contact with water. Maybe they are used to control the main power circuit.
You may have already found this but that red dot (near the -ve terminal) indicates that it has come in contact with water...some circuit breaker blows and that's it...can you check whats wired up to that?
I never knew that. I just looked at the board and scraped the 'paper' off. Under that was a thin plastic film with adhesive. I can not see anything underneath it on the board.
Thats just DJI pulling an Apple. Might be a replaceable fuse, more likely software suicide when water is detected. Might be a hackable firmware fix sometime. Keep the cells if they are fine. You can relife batterys with a single cell failed. Go and get a Powerextra battery instead and avoid DJI's programmed obsolescence.
The 101 it's fuse.... Down its pin ground this is - check the + in and out to chip its power controller perhaps. Google the code chip and you see the input and output chip. check resistor and mosfet near the chip 101. The black it's resistor the white it's capacitor the resistor meter om put the - to police terminal and start to meter ☺️...... The code po1438. 07 like same motherboard laptop code if Google and find something bock diagram or power diagram it's help. Sorry for my English.
What many people don't realize is that Lithium is very unstable and can explode in a fireball that is nearly identical to a magnesium fire. Be wise and don't be cheap when your life is involved. One mistake could burn you badly, or burn down your garage or home.

Perhaps it's secret reset.. Many products it's has and knows only the service end person like you to looking solution ☺️

I no longer have the board nor the battery.
thanks for your video

You're probably right.

Is it possible phantom 4 battery can be reset its cycle?
I think there is an electronic component that burns out and needs to be replaced. I never was able to salvage this battery.
Dont throw it away, i want it.
I ended up stripping it down and making a power pack out of it.
about it, we have , if want, pls contact with me

Water damage the stickers pink or red definitely not white as it should be
