waterdamaged mavic air 1 , need battery pinout

[robcampie]

i have a water damaged drone, got it to tinker with, only comes without battery.
Now i have opened it up, seen a lot of corrosion and decided it needed a good ultrasonic bath with demineralised water and isopropyl alcohol.
After that i dried the mainboard and placed it back into the air.

now i needed to test it, so i put 12v on pin 3-4 and the pins at the right 2 form the end.

the drone powered on, fan made a lot of noise. but no wifi signal.

I was wondering, is it possible to power the drone without a genuine battery?
i know sometimes the pins all have a purpose, and so i thought maybe there is hope when i try to power it with a genuine battery.

Would like to hear from someone who can send me in right direction.

And it would be cool to find a solution for these crazy expensive batterys

Hello from the Hoosier Heartland robcampie.

I found this page that has the pinout for The Spark, Mini 1, 2, and the Air 1.

Add here any information about DJI batteries.

Thanks. Do you think the board utilizes the 3.8v from single cells?

Beats me. ?

I'm not a battery expert.

This post discussing a Mavic Air battery may shed some light.

Mavic Air Batteries

According to the specs on the back casing of the battery, these are 3 cell LiHV batteries. (LiHV or HVLi = High Voltage Lithium Polymer) LiHV can be charged to 4.35v per cell vs. standard LiPo's 4.2V (Nominal Voltages per cell are 3.85 and 3.7V respectively as well) I know there are a ton of B6...

No sir, battery provided 12 v as per the pin configuration. But I think the pc setup has a function to inform the drone about non OEM battery. You maybe need to enable that.

Dji Mavic Air batteries have authentication check with a drone over communication port.
The drone could be powered up from hobby 3S LiPoHV battery but it will not allow to take-off. Dji Go 4 will pop-up 'authentication failure' warning.
To let it start the motors, one should enable 'non-DJI' battery option in engineering settings through the older Dji Assistent 2 which has hidden debugging menu.
