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.



Good luck and welcome to the Forum. :cool:

Beats me. ?

I'm not a battery expert.

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


 
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.
