Mavic 3 Smart Battery Pinout

[Ratatoskr]

Hey there,

I found a efficient mobile Charging Solution for my Thermal Drones. I have powerfull Multi-Channel RC-Chargers and big cost-effective Battery Packs with enough capacity for a whole day of flying. For the Mavic 2 EA i have purchased some cheap Chinese Charging Adapters (without Charger), solder a XT60 plug and go flying.

Because I can't find the Adapters for the M3 standalone without charger, I 3d-printed a prototype by myself.


I found a description of the Mavic 2 Smart Battery (Link). The Pinout of the Mavic 3 is similar, except 8 instead of 10 Pins.
M2EA: - - - - IO CC + + + +
M3T: - - - IO CC + + +

Can anyone who owns a Hanatora or similar parallel Third-Party-Charger measure, if all 3 positive and negative pins are powered, when charging. Or is only one needet?
This would be very helpful for me.

Happy flying

I don't know if it helps, but I have a Yx Intelligent Charger for Mavic 2 batteries, and all 4 positive and negative pins are powered. The same on my Hanatora, all 4 pins powered. So it is likely it's the same with the Mavic 3 battery.

I've successfull build a working Charging Adapter for M3-Batterys. I wired up all 6 Negative/Positive Poles


Now I can charge every battery independently with various currents up to the DJI approved max of 88W (=5A / 1C) and have a Storage program to charge directly to 60%.

Next I will build a Charging Crandle for my big 4Ch Chargers

I made some improvements for better stability and fit to my first Single-Connector and it still working fine.

The 4Ch Charging station is also ready to print:


I will build a first prototype in the next days.

I've been using self-made chargers with Powerpack since the days of mav1 a long time ago.

The DJI battery supports surprisingly fast charging speeds. (130wh, mav 3 battery)

Hi there sorry to bring up this old thread. It seems like applying voltage to the + and - of the battery pins will do however when I tried on one battery the charging will not want to start and the mavic 3 battery leds will not start their lighting pattern when charging. Something I did wrong?

Я вніс деякі вдосконалення для кращої стабільності та підгонки до свого першого Single-Connector, і він все ще працює добре.

Зарядна станція 4Ch також готова до друку:

Найближчими днями я створю перший прототип.

уточніть будь ласка чи виконали роботу? у тебе все вийшло? Чи можете ви поділитися файлом STEP або STL? дякую!
