For anyone else who got a little too excited at the title, ECC here is error correction codes, not elliptic curve crypto.
Very cool writeup, thanks for digging into all those data sheets and sharing it with us! I feel like the hands-on electronics stuff has always been a little bit inaccessible to me, but posts like these always make me a little more excited to start doing little projects myself. So thanks for posting.

Please not. Bike thieves are already annoying as they are (a ring in the rural city I live in managed to steal over 400 k€ worth of bikes in a matter of months, in my case they only stole the control unit), and so are people modding their bikes to run (way) faster than the legal limit, leading to more and more calls for them being banned off of normal bike tracks.
Damn, I really enjoyed reading this. Great writeup!

Fantastic and inspiring write up, big thanks!

We do it at https://infinite-battery.com :) our battery is compatible with Gen2/Gen3/Gen4 (we haven't yet tested on smart systems though)

Be the change you want to see in the world.
What a beautiful write-up! This is such a lovely resource for anyone who ever has the curiosity of "I'm interested in getting a firmware dump".
Drane Hacking next: bypassing Radio Electronic Warfare.
Now do DJI next
And as usual... something that looks like it uses Linux, but has absolutely zero Google search results on how to obtain the GPL sources.
We desperately need some large ass legal fund that takes the GPL violators to court.
