Besides Is there some logger and decoder for dji messages? I have all wires accessibly in my setup, so I can peek a little. m2p

Thats awesome! So youre running 2x18650/21700 Liion cells with the stock BMS or did you find one to use in its place? Does it still behave like a stock battery in the App and on the Drone for RTH and all that? Cool work! I love my Mini 3 Pro!!

How is the run time with this setup vs the stock battery?

Thanks 2x 21700 6000mAh vapcell, total weight about 150g BMS from not original battery plus. It behave like stock battery. Drone weight was slightly reduced. With these batteries it is roughly the same as a standard drone with a plus battery. Flight time is not satisfactory, it is about 40 minutes to 3V per cell. Due to large sag I can use only about 4.6Ah from battery. And power capacity (Wh) is lower than with LiPo battery. Typical discharge curves [here](https://budgetlightforum.com/t/bench-test-results-vapcell-f60-12-5a-6000mah-21700/222498

Looking for alternative batteries.
