You may check DHL, fedex or UPS costs and requirements for a 1kg Lithium battery 20x20x20cm. Last I checked around 150USD, while the whole battery itself will cost around another 170USD from Malaysia. If it’s still feasible to you, feel free to PM me and I will directly connect you to the maker...

Actually you may not be increasing battery temperature. https://mavicpilots.com/threads/mavic-air-2-extended-capacity-battery-mod-7350mah-not-my-work.95910/ I didn't measure the battery temp, but the current draw increases from around 7A to 10A, measured via flight recorder. At the same time...

for sure it spins your motors more to create equal amount of lift and thrust due to increased weight. but i have a similar one and yes it runs ok. i think i have done 20 flights exceeding 30minutes and have not encountered any mishap whatsoever. but i do take extra caution against wind, i never...

Did you try and plead with him to allow a one time fee access? Or a few day access? That was what he propose for me the last time. Did you also ask whether the CP2112 is enough? I never got around to asking about this. Perhaps CP2112 + TRB short license if feasible is the least painful...

the stock battery is 3S. Please, don't mess with the battery unless you are sure what you are doing. Of course losing a drone can be no big deal.

By the way, if you did get the CP2112 USB adapter, perhaps you can contact this guy : https://trb.patboonlab.co/products I'm not completely sure but I think there is a possibility to use his software to fully unlock the bms and gets you the ability to reprogram the battery capacity. Last...

nice, its a bummer that it will not learn or adapt to new capacity but that can only be expected. as a vendor i will not program my bms to do so, as there is no economical interest. as i can summarize as of today, 17 July 2022, you'd still need a password to unlock the bms to rewrite the...

i am skeptical (simply because DJI implements too many locks on its batteries for good or bad), but always open to new things...let us know!

you know what you are doing so I'm very glad to meet you! In my country I just have to send my pack and USD80 for a rework / modification to double the capacity with full capacity rewrite. Its so convenient that I neglect to do any more handiwork...

You are right practically at extremely high loads the higher voltage battery would probably NOT charge the lower voltage battery...I suppose I was exaggerating. You cannot totally ignore Ohm's law : Higher potential difference will always flow current, even if one is 11.2 and one more is 11.1...

But you started with only 92% with the smaller external battery….? So there could be a bit more juice in there no? Another thing to note when using external 3s packs is that they are now in parallel to the original 3s battery inside, and it is never a great idea to connect in this way. This is...

you are right, thanks for pointing out. I'm very supportive of self regulation rather than corporate 3rd party regulation.

at some point after 10-20 flights of 40mins or more you realize its pretty exhausting to pay so much intense attention for so long. I know I used to race RC cars and at full pelt, the battery pack only used to last 5mins or so. I can tell you if I was really competing it drained the crap out of...

I'm so sorry I havent checked back to this thread for so long. Do you still need help? If you are using genuine battery cells from DJI, and all 6 cells are individually charged to maximum voltage and capacity, you will get extended flight time from the combination. However, in a nutshell that is...

Hi, and welcome...Thanks for your teaching. Yes, I'd very much be interested to have the parts and used and the SW. can you link them out?
