Great work! Thank you so much. I watched the whole thing and I listened carefully, but I did not hear you say anything about ensuring that the original cells are at very nearly the same voltage as the new cells when you connect them in parallel.

Well done.. thorough and to the point...like it the thing in the box is a Mavic Air2.. so you can spoil us with a Mavic air 2 with interesting projects. :P though do have one of these 4USD thin plastic bendable ribbons for Mavic Air2... you simply lay it on the pads., and then plug the battery in like normal and it will make a connection and give you an XT60 socket on top for normal batteries. the more or less the same approach, but so thin that it can lay in between the crease when the battery is connected.

So howanu volts can the mini 2 take before it fries? What volt does it come out at from the factory? The volts is what I worry about. Idc to destroy a mini 1 battery attempting this but I don't want to throw too many volts to the mini 2 itself and fry the computer board

[@robertlee8400]

You do know that DJI just updated their battery’s as of January of 2023 right & you can also go into settings & fix the discharge problem now also , all you have to do is put each battery in the drone & download the update from your phone to the battery in the drone , one by one , now you won’t have this problem & you,ll get the best flight time for your buck .

Welcome back! This is a Great mod and we may use it with our attachable wing which can carry additional weight. Do you know if you can swap the original battery by using temporary jumpers from another battery to retain voltage during the swap? Also, do you need TRB for proper telemetry if you can swap to a higher mAh battery?

[@user-ox6uk4ec1i]

Good afternoon dear Zolly! I have a very important question, please write an answer. You can repackage the regular battery from DJi mini 2 and solder it to a 3500 mah battery without locking the battery. I watched a video on KZbin from other users it didn't work out. Will you be able to post such a video? I will be much grateful to you sincerely Leonid Anatolyevich

[@ZollyD]

You have to check the channel "The Longranger". He has the solution that works. Unfortunately to replace the cells you need to reprogram the chip on the board.

[@voodoo2110]

Я думаю что блокировка срабатывает тупо при обрыве питания (при отрезании заводских ячеек). Если обеспечить временные дополнительные линии питания с других ячеек, то можно пересобрать батарейку на другие ячейки без блокировки BMS.. ну это так - рассуждения. Естественно, в прошивке батарейки останется старая ёмкость, но время полета всё-равно увеличится

[@dronardo]

Hi Zolly! Great video! It is possible to Change the cells instead of adding more cells? I mean, to do it as you showed with the mavic mini 1. I was thinking of upgrading the cells but not sure if possible. Thank you again for your videos!.

It is not possible without a special software which I do not have. For DIY solution on the Mini2 this is the best.

1:20 could you solder on those terminals if you remove the nickel strips , and working on the pads with sandpaper to make it solerable, or is this not possible? thinking about changing my mini3 battery to 21700s... what I've noticed, is that there are 2 copper like pads /strips, I wasn't able to solder to these strips, at least not easily, but the other 2 strips seem so be solderable, at least on the nickel strips...

[@romeosiera5188]

👍👍👍 I have question, 3500mAh means: 1.Total batt. capacity (The original DJI 2250mAh + External batt (1250mAh) ? 2. Or only external batt. So total 2250+3500=5750mAh ? Thank you.🙏

[@salt5523]

If you extend the batteries they are connected in parallel right as they arent in series so this shouldnt change the voltage just the amp hours? So basically its a game of figuring out the best power to weight ratio

Correct.

I recognize these battery cells from a phantom 3 drone...as well as the Mavic Air.

[@ZollyD]

Correct.

[@philldownes8685]

witha second battery the same capacity as the one inside i would of expected almost twice the flight time. you have gone from 2250 and added a 2375 is should be double the time minus a bit of time loss due to extra weight,,,, the plus 4480 battery being very heavy is going to be not so good, but should be atleast twice the normal time... what it needs for a good test is just the 4480 battery on its own, then i think you will see around 45 mins plus..

Have been wondering this very same thing. Only one way to find out.

[@sahilsharma1985]

are you able to do long range test with your best mod :)))

[@lordymorty6024]

I wonder if 3500mAh is the optimum battery size or do you think 3000mAh would actually be a little better due to the weight difference. Also, how much weight reduction do you think could actually be done to the drone without actually impacting performance?

[@vladkedrov8901]

The drone itself is already as light as possible, with ultra light plastic and everything. It is so light that you won’t be able to reduce much weight from it. And even if you take all the covers off, you won’t be able to reduce enough weight to make it worth it. Engineers at dji are not stupid, and if they could, they would make it even lighter.

[@aliitaly4374]

is so good test .. how much the total weight for each , if you know that or remember it?

[@alexko2877]

Hi Zolly and all, can you or someone clarify please: it was said that to fly such time you need to charge batteries to 4.4x2 = 8.8v, which requires a "trick", since Imax B6 can't do it and on the same time, Zolly showed that batteries were discharged to 6v prior the "levitation". Can somebody say at what level the additional 3500mah battery should be charged to achieve same results in flying time Zolly has achieved in this video?

[@ZollyD]

4.35V per cell so 8.7 V for the pack on the top

[@dereksynkopa1822]

Hello Zolly. Thank you for your interesting tests. I also have experience. I noticed that you drained your batteries to 6V for the test. The capacity is then 3.5Ah. In practice, the drone will turn off at 7V. The available capacity will therefore be less. Maybe that's why the original 2250mAh batteries are around 2000mAh. One more thing. Tell me what voltage did the external batteries discharge during levitation?

[@ZollyD]

Yes, that is correct! :) When I disable the battery voltage monitoring system, the drone can do an additional 3-5 minutes, but after that it starts a rapid descent due to lack of power and if it is coming from high enough, not even the ground effect can save it from crashing. So that is why it is not included in this video. I think that is why DJI implemented the 7V limit as well, as the LiPo discharge curve breaks down at around that voltage sharp. Like this there is a bit margin for safe landing. The voltage on the the external cells was 7.15 V. (That is due to to the drop on the cables)

[@sousarogers]

Please confirm so you have one wire weld it to the positive of the original battery and two wires welded on the negatives at the original battery is that correct

[@aeiou9755]

mh what ist with the normal 21700 cells with 5000mah - they are a little to big for the rear. but can we make with a 3d printer a new top backside that this fit in ? than we have 10 000 mah on the mini / mini 2

[@yjtang1]

Hi Zolly, really great job! Please keep it up! You mentioned that the B6AC was only able to charge your additonal battery to 4.2x2 = 8.4v and you had to charge it with "additional power supply" to 4.4x2 = 8.8v. Could you please make a separate video about that? It will help a lot!! Thanks!
