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.

Great video, my friend. I'm watching you directly from Brazil and following your channel.

Great vid. I like the way you use common sense and advise only people that are familiar with this stuff do this. Also, more common sense, if not comfortable doing this mod, just buy more batts as DJI makes a good product. Just very well said. Subscribed/Liked already.. Will watch the rest of the vid now.. Pls Carry on.

[@willalexbombraga7807]

Good night Zolly when you took the epoxy and took off the solder, this is to not block the battery, correct. Success on your channel.

[@JAKOB1977]

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

[@hallio111]

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...

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

[@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

[@ZollyD]

Correct.

[@salt5523]

How much for the extended bat mod? You put in description to message you on facebook which i did

[@yuriyboyun2932]

[@arnur8510]

do bms need extra batteries?

[@ZollyD]

I am not sure that I understand your question. But no additional batteries are needed for the BMS itself.

[@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

[@fluidmind3629]

will cells from dji mini 3 (3850mah)fit in mini 2 ... ? without battery case

[@raymondtremblay7656]

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

[@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.

[@tennis5126]

Great stuff. Just a question about charging - can i charge both batteries if I connect through the drone usb-c terminal? Also, will fast charge work with the lipo battery?

Yes it works great and fast charging works too. That is how I use it.
