The control board is held to the lower battery housing by two screws. They're in the gap between the board and the edge of the case, right above the battery connector
Glad I found this. Thank you for taking the time to rip it apart and showing us the gizzards. I was considering fixing my dead battery but it seems to me that given the way that it is assembled it's just not worth the effort in my case.
Im glad you made this video man, good information you saved me a few hours at the bench. i for sure was looking for a way to change out the battery because of the price. i have 3 old batteries i was going to use if i could. good video i also think the suspense of actual time breaking open the case was the best lol
they did sale the cell to replace for m2p and zoom. the cell is 4000ma , 0.5mm thicker and i did trying last summer.it's working like a champ, no any error or cutoff at 2%, charging a little bit longertime than oem ,but just for fun , im not risk my drone for just $150. Thank you for videos
At first I thought, look at the date of the published video, 1 April. But I got past that & watched more. Fascinating, thrilling and I just kept thinking, do you have life insurance? Thank you for sharing, very useful 🙏
Cool video, thank you for that. I hate DJI for this, my battery cells are fully okay, but the connection board seemed to had a problem and did not send aymore battery data to the drone. They did not replaced them. But now I have a extendet torch battery ;D
JUST A CORRECTION, YOU SHOULD NEVER RUN DOWN A LITHIUM BATTERY TO ZERO, THAT IS WHY YOU HAVE A BMS, TO PREVENT OVER CHARGING BUT ALSO NOT TO ALLOW IT TO DISCHARGE FULLY. ALSO YOU DON'T CUT AND SOLDER, THE HEAT WILL DAMAGE THE CELL, YOU CAN GET MINI SPOT WELDERS BUT SEE VIDEOS ON TH-cam ABOUT BAD DESIGNS. I THINK YOU PROVED THAT ON THIS MODEL IT IS EASIER TO GET A REPLACEMENT ON AMAZON.
Very interesting video... I have some information.. the guy that makes the modded mavic 2 pro batteries uses the newer imprived cells from the air 2 batteries.. also I've heard once the smart controller in the battery loses power it is ruined so power must be connected at all times to that.. the guy that mods the battery makes them higher capacity and puts them in a bigger custom plastic case.. he also reprogram the smart controller for the added capacity. In your case here if you bought air 2 batteries to canabolize and could keep power to that smart controller you could probably make some improved m2 batteries at a similar capacity. Would it be worth it.. that's the question.
Yeah, I found this: www.eevblog.com/forum/chat/experiences-with-ti-bq-management-ics-when-revelling-laptop-batteries/ Which is a shame, cause I found your comment after cutting my battery wires... Oh well. I expected I'd need a new battery anyway, but it was good to learn about the BQ chips
Would you still bring the battery into dji to be repaired ? I got a message come up on the screen of my SC to take the battery into dji to get fixed can dji repair these batteries or should I just buy a new one
If the battery is still under warranty you could send it for replacement, however they will not replace or repair batteries that are out of warranty. I don't recommend throwing it away yet, because if there is a factory recall on them, they are required to exchange all defective batteries regardless of the warranty status.
@@luciferbox5577 Oh ok, I figured it is too risky to use a repaired and unreliable battery on a thousand-dollar drone, so I stopped any repair attempts.
@@TECHNOLOGYTIPS101 Personally, I agree with you. It's not something I would consider doing. Unfortunately, we just have to spend our hard earned cash on the proper ones.

Too bad the battery packs are welded together and not soldered together, so you need a spot welder to replace them.

I agree, it is not worth taking the risk of loosing an expensive drone due to a battery failure.

Great information, Thank you
Thanks man for showing what's inside the batter. i have 3 batteries that are bloated. they charge but unreliable to fly
No problem 👍
You can source lion pouches with a similar form factor, the absolute Wh figure doesn’t need to match exactly.
Thank you
When I saw that you disassembling fully charge battery and you put your hair in frame at 6:19- I thought it starts smoking and explode now. Gosh...😂
I agree, this was one of the most dangerous things I ever did, and I will never take such risks again.
Amazing explanation, thanks 🙏 definitely now I change my view of what to o with my battery
You're very welcome!

so i`ts locked and you have to unlock it
Tear down was nice, info is helpful
I have a DJI mavic pro
Glad it was helpful!
Those battery cells are $4 each on Ali express. Well worth redoing yourself. Worst case you ruin an already ruined battery and it costs you $16.
Thanks for the tip, I did search but I couldn't find them on Aliexpress

I agree, it is too risky to repair it. I finally ended up getting a new one which also started to swell after a year and maybe hundred charges :'-(
i liked this vid purely for the fancy nails :) that and opening shit the same way i do... precision brute force :)
LOL!!!

@@TECHNOLOGYTIPS101 yes. I'd love to see it..

once is loses power can be reprogrammed, is not bricked forever.
My battery is fine except for a bulge in the plastic under the plastic is a space. The plastic is warped
That is very dangerous, watch this video to see why, th-cam.com/video/cRosUjUYO_o/w-d-xo.html

There is no way I would rebuild a battery for my DJI pro 2 I would rather pay the 150
I agree, it is not worth risking your drone falling from the sky.
FYI DJI will replace these free!!!
Thanks for the info
Have you seen the video on here by Bikesh Sethrah?
Do you have a link to that video?
AliExpress stocks replacement batteries
Indeed, and so does eBay.
carefully and uses a knife lol
It was a very dull knife, nothing sharp to hurt me, but nice catch lol
That should be Bikesh Shresthah.
Not yet, but I would love to watch it if you could send me a link
