Amazing! But you are a rare exception to be able to do this. In my opinion machines like this with non-replaceable batteries should be banned. My Bosch Athlet has a dead battery after just 2 years. The rest is still in new condition. A scandal for the customer and the planet. Bosch should be ashamed of itself.
Great video. Thank you! 👍 Smart battery design by Bosch by the way.. 😁😁😁 I mean..yeah..cost effective..no problem to repair.. Explains the variety of models and voltages :-))
Hello. I have the same problem as you. I open the vacuum and test all the cells, one of them have 3.4v and the others 4 v. Quit the cell from pack and recharge it with a lipo balancer. Now all the cells are in 4v, but the vacuum don't works. No lights, no sound, nothing. Maybe this vacuum have a mechanism or something don't let change the battery easily. Anyone live the same? How I relive my vacuum? Thanks for your video.
There I another video. In the comments there is a guy who talks about replacing the bosch board with a 7s BMS and doing away with the junk bosch controler

People who design this kind of junk should be punished. :(
Great video. Thank you! 👍

You’re welcome
Thanks, could you please advise which battery you bought, with protection or not?
samsung 3000mAh 20A, no protection for batteries, vacuum cleaner have protection parts I think
請問你用的是甚麼焊機？ 與一般電烙有何分別？
用了兩種焊機；
一部是點焊機，給鋰電池上金屬片用，好處是比較低温和快捷。鋰電池接觸點正極本身有高温保護，如果長時間高温的話會損壞鋰電池，用一般焊機要眼明手快。
另一個氣體焊錫筆，與一船焊錫槍同一原理，只不過不是用電，而是用氣體。
過程拍得好清楚，多謝分享
家中只有舊式筆型（辣雞）焊機，沒有點焊機，請問焊接時有什麼地方要注意？感謝
用辣雞要快手啲，鋰電唔可以過熱，過熱粒電有機會會報廢，盡量小心唔好熱溶鋰電外殼保護膠，熱溶左嘅話一定要包返好佢，唔係好易短路。
同埋一定要落松香，唔係上唔到錫落個接點到。
我看到你的修理過程十分佩服，我也有一部Bosch 2in1 的吸麈機可否代為修理？

Hi! I have a same problem. Did you solve it?
No. I decided it was dead. I haven't idea how to reprogram the EEPROM. Sorry

換了電池，但差滿後，用2，3分就無電。請問是否電池焊接時死了？
有可能管理電池塊低板壞左。。。不過有兩個方面你可以去查下：
電池係咪大輸出電池,
會唔會焊接時候出錯。
如果拆出黎用電錶度，有部分電池扯到得0V，咁好大機會個電子板壞左
@greg93712 thank you.
看完了，感觉好难，自己不会弄。
嗯，如果你有diy的話，應該可以的
Почему плата в блокировку не ушла??!
Абсолютно согласен с вопросом. Питание не снял, стал отдирать провода в BMS - всё, прошивка должна была слететь. Мутный видос.
А что если новый чип bq77pl900 впаять он запустится? В даташите не нашёл пункта про специальную блокировку
我今日部機又係依個問題，唔知點算
換新機最方便。。。
dude has playing copyrighted music in background and got all the audio in video muted by youtube. lmao
Far too complicated
I just try my best and enjoy the process.
Fck it, I bought a new one, Chinese manufacturer and the battery is easily replaceable.
😂
which one did you get?
@@paulbrowne6087 Dreame T20 25.2 V
what do you weld it with?
