what was wrong with your scooter? Mine is not charging and it doesn't turn on. Sometimes I can turn it on when I plug the charger for just the time of turning it on, then I can use it until I turn it off and the problem repeats. Do you think that changing the BMS board could fix this problem? Thanks for the reply.
Здравствуйте. Подскажите, если не затруднит. На выходе с BMS 20В. На входе 40 как положено. Решил поменять BMS. Но на выходе всё те же 20В. При нажатии на reset на плате загорается синий(не мигает а горит). Затем тухнет и начинает мигать красный и тоже тухнет. Возможно вы знаете, что может значить эта индикация или где это можно узнать. Благодарю.
Еще вопрос, можно ли установить эту батарею на электровелосипед не меняя БМС? Если родная БМС не подкючена к контролеру от xiaomi будет ли работать батарея?
Have an m365 that I buyed, and the battery doesn't charge, checker the charging port but there's not any problem, I think it comes from the battery or the BMS, there was a solder that has been soldered with tin, is it because of that?
recently i had a client with same error, but it has red LED error, not charging and not switching on. So i replaced the BMS and the charging still not active but at least it works.. i didn't solved the problem in my case, usually i get a faulty BMS, replace and all working... Check all solder joint because if you solder in a wrong way this could cause also an error... and the cheapest option is a new BMS...
@@RMFUNTIK the battery have like 4 soldered joint that are soldered with tin, but I don't really think it comes from that, I'll try replacing the BMS and see if it'll work
Hi, after changing bms it does not output anything but when I connect it to charger and press the button on board it flashes 1time red then 4 times red and blue simultaneously and after that 4 times red, any idea what could be wrong?
Подскажи плиз, у меня плата BMS с одним предохранителем, в интернете нашел плату с двумя предохранителями, если я данный "апгрейд" сделаю, у меня всё работать будет?
Смотря что у тебя сдохла на плате, я вообще ещё не встречал дохлый предохранитель, дохнет что-то другое и пока я не могу сказать что, мне дешевле поменять всю плату целиком.
@@RMFUNTIK нет, у меня вс работает. Просто прочел, что если убрать лимит скорости то БМС плата с одним предохранителем сгорает. Вот и подумал заменить свою на плату с двумя если возможно
@@daveelhansom9575 ты ведь понимаешь, что предохранитель это просто небольшой замочек, чтобы не выгорела вся плата... От их количества ничего не поменяется, все равно прогорит, поменять то можешь, только толку никакого. Единственное, что можно поменять на ревизию по новое. Но я бы не стал трогать, работает и работает.

Thank you, very helpful video. I tried to do everything as you explained. But my m365 non charging. Bms is flashing blue. Voltage values seems correct. I can connect scooter and use it. But it doesn’t charge. Now battery level is 72% :( what can be the problem I tried everything. I cry nervously😢😢
@@RMFUNTIK First of all, thank you very much for your answer. I was very busy on weekdays but now I was able to measure voltage. I measure the jack that comes out of the charging port where we plug the charge cable to 40.6, and the thick red black cable from the BMS is 39.0. I added the pictures to google drive, you can check from there. Thanks again. drive.google.com/drive/folders/1Dn2ON9SRC6JwGcj3zBg0o8wtGNnXAyeQ?usp=sharing
@@BatuhanAltun hmm.. seems everything is ok... did you try charging on 72%? because you can't charge if the battery is 100% it won't allow. please check everything several times, check the wire from charging port to battery block all the way, connect everything, connect charger and measure where it connect's on BMS... hope you understood. Check the wire connection (solder point) on BMS. maybe solder point is broken, re-solder...
Check each cell ( simplest way in app, or measure on battery). I think Your battery cells is not balanced. If i have right try to dischsrge battery to 50% and then try charge
@@KazikFurmanczyk it's always sparking when you connect it to the motherboard, try rebooting your bms with that little button, hold it like in the video ending part. if not, then you did something wrong... check all the wires and solder spots
What order did you connect?
1st-balancing
2nd- positive
3rd - negative?
in what order? well it's really doesn't matter i guess... but if you wan't to do it properly.
1. bms.
2. ground.
3. positive.
Great video very helpful ,thank you
Thanks 👌

you should check the voltage, then inspect the joints (they fall off sometimes)
@@RMFUNTIK everything is ok. It works fine once you manage to turn it on. My only problem is that I can't turn it on without plugging the charger
@@aslogd.o.o.543 maybe upper BLE board ? check your ble button.
@@RMFUNTIK thank you very much for your fast replys. I don't understand what you mean. What is the "ble button"?
@@aslogd.o.o.543 button that turn on and off the scooter...
Where did you buy the new BMS? The one I bought did not have the 5-wire connector soldered on and I'm wondering if yours came like that?
china version don't any wires in some cases, with the wires it's a bit expensive one's, but from china to. Original costs 90 bucks
Hi, i changed the motherboard, but the led screen still doesn't start. Is the problem with dashboard or bms sircuit board?
Thanks
there is button on the bms, press it to reset. (long press) it should flash blue led.

проверяй все контакты, может не првильно спаял? может дефектная BMS плата?
Hello,
Which type of silicone did you used?
Thanks

what LED is flashing on BMS? and what is the output from battery voltage?

check the fuses, broken solder joints on battery cells, if it's ok. probably need to change bms
Скажи пожалуйста а эти две длиные полоски которые подсоединяются в BMS какую функцию выполняют?
Какие длинные полоски? На ячейки ?
@@RMFUNTIK да на ячейки, это наверное балансировочные провода?
@@Metrowhite это соединениющие элементы идущие на bms контроллер, честно незнаю как правильно назвать
I think you need a hotter soldering iron.
To dangerous, because you can damage the battery

Every BMS from ebay lacks Z fuses?
cant we find a bms with them?
eBay's bms's don't have fuses instead they have those metal plates. Original bms will costs around 100 euros. So.. I would stick to eBay's :)
@@RMFUNTIK what are the disadvantages of not having zfuses on your BMS?
@@KazikFurmanczyk if you fuse are not going down, the whole bms does boom 👌😂
@@RMFUNTIK i just soldered everything and after connecting it i had a spark and now its red light all over again... i must have missed something
