Hello, I have the following problem, the Ninebot ES2 scooter stopped turning on, the BMS board lights up blue continuously, can you tell me what it could be? Thanks!

i know this video i 2 years old, but i saw that you ha ad 3d printed cable routers/ do you happen to have the download file for that?

I modified the SN according to your method, and the BMS LED blinked blue, indicating no problem. When the motherboard was plugged in and turned on, an error message of 22 appeared. When using Ninebot Flasher to connect and read data, the SN was not modified. I strictly followed the red box in the video to modify it. May I know where the problem occurred

Tony你好 我的ES2 滑板車近一年沒用了 然後再想用的時候發現不能開機 也不能充電（charger綠色燈長亮而電池是沒有任何燈亮）我試過youtube的jumpstart 電池 成功令電池的紅色燈閃爍 但連接charger後仍然未能充電（電池紅色燈繼續閃爍 而charger仍然長亮綠燈）是bms出問題嗎？還是電池電壓太低？

Thank you Tony. I had to learn to dismantle this.

您好，我的es2因為一次不小心手機按到更新韌體後，整個加速變得很溫和，速度一樣都可以到30km，但是到達的時間慢了點，更新前油門壓到底人站在車上是可以打滑衝出去的，但更新完就不會了，請問有辦法降級韌體嗎？我的韌體版本是主控v1.6.4電池1.4.9藍牙1.0.9

I have enough Samsung G30 cells to make a few packs, wondering if the bms needs to be flahsed in some way to read the new 6ah capacity instead of the original 5.1ah

Hi tony can u please help for the love of god? I'm getting an error when i try to read out (everything is connected and soldered just fine) says cant communicate with the tool wrong tool selection or check tool power supply or check that a previous session is closed, check and install rlink driver (which i also done on the start menu)

所以通常跳出故障碼應先檢查是否是油門磁鐵移位了是嗎? 請問有其他方法能聯絡到您嗎?

Any tips on what to check for or fix when getting error code 21?

Como puedo reparar el Bms titila rojo u las celdas esta con voltaje normal

我有个SEGWAY NINEBOT S 平衡车， 其实是GOKART PRO， 现在按电源没有反应，充电也没有反应，反正无法开机，插上充电的时候充电器一直是绿色亮灯。我把电池拆下来， 电池上面的LED灯是蓝色一闪一闪的， 电压测试也是59.4，估计这个电池没问题， 但是我又把电池装回去后，按电源键，就BEEP一下，没有任何其他反应，和断电了一样。请问大概是哪里出问题，谢谢。

my battery had a red light on why?

Hi Tony, I did the entire process of the video without problems, but in the end the blue or red LEDs don't flash

Amazing video Tony! The video was extremely helpful as I had to replace my internal batteries too. Keep up the good content!

Hi can you help me to my es2 ...I woke up this morning my es2 always on and off its so annoying becouse it so noisy I try best to fix it but still on and off

Hello. I replaced the BMS on my es4 internal battery since it wouldn't take a charge anymore and the light was out on the board. New one is installed and now I still have no light, but if I push the button on the bms board, it goes solid blue for about 2 seconds then blinks red for probably 5 seconds and goes out. Are my batteries just no good anymore? Thank you!

Thanks for the tutorial, I have a second hand ninebot es2 that have error 21 and the main board has no error and I think it due too the bms, do you think if I try to flash the bms with this method it might fix it ?

Hi Tony, thanks for guiding us on the repairs. I changed the battery and it was blinking blue, but it continued to give me the same error as before (red wrench display on screen). Would I need to change the computer itself? Or it could be something different? If you have encountered this issue, would you mind guiding me on this? Cheers

Hello, Is the same for the external battery es4? Thanks

I bought a new replacement batt, when i check, it wasn’t flashing blue. Should i return it or i need to charge it first?

Please help. My battery is not charge. The blue led on my old battery flashing like in your replacement battery. I replace a controller and original charger but still no indication of charging. The green led on the charger is always on.

Tony哥，商家给我发错了碟刹装置，如果跟回你的视频然后安装右边行得通吗？？

Hi, thank you for this video. My battery blinks red for some seconds when putting under charge, but then led just goes off. My charger stands near to my friend charger (for xiaomi), maybe i've wrongly tried to use his charger and battery died? What can I do?

Los archivos gracias

Hello, thank you for the video, I have two questions: 1) What exactly can you fix with this method? 2) I have two unbalanced BMS, the cells are perfectly balanced at 3.7 V, but, but i connect the bms and check through an app, the difference between the cells is different. It only happens with those 2 bms, I have a third BMS but it marks the actual values ​​of the cells. Do you have any idea what component may be failing? Thank, I will be grateful for any help you can give me.

Hi Tony. Thanks for the video. I got my battery charged and now it’s solid blue. Measures 42 volts with multimeter. Any suggestions?

This video helped a lot. Thank you. Stupid business here in NYC that sells scooters don't have mechanics that knows how to fix them. They only fix the electric bikes / mopeds.
