Hello. I have bh atom x bike. Brose motor. I want to use specialized battery for it.
I have one but it is blocked.
This battery's have two boards. When I conect them - they don't start.
When I give 3.7 v to the border with mcu it start but show 0 percent.
The brose morot battery has 6 connectors.
Blu and green - flash
Black and red - power.
And do you know for what are yellow and brown?

Also has anybody already seen this video.
In this video man has brose motor , display from my bike bh atom x and he made some kind of battery emulator.
With this bord you can use any battery with brose system.
In internet there are such words for Yamaha and bosh protocols

The battery worked fine for 2 days after we bought it second hand... then on the third ride bike turned off after approx 6 km ... after being off for one hour .. it turned itself on again ... the capacity was as before. Now that repeats every ride.That would be me
How long ago it manifested this symptom? Prior to that event, were there any concerning signs? (eg. capacity loss, interruptions when low state of charge). Does the TCU turn on or not?
Ok, so it works intermittently. And you got the 3rd led blinking when you try to charge it?
Also, how many cycles? You said you bought it second hand. Any signs of case opening? Did you wash your bike with high pressure water ?
The fact that it's still powers on is a good sign. But in order to know more, we need to have physical access to the battery. Let me know if you want to send it to our workshop for a complete diagnostic/repair.

If the cells reach 0v, you can safely dispose them, do not try to charge them or it might end up messy
Assuming the other banks are good (balanced with max delta of 20-30mV), you can try to replace the 3 faulty banks with same cell type. But if the rest of the battery cells are used (lower capacity) their voltage will deviate from the new banks and BMS will give an error.
Also, even if you replace all the cells, you need to unlock the BMS in order to used it again.
I would say the only reliable solution is to replace all the cells.
