I have the same battery and I dropped it t is still good no major damage but I need to see wherever the wires connect to like black one and white one and the little blue and yellow I can't seem to find it anywhere on line
The thin yellow wire goes to the BMS - marked as "TX". The thin blue wire also goes to the BMS - marked as "RX". There is also a small black connector on the BMS with 3 or 4 wires - thin black and white wires. These come from the charging port. Good luck.
Great video! If the cells dies out, would it be possible to change them out, or would that be a hassle as I could see several flat cables from the original BMS wired to the cells?
It could be done I suppose. The balance points could be re-wired onto the BMS if one breaks on the ribbon cable. I suspect it would also be a major hassle to remove the original cells from the holder too ! Also factor in the possibility of the BMS totally locking up if voltage is removed from it.
Hello,i have one error code (E014) on my bike and i can't fix that(i tryed all what i saw on internet). What is master part who i need to change to lost this error code?
Hi I'm having exactly the same issue with my battery. It's from a Carrera bike and I'm tempted to use same solution. I have some doubts about using this method, as I can see you're removing the aftermarket BMS and closing the battery without it. For few uses will be okay but on long term, due to small chemical differences in cells internal resistance you'll end up with different voltages through the pack and nothing to balance them out. Does your bike work with the aftermarket BMS so the original can be removed? That would be the best I believe Thanks for tinkering with that!
I didn't remove the extra BMS (it's there permanently).It should,as far as any BMS can,keep the cells balanced. But the original BMS has to stay because it needs to communicate with the controller. The extra BMS is for charging purposes only.
I would need the whole bike to test a Shimano battery. That's not very practical given our respective locations. But I have a spare battery for you to try if you're interested. If you want,send me an email - garethem1@sky.com
I have exactly the same battery with the same problem , could you fix it? I think I’m local to you, judging by the phone number on the estate agent sign at the end of the video :)

Will it also work without the communication cables? Had many bikes where a communication wire was installed but it was not used at all. Enjoy the kebab👍🏽
I very much doubt if the system would work without the communication . If this was my bike,I would try it;but it's for a customer. Thanks for the suggestion,and looking forward to a proper kebab .............
I can't see any for sale online. It's extremely doubtful that Shimano would sell spare parts for their batteries. You would probably have to replace it with a different 4 pin connector (rated for 30 amps for positive & negative power leads). And change the charger connector to suit. Good luck ...........

Thanks for the video. Weird dat shimano manage battery level in cells like this as the bms is the weakest link which we cannot replace ourselves.
Great video! If the cells dies out, would it be possible to change them out, or would that be a hassle as I could see several flat cables from the original BMS wired to the cells?

Awesome fix. Did you have to modify much to fit the bms inside.
Thanks
I haven't finished it yet (hence the part 1 in the title).
Hopefully , I can fit the BMS somewhere.
Look out for the part 2 ............

HI, thanks for posting.. can you tell me what the cell voltage is at cutoff at full charge.. 3.2V to 4.2V ?
Each cell group will be at 4.1 - 4.2 volts when fully charged.

Can u give me a link or models for the extra bms wich u putted or any extra info that gonna help us and the tiny chip too
It's an ordinary 10S BMS.
You can find them on ebay etc.
Which "tiny chip" do you mean ? The fuse ?
I bypassed the fuse.
et quel informations sort des fils jaune et bleu
Probably digital information (packet data ?)

If you remove the switch and gauge unit,it may not work again.
Or how can i connect the wire to the on off switch
