I have one here now that i am about to try to open, but is it really T9? Is it torx with a pin in the center? Hard to see in the hole. Feels like not even T10. Does not fit perfectly, and on one screw it does not fit at all. And looks like something in the middle. BTW, symptom om the battery: Bike do not recognize it. Charger flashes orange a few times then nothing. Battery level shows four lights.
Greetings. I have a Question. Is it possible to remove the lithium ion batteries and replace them without causing any software issues with the Motherboard?
Shiiiiieeet, i know that feeling when you broke it and the customer will be sad and you are sad so everyone else is sad because of a sad shimano battery, a really sad moment.
This comment makes me sad. But we will try again until we succeed! Bosch systems have been cracked by several companies and when shimano steps gets big enough Emond marked batteries will be on the market. They are not electronics experts like bosch so i suspect it will be easier to crack then bosch.
I have shimano Down Tube Battery STEPS BT-E8016 630Wh. It Light says it is too Hot but no, it is not . Is there possibility to repair heat sensors ,i think they are in other side of battery ,easy to remove.
Bonjour Existe t' il un logiciel Shimano pour déverrouiller le bms svp. Si tu change les cellules le bms ne repart pas. Merci beaucoup pour votre aide.
Hej! Vi har ett sånt här batteri som laddats 1 enda gång och sedan kom pandemin så den laddades inte på något år. När jag försöker ladda batteriet så händer inget, dvs det laddas inte. Observera, batteriet var helt nytt när det hände- cykeln kanske användes 2 timmar. Vad har ni för förslag, är det något med att man behöver reseta denna tro? Tack på förhnand
Has anyone ever tried pulling cells (and changing the series/parallel if needed) to make a lighter-weight / shorter-run battery? I tend to use my eBike as a "lunch ride enduro" machine - I give myself a slight boost up the mountain and then let gravity send my back down. I'd love to have an alternate sub-2lb STEPS battery, and I am not afraid to solder a board, but I don't want to spend 4 months fighting against, reprogramming, and debugging the entire battery management control.
Why risk it if nobody has yet found a way to win against this Shimano BMS? Boost up the mountain implies higher power draw, so cutting down the capacity will increase wear, possible exceeding the cells discharge rate. Downhill the heavier battery is just a bonus.
Please Battery Doctor can you help me, Do you know the pinout of the charger? 42V+ /rx /tx /empty/ GND? Can you explain which signal is sent from the charger to the battery to connect the outside plug. There must be a Solid state relais or transistor. How can i close this "switch" by CanBus Signal/command?
Hi, why didn't you just put in new temp sensors? They are NTC's 10 kOhm at 25 degrees (C) Or is this BMS 'born to brick'? Is that why you say at 5:40 'if you damage this, it's bye bye'?
Hi. I'm trying to find out if it's possible to charge Shimano steps battery (36 volt) with Genasun GVB-8 Lithium 41.7 Volt WP MPPT? Or is the Shimano system not compatible and designed to not work with any other charging metods? Would hope to do it this way rather than using a powerstation.
For that to work you probably need a DARFON SHIMANO ADAPTER. never tested, meant for discharging but it might work: www.batterytester.nl/Darfon-Shimano-Adapter
I have been looking for a charger for the battery you are working on. BT-E6000. Do you know where I can get one that I don't have to pay over $100 for??
No. $100 is a good price for a advanced charger and its not low enought for any other company to produce a compatible one. Shimano has 2A charger you can get for around €65 i EU.
Can you tell me what brand the lock and cylinder is fitted to a shimano steps BT-E6010 battery please and is it possible to open the battery casing with a T9 tool or something because I have lost my keys and I need to change the lock and cylinder, I purchased my bike from bike fun they have sadly become liquidated. Than In advance great video
So what is the lesson in all of this? Be very wary of buying an ebike with a proprietary battery unless you want to pay through the nose of buying a new battery instead of repairing it. Tjeu aren't manufactured to be repaired 'deliberately' any more than an iphone is.
Hello, I am trying to do the same as you to try to recharge "manually" each section of cells on a BT-E6000. I am no expert but here is what I think, I opened the battery: There are 40 cells and 4 small wires going to the cells. Can I assume the following: 40 cells / 4 = 10 cells per wire = 3.6x10 = 36 v per line @ 2.9A per line / pack x 4 packs = 11.6Ah . The battery is rated 36v 11.6A so I think I may be correct. If I am correct, could I unsolder one side all 4 wires (could do both sides but I dont think it would matter), then use a lab power supply to charge to either 36v or 30v if I cannot find such power supply. After charging a little, I could reconnect the cables and see if my charges could charge.... Any special danger you may think? Alternatively, without unsoldering the wires, could I just apply 36v voltage to big connector on the right of the BMS to go directly to the cells? Thanks, Frederic
@@teddykishi Hello, yes I have managed to do it properly. I recharged each block independantly somehow and then after some charge, I recharged all of them with the charger as intented. I worked. I occasinaly now get an error charging the bike battery but I disconect and reconnect the power and then it is ok.
Still holding a charge ? My Shimano E8035 is not accepting any charge after going flat and I am keen to try your method as it is very unaffordable for me to pay Shimano $1460 AU to replace a two year old battery. Fingers crossed. thankyou for your very important knowhow! Martin@@frederic3913

@@TheBatteryDoctor Are you aware if anyone reverse engineered the BOSCH BMS? In that case, it will be possible to repair any BOSCH battery.
@@TheBatteryDoctor You maybe can reverse engineer the BMS but not the software running on it.
@@zisoskatsiapis656 Yes several, in both china and germany. But they dont sell BMS, they build new compatible batteries.

No because it talks to the motor.

Does Anyone know how to Repair A Shimano BMS which shows A blinking led 1 and 5 after 1 minute of Charging?

Do you still have good BMS From Shimano steps ?

There is no lock in Shimano batteries, its always in the bike, search for a shimano service center and they will help you
Its integral to the battery. Abus mobil 14_003
Yikes, the big companies never make it easy.
Have you ever been able to renew a Shimano battery? e6000 or e8010?
I think that he never did it. If he did and will upload the vid it will be a great battery repair hit.
So what is the lesson in all of this? Be very wary of buying an ebike with a proprietary battery unless you want to pay through the nose of buying a new battery instead of repairing it. Tjeu aren't manufactured to be repaired 'deliberately' any more than an iphone is.
