There is however something you can do to get something similar to your desired behavior. Daarom kan het niet door consumenten veranderd worden. PS: Anyone looking to buy a used BSSHD controller with the throttle mod done. Only in first gear when applying throttle the engine cuts out until applying more throttle, then cuts out again, until max throttle is applied. The 104 BCD adapter is the only way to get a smaller chainring on this motor. I cannot be held responsible for any injuries caused by the use of this firmware, use at your own risk. But most of the displays wont be able to do this. Learn more. 0 is again default, so I dont see a reason to change this. Thanks. I dont really understand the problem you have. Thanks. So to summarize, your firmware needs to reflashed using special programs and procedures. It makes a noise, not more than that. So leave it to default which is undeterminated. A higher current will result in greater torque. But maybe Herve can help you with this, I hope he/she can respond to you. John. Make sure not to hit full throttle in high gears or on a steap incline. I would however not worry at all about having only 5 assist levels. Best regards Franco Rametti Mail franco@ica-net.it. So Ive set 78% for max speed of all PAS and used your suggested % for current limit. Bafang Mid Drives If this is your first visit, be sure to check out the FAQ by clicking the link above. The speed limit is overwritten by the throttle, so you will go as fast as you want. Giel thanks so much and wow that was a fast response. 4. This could be the reason for the error code 30 as well. If your battery voltage was already kind of low, this extra drop in voltage will cause it to go below the low voltage limit. cordially I recommend 80% because this gives plenty of power when a constant speed is reached. Top To maximize range, you should pedal along in the assist level that gives you just enough power so thats is still comfortable. This will mean that your bike will give full power and full speed in PAS 0. Display works correctly, the computer see the controller, I reprogrammed it, but it didnt help. The level correspondence is really convenient to know, thanks for figuring this out. You will often experience that you will have clearance and chainline issues. No, the BBSHD is designed for 48V. I however also dont see how any programming setting could cause this behavior. And can you tell me what the current battery voltage it, when it states 50%? So if this is what the bike reads, it is correct. Bafang released the source code and Stefan Penoff (Penov) took it and made it better. Can I keep the other suggestion values that you recommend in this post to improve my experience of riding, I usually use my bike for mountain terrains. With the Bafang BBSxx motor kits, you can easily change the top speed. First: You accept all responsibility for performing any or all of the steps below, and if your stuff explodes in a supernova, or simply fails to ever work again, sorry about that, I cant help you there. Franco Oui jai reprogramm mon velo de trekking (Fischer ETH1861) avec le logiciel. Programming The BBS02 & BBSHD Without Frying Your Controller And Losing But no connection to Bafang controler. There unfortunately is no way to increase the time that the gear sensor deactivates power. This might give you more control over your bike. My set up is a BBS02 on 750watt. But again, make sure to back-up the factory settings. I have the 500C display and it starts in Level 1 PAS each time, is there a way I can set it to start at level zero? Im happy with all my setting, but which one do I change to tell the motors controller that I have a 52V 17.5Ah/910Wh battery? So if either of the above gives you even the slightest hesitation, stop reading and go ride. A COM port (often Com5) will be assigned to the portif it tells you which one that is, write it down. 13- You should see the progress bar scroll across if it is successful. I checked all connections. Ich kann Ihnen leider nicht mit Ihrem M500 Motor helfen. The lower this setting, the faster the drive unit will decrease power as you pedal faster. Your COM port is not working correctly, try another port and see if it comes up in software. Manufacturer: SZBF You should set this at 44 instead of 41. I wont have a video available in a while, this will be something that might come available in the long run. Leave this setting to 11, changing it can give problems to the response of your throttle. Now I can no longer connect to the controller with pc and when I connect controller back to the screen I get an error code 30. stc-isp-15xx-v6.86E.zip If I hadnt gone through the trouble of making gaskets and siliconing in the new controller Id be tempted to give this a whirl. When you disconnected, the firmware might have only been uploaded partially. I would say 20% is around at 3.5V (45.5V for 48V battery). Windows 10 USB Driver: Bafang BBS02B 750w 48v That assistance will draw a certain amount of current, which will determine your range. Quick question. NOTE: Presumably this means you follow these steps: I would warn anyone when pulling them connectors apart to be extra careful and avoid pulling on cable as I probably broke them wires when separating to hook up the usb cable. I dont know if this will also disable the throttle though, you would have to test. Controller CR X10B.250.SN.U 3.0 Latest version uploaded on 16.05.2017 with a few updates. Following the Bafang configuration tool instruction I installed the parameters you recommended. it was a defective USB cable. It cannot be done with the programming software in this post. If you want the pedal-assist to start the fastest when you just pedal a small bit, change it to 2. No particular worries. It should be completely automatic regarding this. Would this scenario cause damage? Therefore the display will think that the battery is less full when you are driving. To obtain more torque with lower speed, I set these values in the BASIC card. I lost the original configuration and if someone could give it to me. Interesting now even the battery percent is pretty accurate even though I normally have the display set to volts. Hello, I have the Bafang BBS02 750 Watt 48V. If not, still try a different monitor resolution, this might fix the window issue you have. The range is dependent on so called watthours (Wh). Your rear cassette, should have a 11T sprocket. My guess is that the BBS3 version controller of the BBSHD is now 28A. So I am curious if you were able to do that. Can you help with that? Assist 2 40 / 100 This motor was only rated at 250 w. The throttle isnt a big deal to me. The heavy load on the motor indeed could have caused some problems with the controller. If you set this setting higher, it will assist more when you have reached a constant speed. Just want to say that I REALLY appreciate what youre doing, taking time out of your day to explain help people out. If you want the throttle to give more power and react more aggressive from the start you should adjust the following setting: You can increase the start current in the throttle tab. If you do this however, the pedal assist will also work. This is the correct value for a 48V battery. If you have a 36V battery, it should be set to 31-32V. You should first fix this error. This setting determines the amount of time the system takes to reduce the power when you stop pedaling. Check if these settings are set to my recommended values. https://github.com/danielnilsson9/bbshd-fw/wiki/Configuration-Tool. Let me ask you one more question. Order Numbers should be 6 or less numbers (Examples: 1234 or 123456) Message *. Questions: You can feel this when pedalling as well, if you go to slow, you cant apply any pedal power. Karl. HI Giel, First of all, thank you so much for your post, its very useful. 3. 9a- Turn off ebike batterys power switch As for the DPC18 display with 5 assistance levels, I have seen that the coupling of the 5 levels with the 9 levels of the controller are: Assist 1 of the display corresponds to assist 2 of the controller Assist 2 of the display corresponds to Assist 4 of the controller. After 8 months of various tests I give you my configuration for my electric bike Fischer ETH1861, Bafang M400 motor, Battery 557 Wh 48V / 11.6 A If you want a wider range of control with your throttle you can set this to a maximum of 42. Its a shame that the Bafang controllers tend to be quite unreliable and sensitive. My cable should be here in a few days, cant wait to get started on reprogramming! Good luck! cordially, Bonjour, At first it worked strange, power jumped from 0 to max at any level, but now it works correctly. Is is really weird that changing the setting on the display doesnt change the read out. Close to ordering the programming cable and start having fun with my bike as well. So when searching for a battery you should look at the Wh specification. A user called Herve, has confirmed that he has reprogrammed his M400 though. You can also decrease the start current. This setting will prevent damage to your battery. If you want maximize the torque you will automatically accelerate faster than at lower power values. Apart from that, I dont see any obvious reasons why it wouldnt work. Hi, I understand that this might be confusing. For the BBS01 the maximum value is 15A. I should have broke apart with a flat screwdriver first!! But again, I find that limiting the maximum speed by limiting the current makes more sense. But if you are able to sensibly shift without the gear sensor, you should be fine as well. This differs from seller to seller though, so there isnt really a stock current setting in the firmware. So would definitely give that a try. If you have a 52V battery, you need to set this value to 44. I know that will work with 30 amps. This is the case because the display will think that you use a 48v battery. That would be really unfortunate for you, but it could be possible. You should set this to 44 instead of 41 for the 48V battery. Anything other than 60 or 80 is not recommended. Does it not turn on anymore? Did the controller fail right after the usb procedure? But your behaviour is a bit weird. Reading on internet looks the read out % depend on de battery voltage and the voltage of the motor controller. Or is there anything I can do in the programme so I can keep up with my bike? For a fat bike the wheel diameter is close to 29 inches, this is whats suggested, set it to kmph and change the wheel size to 18. Hello, would you please advice on how to fix an issue, I do not see the Connect tab active. Only difference is battery protect at 30 and have amps at 20(where I have had it for the last 1000 ks) I dont know if your decrease in power is caused by the fact that your battery is less full. This also is the only way to change the read out. You dont have to do anything else. Thank you for your advise. So thats the only way to do it. My question is this. Can it be changed with the programming cable. Do you use gear sensor? SOLVED! Hi Giel, i have a BBSHD hot rod program with a 52v battery. Although this one is hard to change on an existing bike, bigger wheels also improve cadence. I do not see the profiles or the pdf file. I was wondering if you know what is the *stock* current limit for this model? thx giel, problem solved. Off topic comments are not a problem at all! Best regards. Thanks Giel, I agree as do many that the Bafang I think that the motor turns at maximum speed, but because of the gearing and small wheels, 24 will be the top speed at those gear ratios. I used the same manual settings from this site. The controller is CR R209.750.SN.U 1.1. Even if you would make a bad shift in a really high power mode, you wont brake anything. Are you talking about maintenance of the Bafang motor? What I meant with controller programming part is broken is that the physical circuit board responsible for programming is broken inside the controller. I intended to use this on a touring bike. This would increase both your top speed while pedalling or when using the throttle. I believe Bafang has disabled this option in later/current controllers. If you want insane power, get the BBSHD, this motor has a 30A controller. This is the case with your controller. I normally try to do this but is not always possible I really appreciate your advice . But I am glad it works. Read and Wrtie tabs are eather inactive. This firmware is intended to replace the original Bafang firmware on the BBSHD/BBS02 motor controller. This behaviour can be normal, because when you accelerate, the battery voltage drops. 1 Download the file stc-isp6.86.rar from http://www.stcmicro.com/rjxz.html If you in addition to that also have low gearing, you wont be able to reach higher speeds. This will decide how many levels of throttle power you will have. This is a safety feature designed to keep the battery in good health. Regards, So it is not possible to have PAS 0 as a throttle only setting. The tool helps in disagnosis and detecting errors. I rewrote them to compensate for filename changes of whats actually on the first site, and the filename of the actual firmware file sent, and combined the two separate sets of instructions given as they cover the same things in different levels of detail. 2 Extract stc-isp-15xx-v6.86E.exe from that file (using WinRar, 7zip, etc; a google search will locate the appropriate websites for those, and instructions how to use them) and run the program In order to change the speed limit with the help of the display you have to set this to By Displays Command. Its not a familiar problem for me. Since with that much power you can easily strip gears when you dont select the right gear. You may have one of the following problems: You dont have the necessary usb drivers installed.

Im trying to use your instructions to reprogram my Dost Kope Bike. But dont know what type of motor. 2) The way you describe this is wrong, the controller doesnt work like that. First of all, you state that you dont really care that much about range and that you want a small battery. I would like to ride without power on level ground but there is too much drag. So by setting the 9 assistance levels on the Settings in the first tab (Basic) I found that the Ebike responds perfectly on paved roads and on wide dirt roads, but when the paths become narrow and demanding if I enter level 4-5 to have more power the speed is too high to lead the Ebike safely. You should do this in addition to the manual driver. You should match it with your bike, otherwise the speed measurement will be incorrect. Such as start current and slow start. all my normal mountain bikes run a 28 or 30 tooth front chain ring with 42 or 46 or 51 tooth cog at the back on the cassette.

By tweaking these settings, you can make the throttle respond more to your liking. the issue is now fixed and I have been able to reset all the values and save on my PC. A 17Ah or 13Ah will definitely not give the same range, at the same speeds. You probably wont be able to change the top speed at all. 18- ride and have fun! If it has a torque sensor, the settings will be different. Ich hoffe, Sie finden etwas heraus, das fr Sie funktioniert. Hi Dima, I am having the same problem. The software cant adjust gear ratios unfortunately. A tag already exists with the provided branch name. BBSHD firmware | Electric Bike Forums - Q&A, Help, Reviews and Maintenance So dont change it to something different. So this is not something I would recommend at all. But Id like a 5 PAS setting from 15 to 60 km/h. 26 (to reflect the size of the drive wheel) so that i do not do damage to the motor? So dont be to worried about it, if you always pedal along and use the throttle in short bursts (like you state) you will be absolutely fine. It could just be normal behaviour (due to less full battery), but thats hard to tell from here. controller programming part is broken kindly elaborate, not sure if its a physical or software part, is it external to the bafang controller or inside the controller. How can I make it appear? thanks for you time and passion in sharing your experiences.My sole purpose to get a mid drive kit is so I can tow my 2 kids ( 7 year old and 5 year old) up the hills when we go mountain biking. Use Git or checkout with SVN using the web URL. This process can be used to fix the error 30 code, unlock your controllers, and switch . I know you stated that under the throttle handle you should keep start current [%] to 10, i would like to know if 15 is too much for my set up and also if switching to speed mode instead of current is safe for the BBSHD. If you follow the steps of this video, are you then able to set it to 9? would you get the same or less mileage assuming you used the same amount of cells in battery packs so you have 52v 20ah vs 36v 31ah which cost the same which would go further? Herve, Hello, I suspect this only happens in the highest gear? If you find that all other things will not fix the issue, you could try this as a last resort. The current limit is still is 0%, therefore the bike wont get any power anyway. I used your settings and everything went well. I have programmed to your suggested settings.

This therefore increases the amount of friction, which results in the feeling of more drag. It, in turn, will decide how fast the e-bike will accelerate. If this doesnt work, there is no option to deactivate the PAS in software. And what display are you using? The DPC-18 display is the fanciest most sleek Bafang display. You just pedal along in the assist level that you find that gives enough assistance. If you have another Bafang version you cannot use these files. zie wel de voltage maar niet het bereik de RANGE is dit een fout of hoort dit zo How long had you had this controller? (Higher start current). If it says 40%, the battery often is more like 20% charged. Alright! You can only change the low voltage cut-off. It isnt worth it to pedal with an unnaturally high cadence to improve the efficiency of the motor just the slightest bit. I can understand that its massively frustrating, I sympathize with you. The weather is supposed to be so so over the weekend too so hopefully ill be able to tune it, then try it and adjust as required. I am unable to get a connection with the controller.

Hi Giel, Thanks for taking the time to reply to my issues with programming my BSSHD controller. Any advice you have on maximizing battery run time would be greatly appreciated. I would contact your seller about this, if this is the case. For a better experience, please enable JavaScript in your browser before proceeding. Refinements being (my favorites, anyway): Unfortunately, I dont have the knowledge nor experience with serial communication methods to help you. Would it work if the speed limit on the second tab(Pedal assist) was 40km/h?? What would you say to resetting the parameter for the wheel diameter in order to achieve a sort of cheap and simple speed hack? This is how the controller calculates speed. If you dont KNOW that you need this fix, DONT do it. My friend has the same bafang motor and his monitor shows percentage right (100%). Because if you ride uphill a lot, you will probably like to have a little more kick in the start. This is a big deal to me because of all the very steep but short hills where I ride. Can you help me with any suggestions? Do you think this is sufficient for my needs as listed above? Runs 40km/h on flat ground. I do not have PAS setting in the display. You can always set the speed limit on the display to 25 km/h. Or is it to new, so it doesnt exist at the Moment and it can take something? The performance and features are pretty much equal for all displays, so the make your decision based on looks. The problem with this is that you cant pedal along in low gears since the cadence of your own pedaling would need to be really high. After 3 years you could maybe open it open put new grease in it. Would it work if I changed the speed limit of the secend tab(Pedal Assist) to 40 Km/h ?? I have the cable provided by Bafang that I connect to the display cable as described, I installed the x64 win10 version of the proposed driver. 1 Tommycat commented 03-14-2021, 05:26 AM Hi Giel, I have just purchased a BBS02 48v 750w (with 25 amp upgraded IRFB3077 mosfets controller) with 850C display and 48v LG battery. It will also require lots of modding and advanced knowledge. You ofcourse can always try a different pc, to see if this makes any difference. If nothing happens, download GitHub Desktop and try again. The config windows are too small and I cant access all the settings. You are also addressing the fact that you cant keep up with the motor at high power levels due to the high rpm. And if they are not willing to ship one out for free, they might be able to reduce the price of the replacement. It can be bad if you wont pedal at all and let the motor do all the work with the throttle for example. I should just hold on to your spare controller, it is always nice to have one spare. I am able to edit all of my settings, the bike is read once I open the config software. What are the implications if I set the Current Limit in Assist 1 to 20 and increase all other levels by 10 percent? Hello. Just make sure that you program the 5 assist levels in such a way that they give good control. You just confirmed that this version doesnt have a throttle connection. EDIT: heres a pic of a bafang usb-serial cable: Can this motor be used with a different controller to give me use of a throttle? It will even increase the lifetime of the motor by using it at lower power levels. Now, with the new controller, my bike is slow and the assistance is not the same as before. I recommend current since this is easier to calculate by your controller. Current A was 20A Those inaccurate measurements unfortunately cant be fixed. Click File in the left top corner of the program. The 500c display only has up to 5 PAS levels. 4. It also is not too responsive, which is good. Id like one level to only respond to the throttle, no pedal assist. bbshd instructions rewrite.txt This way you can easily change it to your likings. I should set it at: by displays command. In general, a full 18650 has a voltage of 4.2V @100% and a voltage of 3.2V @0%. To my knowledge the modes dont matter when you reprogram it. What do you mean with flashing new 48v firmware? So the max current should be 13A. So for the BBS01, BBS02 and BBSHD. Frank. No problem! Indeed, I do not know if the M400 is in BB-32 or Double signal 24. You should do it manually by braking just a little so that the cut off will activate. My question is this: I have just bought a bafang 500w mid drive motor with an 850c controller. Maybe I need to adjust something in the programing? This way the throttle will always have a 100% current and speed limit, no matter the PAS level selected. And even it goes it can stops at any moment. Hi Giel, that is correct. Lets say at PAS 1 and 4th gear the torque available at set current% is not enough to turn the motor without additional human power. The battery is completely empty at around 41V. You then multiply the voltages with 13 to get the voltages for a 48V battery.
