What you need to check though is if the cut-off voltage in the programming software is set to the correct value. and I made use of gogle translator. There may be a lot of that back and forth till i get it right. Do you have the BBSHD? First Name Last Name. Video & Photo File Upload. I know with the display when you change the speed assist level from 0 to for instance 5, it directly changes. If you decrease slow start, you will accelerate faster. I am talking about these extreme situation. (3.71 KiB) Downloaded 770 times But if you do this, you will only have 250W power ofcourse. Special programs and procedures are needed to execute this firmware update. Here is what I did.

Normally the gear-sensor takes the load off, but when it comes back it sometimes happens. In order to start reprogramming your Bafang BBSxx mid-drive system, you will need a programming cable. As of the display, it doesnt really matter which you choose. If this is not stated, you can easily calculate it yourself as demonstrated. You can always set the speed limit on the display to 25 km/h. I will try to answer them within 24 hours. Thanks a lot for this awesome guide. It kinda stalls at first press and takes a few seconds to get the bike going even at a slow 10km/hr. How to Fix Bafang BBSHD & BBS02 Error 30: 1. I have tried to let the LCD control the speed, which I maxed out, and that isnt getting me any more speed. Nominale voltage: 48 52 First of all, you state that you dont really care that much about range and that you want a small battery. Again, good luck, I hope you are able to fix it! With 12-14Ah, you could have some range anxiety ;p. The BBS02 750W will have more than enough power for you needs, the BBSHD definitely isnt necessary. But most of the time this is the case, even though it is not always clearly stated. I will try a new cable, if that doesnt work maybe I will need to replace the controller?

I do not see the profiles or the pdf file. If you want to avoid it completely, you will have to opt for hub motor style e-bikes. For example 44T in front 13T in the rear. I have a Victesse bike with a bafang M400 and a 36V/10.4Ah and 374 Wats. I would just keep the current limit of PAS 0 on 0 however. Another thing to consider is that most of the time, the display will display a wrong battery percentage. I do know that permanent magnet brushless motors like the Bafang motor most of the time will operate more efficiently at higher RPM. Maybe some mosfets are blown inside. Will see how it goes tomorrow. I see that the Bafang kit comes with a monster 44 tooth or larger ring. It is effectively the thing you would do when using the throttle, the motor will do all the work. Andy. The kids are really getting into trail riding and an ebike will help me ( and the kids) with our own personal energy levels. Sorry I misunderstood your question. You can just assume that if you read your controller settings, that those settings are close to usual stock settings. The Bafang kits indeed comes with 44T or bigger chainrings. M625/M325 USER MANUAL [FR] Installation and usage instructions . Or is there anything I can do in the programme so I can keep up with my bike? This tells me the problem is with the controller instead of the battery and display error.

You can also decrease the start current. I have an M400 250W Motor, 557 Wh 48V battery. For example if you select a small cog ( ex: 15T with a 42T ring) if the current limit of the selected PAS is too low, could it put to much stress on the motor as it will try to ramp the speed to high? 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. Im using a laptop with windows 7. Settings in your description above, and it is started to happen some days ago. 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.

Exept for the designated assist level. Programming software - Available by signing up/logging in and then clicking on the Download button above. But dont know what type of motor. Or does the display still work? https://endless-sphere.com/forums/viewtopic.php?t=93000 The better way of doing it is just to change the power level for the different assist levels. Thanks, Giel! Especially with the 52T. Unfortunately the Bafang throttle can feel a bit jerky. There is however something you can do to get something similar to your desired behavior. (19.86 KiB) Downloaded 869 times. It indeed is a mistake of the previous owner if he set it at 26 in settings, but attached it to the 20 wheel, this will not work correctly. I dont have any experience with programming the Bafang m400 motor. So why your controller failed is not clear to me. https://github.com/danielnilsson9/bbshd-fw/wiki/Flashing-the-Firmware, Configure Bye., Franco So you can maintain that speed. If you set this setting higher, it will assist more when you have reached a constant speed. What you say about the definition of speed %limit is true. You cant actually change the allowance for 52V using this programming software. Almost all functionality of original firmware has been implemented and additional features have been added. De eco en sport modes zijn niet te configureren. I havent ever tuned an Ultra myself, but the procedure should be the same. I also have never had my hands on such a motor, so I unfortunately cannot tell you anything about programming that specific motor. Thank you. This is true in the sense that the speed limit you set will in most cases be hit first. If the programming cable doesnt fit your connector I would not attempt to change the pin-out. In your reply to me you stated that their is another controller for the M400 that will accept throttle. Can you direct me to this controller, I do have a tech that says he can program the controller for me. This is a difficult error to fix since it can be caused by a lot of things. This can be simply done in the display menu. If you want less power, you should decrease this number. Following the Bafang configuration tool instruction I installed the parameters you recommended. The throttle settings are set as per this article. Hi Frank, have you adjusted the settings and if so how did you go? By setting all the other assistance levels (0-1-3-5-7) to 0 (zero) the controller works perfectly and selecting the 5 assistance levels from the display changes the motor rotation speed. So keep in mind that displayed percentage probably is higher than the actual battery percentage. If all those fixes dont work, it could be that the controller is simply broken. I really want to make these improvements to my bike! Only increase the settings in small steps and do intermediate test. The wheels are 20in.

So if either of the above gives you even the slightest hesitation, stop reading and go ride. Please help! 0 is again default, so I dont see a reason to change this. Hello! Hello, Is any chance to program BBS02 500Watt 36V to turn off pedal assist and use only throttle ? If the voltage of your battery is 52.6V, it isnt 100% charged. I recommend 36, since this is the default and in my opinion, works perfectly. So the new controllers are simply slightly less powerful. This way you can easily change it to your likings. The situation that you are describing wont cause damage to the moter. Thanks, I did try the 100% speed limit. I run a XT derailleur with a Sram cassette. What current limit (A) i can put on the first page, I mean, what is the maximum number? Now show the display full range 100%. I just bought it one week ago and battery show me wrong percentage on the screen. Thank You! Hi, I need to really go through it but it seems they have these well set up out the box. This could be the reason for the error code 30 as well. Its a shame that the Bafang controllers tend to be quite unreliable and sensitive. Its good that I didnt touch anything than. I am a little confused about why your controller isnt 30A. It cannot be done with the programming software in this post. Thanks Giel . The level 0 is meant so that you can have the bike on, but without pedal assist or throttle. But probably the only thing that you should change, is the current limit. Can this motor be used with a different controller to give me use of a throttle? Are the LEDs still lighting up on the usb programming cable? If you are happy with the way it rides, just keep those settings, other settings will not improve your range. My question is: I have a motor of 48 V and my battery is 52V have any consequences if I will used it together? In my opinion, you are better of with 5 even if you can choose 9 as well. The motor therefore will not engage. Or is it to new, so it doesnt exist at the Moment and it can take something? There is a sticker on my motor that reads 48V. Hii!! I am a strong cyclist and I find the assist levels to be too strong for the most part. The tuning method is only possible on Bafang BBSxx series motors. Daarom kan het niet door consumenten veranderd worden. If you want the e-bike to be limited to a certain speed that cant be changed on the display, you have to assign a certain speed to this setting. Whats the point? The controller you have can handle a maximum current of 25A. You also risk burning out your controller if set too high. I like pedal a lot and use assist by motor using only by throttle? Bafang 8Fun Programming Software & Guide (BBS02, BBSHD) No ebike is perfect, this is a thread dedicated to sharing known issues or problems with electric motors from Bafang as well as any help and solutions you know of. I did some calculation and the speed I got was in fact 30% of max motor rpm, ~40rpm for that cog. There was a problem preparing your codespace, please try again. I dont know if this will also disable the throttle though, you would have to test. I would suggest reading about the error online and trying all the mentioned possible fixes. Its not a big problem that you already bought a replacement controller. This is just the limit of the bikes gearing, they were in the first place never designed to run at speeds above 50 km/h. But I am pretty sure it uses those levels. If you change the wrong settings and you dont exactly know what you are doing, damage can be done to the controller. My engine is 350W and 36A of batterie (everything is the same as before). A fully charged 48V battery would he 54.6V. It indeed can help other people, so thanks for that.

Setting the speed limit to 100% doesnt mean that the motor will try to ramp up the speed indefinitely. I meant if we should do some service work with the motor after maintenance, during exploitation, open it, check smth, grease. This can be convenient if you show the bike to someone new for example. The lower this setting, the faster the drive unit will decrease power as you pedal faster. The display you have indeed has two modes: standard and sport. If you want to pedal more yourself and save more battery at a constant speed, set it to 60%. Display works correctly, the computer see the controller, I reprogrammed it, but it didnt help. My cable should be here in a few days, cant wait to get started on reprogramming! Good luck! Your own power can than all be used to propel the bike. In addition to spinning the wheel, you will also be spinning the motor. I just want to unlock the speed limit of the 36V 350W model. But getting the exact same settings on there as the old controller is definitely something that you should try first. Bafang BBS02 500 Watt 36V:https://drive.google.com/file/d/1pezpHsR6sLzx_kXPQ1v9luHHsueX6jyB/view?usp=sharingBafang BBS02 750 Watt 48V:https://drive.google.com/open?id=1sxLa99ycpnrktxezmi-BswAjgvsrm_LCBafang BBSHD 1000 Watt 48V:https://drive.google.com/open?id=1zS03gj-v-EZNjiRqACd0LOi5ydOOsyIN. This way, the bike will stop assisting when a certain speed is reached, therefore it will not reach speeds out of your control. This setting will decide how much current the motor will draw on startup. The chainline can then indeed be a problem, but this differs from every bike. I would like to know what settings are needed to protect the controller and provide optimal performance when using a 52V battery. Changing it to 0 or 1 wont work, so dont do that. I unfortunately cannot help you with your M500 motor. The Bafang configuration tool link says the file is in your trash. Assist Level/Current Limit [%]/ Im still experimenting. My question is this: I have just bought a bafang 500w mid drive motor with an 850c controller. Can you tell me what controller is on your bike? 09-01-2019, 08:38 AM. Left it @ 20A. So overall your plan to set the current limits low, just cycle along as a strong cyclists, to maximize range, is a perfectly fine strategy! Therefore the display will think that the battery is less full when you are driving. motor: BBS02 mid-drive 48V 750W If the answer is yes and the thinking is that it will make me go faster, will that only be true for pedaling or will it also be true for using throttle only? So you can absolutely only change the current limit and have the same recommended settings for the BBSHD. Like expected, it has something to do with the controller versions. The setting can be found using the following steps: This video clearly explains how to access those settings on your display. display controller: 860C, The 860C has a setting for me to change the voltage to 52V (nice). Ex, when I have full battery, screen show 55 60%. That really nice! Sometimes that means a DIY fix and other times it can mean a recall, software update or part replacement by a dealer. You should do this in addition to the manual driver. Your way to obtain maximum torque at lower speed is indeed what I would do as well, great description. The current limit is still is 0%, therefore the bike wont get any power anyway. These are actually one of the biggest batteries that you can buy for diy purposes. I used the same manual settings from this site. 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. Windows Laptop / PC - Required to install and run the programming software. I probably Will order an other Bafang controller if I have to for now.

Bafang BBS02B 750w 48v This will decide how many levels of throttle power you will have. Off topic comments are not a problem at all! Have you ever check if these settings are also applicable to the Bafang Max Drive M400? So I would just say to pedal in the gear in which you can put in your own leg power the most comfortably. (3.5 MiB) Downloaded 602 times Best regards. Thanks Zeeshan, ill give that a go and see how i get on. Did anyone had the same issue or any advice? So you cant really increase range by changing some settings. If not: do you know a way to change the settings of the M420? Its not a familiar problem for me. This way the throttle will give maximum power in all assist levels. i know this is a bit of a different question, but do you think it is possible to set the controller to 25km/h on startup every time when it is started? The ebike will then just get up to the maximum speed that can be reached with that amount of power. I have a 36v 500w bafang mm g340.500 07 motor. Let me know. AS AN AMAZON ASSOCIATE I EARN FROM QUALIFYING PURCHASES. Runs 40km/h on flat ground. The battery percentage indicator tends to be a bit inaccurate on the Bafang displays. Anyway, I feel like a complete fool. But your behaviour is a bit weird. It will inevitably be some trial and error process. Will thry original software today. It doesnt really allow for a gradual increase in power. Which settings should I assign to the 9 assistance levels so that they become 5, to always have the maximum engine torque, but with reduced speed? Hardware version: V1.5 Ive also included the original instructions at the end of the text file attached to this post (which also contains these instructions). In diesem Video zeigen wir euch, wie ein Firmware-Update am Bafang BBSHD Mittelmotor vorgenommen wird. In that case the freewheel system will be active. Your COM port is not working correctly, try another port and see if it comes up in software. The setup explained isnt for the Bafang M620. The battery voltage to battery capacity differs a lot between different 18650 cells. Enjoy your e-bike anyway! All the settings are the same but the software that Penoff has written fixes . de andere motoren doen die dat wel zoals de BBSHD. Strange. You should carefully select gears though when accelerating. Hi, Problem Im able to connect the USB cable, it shows on the configuration programs as COM3, I hit connect it shows connected, but the Read button is remaining gray and no info is coming from the controller. You indeed will need the datasheet of your specific cell type. If you dont want to know about all the settings, but just want a better configuration, you can use my configuration. The error code 30 is probably also the cause of why the programming doesnt work. The setting on the display will set this setting and the pedal-assist setting at the same time. If your display doesnt support a 52V battery mode, your battery percentage indicator will be useless as well. Thats unfortunately just how most factory ebikes will be. My dealer stated that he didnt know the Luna motor wouldnt automatically adjust for my 52v battery, so he will need to reprogram it. Is my range normal ? I bought a bbshd about 7 months ago which i have on another bike . Just try to apply the power gently in the higher gears to prevent excessive wear caused by those slips.

Top But if you are able to sensibly shift without the gear sensor, you should be fine as well. The only thing you should change is the low battery protection. Do you think that because I did not Connect in the correct order that I may have somehow damaged the circuit board or was it just bad luck. And can you tell me what the current battery voltage it, when it states 50%? I have recently installed the Bafang kit on my Cannondale Full MTB. The BBS02 750W will deliver more than enough power. mijn vrouw heeft een amslod met de M400 die ziet hey wel. Like Like. This setting determines the amount of time the system takes to reduce the power when you stop pedaling. Controller CR X10B.250.SN.U 3.0 Another method Ive heard of for the same settings is 1%, 1% & 9 . I understand your question. He uses software that has the torque sensing page also. I wont have a video available in a while, this will be something that might come available in the long run. Is there any other way to turn the battery back on? Ive been a Mac guy for years so I had to dig up some old hardware. But again, I find that limiting the maximum speed by limiting the current makes more sense. My question is, do you have to pedal along with high RPMs that the Bafang motors like in order to keep motor safe at low current% and 100%speed? top dank u wel voor de reactie . . . I would be retrofitting this to a legit mountain bike one of my bikes is a hard tail with a legit front fork, legit hydraulic disc brakes and 1 x 10 shimano drivetrain.

I do not recommend settings this higher than 10, otherwise, you can wheelie of the bike because of the insane power. But this way you can have PAS 1 as the no power setting on startup as a safety feature. Je recherche des sites ou des personnes ayant reprogramm ce moteur ou vlo. In that case the only option to go faster would indeed be to increase the chainring size in front, or to decrease the lowest gear size in the rear (or both). Error code 30 indicates an communication error. Its unlikely that it can damage your motor, but it definitely will give an incorrect speed. When I switch off my bike (fully) and on after about 3 minutes, there are 5 indicators How does this happen? 3) power on battery On bike I have had a strange performing controller that I couldnt reprogramm either. The BBS02B is the newest improved version. This way the motor can overcome its own friction. So if you really want a smaller size, I would recommend 12-14Ah. Regards, John. Does the throttle do anything in your assist level 0? 4 Open the STC programing software. To summarize: You cant adjust torque, without adjusting power and therefore speed.
