A programming fix is finally available to address this oversight. You then should look up how you can change the speed limit on your display. Even with the inability to write and the weird load results? Therefore it could be possible that you destroyed your IGH with the power of the BBSHD. Its unlikely that it can damage your motor, but it definitely will give an incorrect speed. If the display doesnt work, you can try to engage the bike in this way: https://youtu.be/rdsmplS1N10. This setting will decide how much current the motor will immediately draw when the throttle is engaged. Tongsheng TSDZ2 vs Bafang BBS02 Which one is for you? Thank you for this great guide, it really did help. You can change some settings a bit, to make it better though. Thanks for your detailed explanation on your problems. Hope this helped you, if you have any further questions, let me know. Hello Charlie, On my side the bike only works on the road because it is a Trekking. It could also be that another setting in combination with the current limit is conflicting. I recommend 10% because this is a safe setting. Try to see if your belt has enough tension in the first place. Awesome website and lots of great information explained in plain english!

You will have to replace the controller and then it will work again. The Bafang programming feature is ONLY for the Bafang mid-drive motors. There for sure isnt a different version of the DPC18 display. I have no experience with the M400, so I unfortunately cannot help you with this. If you have any questions, please leave them in this comment section. I have had bad controllers, but I have never had one fail during or before a reprogramming procedure. Herve, Hello, Top Thats a weird problem, thats not known to me. That means motor is consistently wanting to help until it reaches steady 90RPM witch is 20mph but it never reaches 20mph because biker is happy cruising at 60RPM.

(1.23 KiB) Downloaded 470 times A list of ebike & bicycle acronyms & definitions to help out new members! I would like to do 90 to 20 %. You can only stop this acceleration by setting speed limits. So I would just say to pedal in the gear in which you can put in your own leg power the most comfortably. So this is no problem at all. Yes, to my knowledge you cant actually utilize the sport and normal modus with the programming software in combination with a BBSxx system. bafang programming cable.jpeg It seems the max speed is the only thing they have been a bit restrictive with(40kmph). I have reprogrammed my controller which was 52v to 48v. Since with that much power you can easily strip gears when you dont select the right gear. CRR10E4830E105001.1_190413-1.txt Im still waiting for my programming cable to come in, But what Im hoping to achieve is to maximize my battery life and therefore range. Anyone have any more news? Hii!! So lets say you climb a hill, in the highest gear, without pedalling with 5% current limit. Enjoy your e-bike! I personally (and know a lot of other riders) also use only 5 levels. I tried adjusting the resolution, but that didnt help. Green Red ???? According to Luna the controllers currently being shipped from Bafang no longer have the issue with the non-progressive throttle while peddling. Can you tell me please if I can make tuning? Make sure not to hit full throttle in high gears or on a steap incline. Thanks. However, my bike has a rear wheel hub motor. It can be bad if you wont pedal at all and let the motor do all the work with the throttle for example. You can just assume that if you read your controller settings, that those settings are close to usual stock settings. I got this idea of a retro fit after riding my friends full on Norco Range VLT E-MTB with the Shimano Steps motor. I also dont think that you can improve your range with reprogramming certain settings. You will also have to change the Designated Assist Level to 9. I recommend 4 because this results in a responsive system. The throttle isnt working when the pedal assist is set to zero . So always move away from a standstill in the same gear as you would do normally without an electric motor assisting you. Thank you!

I have a rear-drive motor (this one: https://bafang-e.com/oem-area/components/component/motor/rm-g060750dc/). This firmware is intended to replace the original Bafang firmware on the BBSHD/BBS02 motor controller. Another thing Id like to ask you about is wheel size. You are good to go! Hi there was the best setup for bbs02b version 1,Its the newest version, 2. So if you want these settings, follow the steps above. Is this the factory setting? Hey! The BBSHD can handle max 30A, the BBS02 can handle max 25A. It would have been amazing if you could reprogram the hub motors as well. The heavy load on the motor indeed could have caused some problems with the controller.

If the controller works fine for the bike part, I wouldnt replace it though. Great that you liked the post, thanks! 13- You should see the progress bar scroll across if it is successful. Close the program, unplug the battery, unplug the programming cable, plug in the display cable and connect the battery again. If you search on m400 on this page (CRTL + F), you will be able to find his comments. This is the case because the motor is loaded while you are riding on it. My problem with the BBSHD controller ! Lets see: If the firmware is really damaged, you could be in trouble. stc-isp6.86.rar If you want higher acceleration you can set this value to 20 or 30. UPDATE: A hacker from Norway named Penoff used the source code and completely rewrote the Bafang programming software. If you dont want to know about all the settings, but just want a better configuration, you can use my configuration. Hi Giel, that is correct. If you found this advice helpful, supporting contributions are accepted here. Best regards Franco Rametti Mail franco@ica-net.it. Only change the setting Wheel Diameter[inch] to your wheel diameter, leave the other settings unchanged. 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. The first question I already answered in another comment of you. I have BBSHD motor and 48V battery. I guess the reason is that I was catched by heavy rain some days before. 1 comment #2.

The second bike shows a 52.6 volt battery but +/- 66%. So this is not something I would recommend at all. Not often but 2 or 3 times at a 20km run. Hi, This therefore can be unsafe. Check all the connections and make sure they are connected properly. This therefore increases the amount of friction, which results in the feeling of more drag. This setting works as a sort of cruise control, If you pedal and use the throttle at the same time, the motor will cut off above 40km/u. This is the case on all BBSxx motors and unfortunately cant be changed. If you want less power, turn down the current limit. This is a sneaky but important setting. . You will probably figure this out yourself by just uploading, testing and changing some settings. Assist 2 40 / 100 Usually when it recognizes the port, it should be able to connect. In your response to Bens question, you said as long as you pedal along with motor having current% set low will not hurt motor. My battery range is 100Km, normaly i use 1/5 2/5 PASS . The 500c display only has up to 5 PAS levels. Bafang BBS02 Review Is it really that good? I just bought it one week ago and battery show me wrong percentage on the screen. I recommend 4, because this is a nice sweet spot. The level 0 is meant so that you can have the bike on, but without pedal assist or throttle. These instructions on updating the Bafang BBSHD firmware, to fix the problem with using 52v packs, were sent to me anonymously. I however also dont see how any programming setting could cause this behavior. Can I set the pedal assist zero setting of current limit and speed limit to 100%? Der Mario. I hope this answers your question :). I will look into this. Thx, Erwin. This is not what happens in practice though. I hope that this explanation is clear to you. I have figured for my needs it is Likely the 750W BBS02 with a 48 V battery 17ah with a 500c controller. Most of the time, if something is wrong, the load function will not work either.

When I change the batteries between the 2 bikes, now the first battery shows the wrong percentage on the second bike and the second battery is OK on the first bike! Maybe somebody know the answer to my problem. So you can maintain that speed. Having max throttle power in all PAS levels is definitely something that you can do with the programming software. This setting will decide how fast the motor will stop assisting when you stop pedaling. If you have purchased the cable, installed the driver, and installed the configuration tool you are ready to go. So if you set this setting really low, then the motor will assist less when you have reached a constant speed.

You should set this to 44 instead of 41 for the 48V battery. I would like to know which motor you have exactly and which display. A 17Ah will likely give you 75km range at those speeds. You are also addressing the fact that you cant keep up with the motor at high power levels due to the high rpm. If this is not stated, you can easily calculate it yourself as demonstrated. Now follow the following steps in order: You are now ready to start using the configuration tool. The battery percentage indicator tends to be a bit inaccurate on the Bafang displays. ThAnks for the reply . Or only when you are really pushing it? To maximize range, you should pedal along in the assist level that gives you just enough power so thats is still comfortable. Wenn das Programmierkabel nicht eingesteckt werden kann oder die Software es nicht erkennt, kann ich davon ausgehen, dass es auf diese Weise nicht neu programmiert werden kann. https://electricbike-blog.com/2017/11/23/i-void-warranties-hacking-the-bafang-ultra-max-mid-drive-ebike-drive/ could it be bad for the motor to run 100% speed limit.

Unfortunately the Bafang throttle can feel a bit jerky. A tag already exists with the provided branch name. My engine is 350W and 36A of batterie (everything is the same as before). I ordered the EggRider V2 it has an Android app for changing the setting. So the max current should be 13A. Only increase the settings in small steps and do intermediate test. And can you tell me what the current battery voltage it, when it states 50%? Can you a Good luck! Alternately it is also attached as a .ZIP file you can extract the .bin file from. Thanks for reply. Greetings I have installed your configuration and Im enjoying the ride. The Bafang motor is meant to be a closed system. The debate is launched on this configuration and / or the ETH1861 with M400. I understand your question. It only works with the Bafang BBSxx series. Therefore I think that the efficiency difference in different gears is not that big, but in general, a lower gear will be more efficient. Will this scenario cause motor damage? My question is this: I have just bought a bafang 500w mid drive motor with an 850c controller. Can I plug n play a throttle without reprogramming the controller, 2. I have a BBSHD with a 48v battery, Gates belt drive, and Sturmey-Archer internal 5-speed hub. nicht. You therefore would be better of buying a 36V 250W BBS01 bafang motor. If you increase the power, the torque will increase, but the speed will increase as well. You should check all physical connections first. http://s.click.aliexpress.com/e/_d6qjlWU. 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 is just the limit of the bikes gearing, they were in the first place never designed to run at speeds above 50 km/h. Assist 6 -current limit 80 speed limit 70 Assist 8 -current limit 90 speed limit 50 Assist 9-current limit 100 speed limit 40 In this way on level 5 of the display I have the maximum current with a reduction in speed I also confirm that the two modes of the ECO / SPORT display are exactly the same except for the color change. It definitely drops almost immediately like is related to a setting. There are only a few IGHs that can withstand the power of a BBSHD/BBS02, most of them will simply wont be strong enough. So there indeed doesnt seem to be anything wrong with your battery. Tongsheng TSDZ2 Review Should you buy it? About the second question. Because the programming cable uses the plug of the display, the display and buttons ofcourse will not work. Only execute the procedure yourself if you are confident that you can do it. Some moisture in the controller could have caused this strange behaviour indeed. Any advice you have on why this is happening would be greatly appreciated. Thanks Giel , that answers my question . Click File in the left top corner of the program. The voltage level of the battery goes down nonlinearly, the software of Bafang converts this to a battery percentage level. I was thinking about this instead of swapping bikes or not being allowed to ride on public roads with each setup to and from. It, in turn, will decide how fast the e-bike will accelerate. So speed is not my priority. What the stock settings were does depend on where you bought it. So there really is no other way of doing it than changing the setting in the display, this should just work. I dont see that you did anything wrong that could cause the controller to break completely. Thanks always start in 1st then shift up just like a transmission. If you have a newer BBS02B you are probably fine, if you have an older controller it might not be a good idea to flash this firmware. You indeed will need the datasheet of your specific cell type. Download When you disconnected, the firmware might have only been uploaded partially. So in that case, the 52V, will be the only option. I get that you can use throttle to power through hills in short burst but that still means I have to be in PAS for throttle to work. This is how the controller calculates speed. Next to that, the problem should also be present before the controller swap in that case. Thanks for your efforts on this. De eco en sport modes zijn niet te configureren. I am talking about these extreme situation. If all this didnt change anything, my only guess would be to purchase a new programming cable. There likely is something wrong with stop delay, stop decay or current decay setting. 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 So set this setting to the desired cruise control speed. It has just been installed. Thank you. Just make sure that you program the 5 assist levels in such a way that they give good control. Hi, Thanks for all the effort you put forth to help everyone. Helpful getting started, but the download is missing some files. 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? I search everywhere and cannot fine if I can use a 48v battery on it. Hi Giel, I have just purchased a BBS02 48v 750w (with 25 amp upgraded IRFB3077 mosfets controller) with 850C display and 48v LG battery. I have a BBS01B, could that be it? 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 I meant if we should do some service work with the motor after maintenance, during exploitation, open it, check smth, grease. I was able to go from 20mph to 23mph just based on your settings here. Is something corrupted? I have built many custom pedal bikes over the years and know a few things about bike building. I was wondering if you know what is the *stock* current limit for this model? 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. Thanks for your help. I just bought a new electric bike with RM G05.250.dc motor. I am away from the bike at the moment. Bafang's release firmware is a moving target so if this changes I'll amend this note . Selecting the correct gear when riding is also important to maintain control of your bike.
