The BBS02 also has a new 24A controller instead of the old 25A. 3) power on battery On bike You could set the battery indicator to voltage instead. Good luck reprogramming your Bafang system! So you should attach it to the 26 wheel, or set it at 20 in the settings. I would just keep the current limit of PAS 0 on 0 however. So completely wrong. If I know these numbers, I will be able to tell you if gearing/small wheel size is your issue. This feature protects your battery and is essential to have. This will only be needed if the motor is very old or used a lot. So if you want to know your actual battery percentage, you should stand still and wait a bit for the voltage sack to disappear. You will blow up the controller, so dont do this. Installing this firmware will void your warranty. 10- Plug ebikes battery into BBSHD, but do not turn on the battery power; You can always set the speed limit on the display to 25 km/h. Furthermore, I would just recommend leaving pas0 on 0% current limit. 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. This differs from seller to seller though, so there isnt really a stock current setting in the firmware. If you decrease slow start, you will accelerate faster. This could be the reason for the error code 30 as well. The battery is completely empty at around 41V. You can always try to get the chainring as close as possible with spacers, custom adapters etc. Its always hard for me to pinpoint the cause of the issue you are having. 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? A lot of settings can be applied to the BBS02 36V 500W as well. If you want the e-bike to limited to 25km/u, select 25km/u. Die Mglichkeit, dass Sie etwas braten, ist dann ziemlich hoch. The little magnifying glass does not offer me other COM. I want max available throttle but still VARIABLE on all PAS. It indeed can help other people, so thanks for that. What is your biggest front gear? The reason why it doesnt show up on your computer has probably something to do with your drivers. If you decrease it even more, the pedal-assist wont work at all anymore for some reason. Will thry original software today. So if the current limit is set low, the motor will not be able to turn the chainring with a lot of force. Which often is more accurate than the display does. You dont always get this notification though, so that can cause compability problems. The only setting that works is 1, again default. If the motor is running at 90RPM (at the chainring), it will be pointless to pedal along at 60RPM. Yes, the programming software, actually the internal controller firmware limits the maximum to 30A. If you let the motor do all the work when it does not have enough power, you could potentially damage it. Apart from that, I dont see any obvious reasons why it wouldnt work. So I have no clue why your display doesnt change the read out. This is the only setting that makes sense because its convenient to be able to change this in the display settings. Can you a 3) Mostly explained in 2. Therefore the cut-off will also be hit earlier than expected. There is this video on youtube describing a DPC18 display with the ability to program 3-5-9 levels of assist. The firmware is also compatible with the TongSheng TSDZ2 controller but requires a custom made cable in order to interface with Bafang compatible displays. Compatible with TSDZ2A/B using the STM microcontroller (which is nearly all off them). So I tend to do this less now, therefore my drivetrain also lasts longer. Do you use gear sensor? This is the case with your controller. Yeah think u are right. Managed to fix it by flashing the appropriate bin file containing the correct firmware using stc-isp6.86 and all is now good! So dont change it to something different. stc-isp-15xx-v6.86E.zip Is something corrupted? Refinements being (my favorites, anyway): Thank you for your useful information. This has to do with the highest gear ratio of the bike. No harm can be done. Therefore the display will think that the battery is less full when you are driving. It has a speed limit of 25km/h, but how to make him go to,ex 40km/h!? Use Git or checkout with SVN using the web URL. (Note says that FTDI based USB-serial adapters work well, but I assume you MUST use a USB-serial thats got the right connector for your BBSHD, presumably the round 5 pin green Higo).

Does it not turn on anymore? For a 48V battery, a low voltage cut-off of 41V is appropriate. Are you using a 4K monitor? Have you been able to program that motor using the programming software? For that would you set the current level to 100%, and speed limit to 0%? If you want insane power, get the BBSHD, this motor has a 30A controller. My questions are pretty basic. The Bafang DPC-18 LCD Display is compatible with our Bafang mid-drive motors (BBS01/BBS02/BBSHD) and front hub motors. You should not have to do anything with baud rate, etc. Did the controller fail right after the usb procedure? Changing this setting doesnt do anything noticeable. You are now ready to test your new configuration. Its strictly a feature of the mid-drives. I do not see the profiles or the pdf file. Make sure not to hit full throttle in high gears or on a steap incline. ONLY CONTINUE IF YOU ACCEPT THE CONSEQUENCES OF YOUR ACTIONS! I sometimes notice that my gears slip one teath when coming on power. With this configuration, there are still some problems: sometimes suddenly, and difficulty in relaunching level 2 to 3 or even 4. But getting the exact same settings on there as the old controller is definitely something that you should try first. It isnt worth it to pedal with an unnaturally high cadence to improve the efficiency of the motor just the slightest bit. The tool helps in disagnosis and detecting errors. Does anyone know how to upgrade the firmware on the BBSHD controller and where to get the latest firmware? The 104 BCD adapter is the only way to get a smaller chainring on this motor. I have had bad controllers, but I have never had one fail during or before a reprogramming procedure. Top You should set this to 44 instead of 41 for the 48V battery. 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. always start in 1st then shift up just like a transmission. Close to ordering the programming cable and start having fun with my bike as well. So if you look at it that way, it isnt weird that the cadance at those speeds will not be optimal anymore. The download link wasnt working anymore. This is a safety feature designed to keep the battery in good health. Using this cog I put throttle to max. Be mindful of the fact that you can damage or burn-out your controller if you accelerate from standstill in too high of a gear. You cant damage the motor or controller by setting the amp limits to low values. But as explained in the previous comment, the 36V battery will not work with the BBSHD. If you want this, you should set the current limit on PAS 0 to a value different then 0 (depending on the power you want). Battery is 5 years old but seems normal, issue only started after replacing old burnt out controller with a new Luna controller. I tried to connect with my desk top instead of labtop and quite the same problem except that COM4 is available when i connect the USB cable. You now have created a back-up you can use later if problems occur. Therefore I think that the efficiency difference in different gears is not that big, but in general, a lower gear will be more efficient. Thanks for the suggestions. I found that this way the motor responds a lot more like you would expect. Or does the display still work? And what is the gear ratio of this single gear? Just my luck. Baud rate, etc? I also recommend increasing the Current Limit [%] 10% at a time. I also found a company who delivers a reflashing service, they are however based in the uk: https://www.electroncycles.co.uk/product/bafang-bbshd-controller-re-flash-for-52v-up-to-60v-service/. When we ride with PAS what gear should we choose: as we usually do without PAS to ride with cadence 90 or more or less to get maximum efficiency from the motor? I am glad you asked to check it, because the Bafang programming cable will not work with your hub motor. Hello Giel, Herve 6 Select the Com port that was assigned to your preferred USB-Serial Adaptor. it was a defective USB cable. Full Color LCD Screen with updated sleek speedometer design. The only reason I ask this is because I think that was the default and I test rode it before playing and finding that I can change the voltage to 52V. I was able to go from 20mph to 23mph just based on your settings here. Bafang BBS02 and BBSHD Programming Cable $19.95 Share: Sold Out Compatible with the Bafang BBS01, BBS02 and BBSHD 1000 kits Access the custom program settings to dial in the performance of your drive Make your factory drive as fast and as responsive as you like it. Received my cable today. Have you tuned an Ultra yourself before? 28 wheels There may be a lot of that back and forth till i get it right. That assistance will draw a certain amount of current, which will determine your range. I will keep looking and I will try another LCD. Any other suggestions? Here is an excellent write up on programming the Max drive M400 Assist 1 20 / 100 Solved the problem replaced the controller. BBSHD and BBS02 Configuration (Programming) Resources So try default settings (back-up that you likely made), upload and test again. The reason why your new controller feels slow, is probably because the current limit is set lower. Thank you. You then wont be able to accelerate hard if you are below 40%. 7/88/75 If you dont have e-brakes however, set this to 10. Thanks for your suggestion! You can try to reset to your default settings, and see if it still happens. It would have been amazing if you could reprogram the hub motors as well. 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. I hope that you are able to fix the problem. . I have figured for my needs it is Likely the 750W BBS02 with a 48 V battery 17ah with a 500c controller. It makes a noise, not more than that. Not all displays have this setting, so it could be possible that you dont have it. I actually like pedaling uphills on my own power! So in your case it indeed should be attached on the 26 wheel. This setting decides at which level the throttle will stop. Yes, I reprogrammed my trekking bike (Fischer ETH1861) with the software. Now follow the following steps in order: You are now ready to start using the configuration tool. (19.86 KiB) Downloaded 869 times. Do you think this is sufficient for my needs as listed above? To clarify, do you have a bafang hub motor or mid-drive? I checked all connections. The Current Limit [%] setting specifies the percentage of the current limit[A] the motor can use at that level. Only increase the settings in small steps and do intermediate test. I hope I was clear in formulating the question, I am writing to you from Italy 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? Therefore no pedal power is transferred to the bike. I tried with two USB programming cables I am happy that you like the website, thanks! I recommend this setting to be the same as the amount of pedal-assist levels. Order Numbers should be 6 or less numbers (Examples: 1234 or 123456) Message *. Those inaccurate measurements unfortunately cant be fixed. If you want the pedal-assist to start the fastest when you just pedal a small bit, change it to 2. Set this setting to your wheel diameter, if your wheel diameter isnt in the list, then select the one that is closest to your wheel diameter. So riding along in too low of a gear in the effort of increasing efficiency will create the opposite effect since you then will not be able to put in your own leg power. 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. 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!
