    bbshd problem - driving on walk assist but not on throttle and PAS

    By second thought, Does anybody know if there is a way to check if the PAS controller works from a BBSHD preferably without opening the motor. The only thing I can think that is broken is the PAS controller itself (I mean the magnets turning around inside the motor), this is separate from the...

    bbshd problem - driving on walk assist but not on throttle and PAS

    Hi, I am wondering if somebody here has had the same problem? I upgraded my Bullitt from a bbs02 to a BBSHD with a new battery. ( 14s7p) It drove perfect for some weeks, after some weeks I got intermittent power. I thought it was my battery (4 years old) and replaced it with a new one from...

    14s10p non welding DIY battery

    I agree with most of it, problem is i am loading the battery on my bike. The reason i was asking, i was not sure if the casing would melt, in case of melting i agree completely this would create a bigger hazard. There exist a kind of paint that foams up in case of overheating and creates thus...

    14s10p non welding DIY battery

    Making the final drawings for the battery. I have one question about the casing of the battery. There is always a risk of fire with li-ion batteries, this risk is already much less with a good BMS, but still, there will always be a risk. Originally I was thinking of making a polycarbonate...

    14s10p non welding DIY battery

    thanks for thre reply, I suppose I will take it as a standard to load it till 80% SOC except when i need a longer drive. i can afford to load it less, it's big enough, but when i really need the distance i load it for 100%. I would go for the LG M36, because of the good reviews they got in the...

    14s10p non welding DIY battery

    I am in doubt between the samsung 29E, 50E or lg m36. They all have a great recharge cycle, if not charged and discharged too hard. Because I would take a big pack 14s9p or 14s10p charging and discharging shouldn't be an issue. Normally I have the habit of loading my battery pack for 90 percent...

    14s10p non welding DIY battery

    It was a battery from em3ev. it was a 14s8p battery 52V. They don't offer that type anymore. I am very happy with their service. Only it becomes so expensive to import them to Europe. If i want a similar battery (14s9p) it will cost me roughly 1000 euro with taxes. If i make it myself it will...

    14s10p non welding DIY battery

    I am planning to make my own system, looking around here, to learn from the mistakes and the success stories from others. But for bigger packs i didn't find a good enough solution yet, that's why i am making my own design.

    14s10p non welding DIY battery

    Hi, I am planning to make a battery for my bullitt. The weight is not that important because it is a cargobike and the battery will be placed low in the bike. I have a bafang bbshd and my former battery died on me after 6 years of service. This was a 52V 14s8p of 21 AH. I would like to improve...

    New Bafang Crank-Drives

    @ finnen If you don't mind programming your own bafang, i would take the 750W motor and tune it down to 15 or 18 A. In this way you have roughly the same performance as the 500W with the possibility to tune your engine up to 25A in case needed. I drive myself a bullit bakfiets with a 750W tuned...

    Programming the Bafang Middrive BBS01+BBS02

    Thanks for the confirmation. my idea is that i have two or three different topspeeds. So i am going to try something like: with maximum speed 50 km/h PASlevel: current limit % - speed limit % PAS1: 30% - 50% PAS2: 55% - 50% PAS3: 75% - 50% PAS4: 100% - 50% PAS5: 30% - 70% PAS6: 55% - 70% PAS7...

    Programming the Bafang Middrive BBS01+BBS02

    In the programming tool on the basic tab you have the second column Limit spd(%). Is it meant to limit the speed in that particular PAS-setting to a % of the topspeed set in the display? eg: My topspeed in the display is set at 40 km/h. In the programming tool in PAS1 i set the limit Current...

    Programming the Bafang Middrive BBS01+BBS02

    other question: Is there a way to program the BBS02 in such a way that different levels of PAS can have a different topspeed. eg: PAS 1 - 3 max speed = 20 km/h PAS 4 - 6 max speed = 30km/h PAS 7 - 9 max speed = 50km/h

    Programming the Bafang Middrive BBS01+BBS02

    Is there somewhere on this threads a list which explains all the different values of the programming tool and their impact? At this moment i am driving only with PAS, but every time i reach my topspeed the assist would stop and the speeds drops, when i then have to change gear, brake or...

    New Bafang Crank-Drives

    About the so called wobble some of you feel, i feel the same when i start the bike in a high gear. It is not really the shaft wobbling, but the engine which is pulsing, because it is not turning fast enough i guess, the moment the motor revs up the pulsing disappears completely. About the...

    New Bafang Crank-Drives

    I am sure i have read somewhere on this thread it is possible to connect a 2-wire brake instead of a hall sensor brake to the bafang bbs02. Does anybody know how to do this or where the post is? thanks EDIT: Found a solution...

    New Bafang Crank-Drives

    Of course depending on where you live: But as already mentioned numerous times before i think Em3ev (http://em3ev.com/store/index.php?route=product/category&path=45) is indeed one of the better and trustworthy suppliers. You can buy at Chinese prices, but with a very good customer response. As...
