    Issue with regen from old phaserunner to new phaserunner on bafang BBSHD

    I replaced a dead phaserunner MT that I used with a cycle analyst on my Bafang BBSHD with a newer L10 v6 phaserunner. I would've used a direct replacement but the old MT is not for sale anymore. This wiring harness worked just fine after replacing the anderson connectors for the motor phase...

    Good circuit breakers for batteries?

    I was curious if anyone had recommendations for good circuit breakers for batteries? I noticed anything liquid resistant is usually fro 24/48v marine stuff. I have three 20S10P batteries running in parallel, all connected to this bridge rectifier...

    kp/ki experimenting, controller explosions, and how to prevent them.

    Hi, I have an ASI BAC800 that was programmed by ERT. It was waaaaay too aggressive - it would make this "ga-ga-ga" sound while starting and act like it wanted to rip the chain with every engagement. It sounded like an angry midget with a sledgehammer was bashing something rather than a motor...

    ASI BAC855 not communicating with a 750c or 850c screen.

    Hi, I've tried using this controller with a 750c screen that it once came with(from Alan at ERT), and an 850c screen I bought just incase my 750c had went bad. Neither work, with a new controller. 1) I have connected the controller to the computer and used the bacdoor app to change parameters...

    Screen connector for those BBSHD screens?

    I have a BBSHD screen and I want to hook it up to an ASI BAC800 controller. I would like to stick with the original connector that was on the screen - so I need to find the alternate end. What is this connector called? I can't find the name anywhere. I attached a picture. I would love to use...

    ASI BAC800 programming over USB-Serial interface - possible to use different cable?

    This has standard 5v, ground, TX, and RX. If I open up the USB-Serial cable that comes with a Sabvoton SVMC72150 and change the connector so I can wire it up to the ASI BAC800 TX & RX pins, can I attach it to the ASI BAC800 and get it to work? Or is there more required? I am using the...

    Sabvoton 72150 stuck on hall sensor test.

    I have one 72150 that works great after finding the proper combination of hall sensor wires to phase wires. I have another I got - same look, except this one has the multipin green connector on it that goes to an LCD/button control thing. It's pretty useless as all it can display is amperage...

    My Shenzhen Foxell Technologies battery

    I had a great EM3EV 149SP battery. I wanted to try something with more power. I can fit a wider battery, but not longer/taller battery into my bike frame. Being stuck at 52v/42 amps was something I wanted to upgrade from. I found a seller that would make one of similar size, but much wider, so...

    BBSHD hall sensor plug/connector, what is that plug called?

    I am trying to use a BBSHD with another controller. It works very well, but the hall sensor wiring is a point of contention. I used the wire/connector from my old controller and hooked it up to the new one, but I get frequent hall sensor errors. If I tap on the connector/plug and restart it, it...

    Sabvoton 72150, low throttle very unsteady. How to tweak?

    I am using a 72150 with a bafang BBSHD. With an ASI controllers, if you push the throttle gently, it will move the chainwheel slowly. With the 72150, if you push the throttle gently, it will move it slowly until it hits a certain RPM, then it stops, then it starts, then it stops, then it...

    Bafang BBSHD meets Sabvoton controller - hall and phase wiring color code

    I tried a few basic combinations and it fails the hall sensor test for each. Before I go through and try every combo of wiring, I was curious if someone already knew. If not, I will post back here once I know the correct wiring, after trying the 27 different possibilities. Thank you!

    Programming a Kelly controller for a BBSHD?

    I have a kelly controller lying around, and I wanted to try it out with a BBSHD. Not to its full potential, probably limited to 40-50 amps once set up. The only setting I've messed with so far is to allow it to be used with a different throttle type, and limiting the current to 10 amps so that...

    Axle & tire question - where to find these?

    I am looking for two things. Tires My friend has these amazing 27.5"x2.8" as a substitute for the mountain bike tires since he rides it in the city. I love these tires, but can't find anything like them: they are both road friendly, and fit well on a bike that came with 27.5"x2.8" tires...

    Kelly KLS7230S controller "pedel error" issues

    After setting up a KLS7230S controller, and attaching it to the control box and tablet, I get pedel error anytime I engage the throttle and the motor does not move. I have used this same Bafang BBSHD motor with an ASI BAC800 as well as a stock controller, and it does spin. What does pedel...
