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

    That makes sense about the regenbraking. The reason I thought it had something to do with regen braking is because grin did something when advancing from the phaserunner MT to the L10 V6 where they tied the throttle and ebrake together. I wasn't getting any movement when I flashed my old...

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

    I don't have enough to answer your first question unfortunately. I don't have a way to tell RPM while on the bike. I know I am below the RPMs I used before since I have my field weakening amperage set way lower than before, and I am way below the power I have used before since I used to use this...

    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...

    Rewinding BBSHD for 72V?

    I put 72v through mine with 40-50 amps on a regular basis, no modification. No need.

    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.

    Yeah, I tried every protocol down the line. I had a session with ASI and sent them my programming, they added options they thought would fix, no dice. I gave up.

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

    I had a chat session with the good folk at ASI, but no luck. They think it is just a display not programmed for it. Strange since this display works with a BBSHD stock controller, but doesn't work with ASI's BAC855. Does anyone here have a display they use with the BAC855 they can confirm works?

    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?

    Yeah, I know those aren't correct - I am saying that I'd rather buy those and cut the wire off and re-terminate than wait a few weeks for HIGO since you can't buy them in the United States. But apparently you can - the amazon prime listing you showed me is invaluable - I'd rather have that since...

    Screen connector for those BBSHD screens?

    Thank you! I have another BAC855 here that I was going to use on a different build - where the serial connection works. People sell this specific controller pre-programmed with a display, so I imagine there are ways to make it work. I will try and dig that out of ASI support. I noticed that...

    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...

    E.R.T \ Alan Hu nightmare.

    I can't get that to see a controller. Thank you to the anonymous kind soul who sent it over. I do have a login to bacdoor, as I paid for another ASI evaluation kit. I thought I'd try using it to log into this BAC800 and change that setting. There is a parameter access code that is required...

    EM3ev vs Luna Batteries and Kits

    I bought a battery from EM3EV. It had an issue with shipping where they would've been in the clear even if I filed a chargeback(which I never threatened to do, I am just saying that they would've been able to keep the money). They expressed me a 2nd one anyway. When the 1st was found I paid for...

    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...

    The future of our forum - facebook versus web forums

    I completely understand and respect not wanting the place to become riddled with aggravating looking banner ads. I'd be willing to pay for a non-intrusive sponsored spot as we have an electronics-ish company. Not even just so much for ROI, but because I have learned so much from reading...

    E.R.T \ Alan Hu nightmare.

    I bought a BAC800 from him 13 months ago. What I found interesting, was that it keeps going after you turn the throttle off. No controller I had ever purchased does this. It just keeps throttling along at a slightly lower speed after I take my handoff the throttle, cruise control style. this is...

    Sabvoton 72150 stuck on hall sensor test.

    Sabvoton software - I will check it again tomorrow with the battery BMS app and see for sure. I gave it about 20 miles of work today with a passenger riding on the rear seat and it worked great, so all seems to be set. This combo kicks ass. Much smoother than the ASI BAC800... no shakiness...

    Sabvoton 72150 stuck on hall sensor test.

    Should it be troubling that it takes 45 amps to run a hall sensor test? 45 amps is what I am usually using to go 40 MPH with the load of the motor being in the housing/carrying my bike and an actual human - and it is using that for a hall sensor test with the motor/stator outside of the housing...

    Sabvoton 72150 stuck on hall sensor test.

    I re-ran the test, rather than using 15-25 amps for test given current for hall sensor test, I went all out and tried 45 amps. now it passed. I changed it after realizing that at 15-25 amps it wasn't even turning the stator, just a lot of coil whine. With the other controller, even at 15 amps...

    Sabvoton 72150 stuck on hall sensor test.

    I had to undo some of the waterproofing I had added to check the new motor with the old controller, my apologies for the late reply. The working controller works correctly on the motor that the problematic controller does not work on. When I try the any of my BBSHD motor cores with the OLD...

    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...
