    Controller for Bafang 750 watt motor

    It’s like I’m first person in history to pair a controller with a Bafang motor. They are actually a very popular motor manufacturer. Have zero people done this?

    Controller for Bafang 750 watt motor

    Thank you so much. That is certainly a lot of information. I am interested in wheel building. However, I mostly wish I could just get a new controller working...like really really soon. I HAVE NO OTHER WAY TO GET TO WORK. I'm thinking now maybe I should get a Kelly controller because of...

    Controller for Bafang 750 watt motor

    I said 3 wires because I have one wire that looked initially like it just had 3 female ports. I think I was wrong. I think that extension cable shows all the wires. I went ahead and ordered it. IS THIS PLUG ON THE SABVOTON 72100 A "SIX PIN 'JST' PLUG"?

    Controller for Bafang 750 watt motor

    "What kind of use is this cargo bike on and how many people and pounds are you pulling and is it flat land or hills?" I GENERALLY RIDE IT TO WORK ON BIKE PATHS. MAYBE 1/3 OF THE TIME I'M ON THE ROAD WITH CARS. MY COMMUTE IS NOT HORRIBLY HILLY. WHEN I WAS RUNNING A 35 AMP BOLTON CONTROLLER I...

    Controller for Bafang 750 watt motor

    For the record I did not do the crappy solders on my XT-90 that broke. It came with my battery.

    Controller for Bafang 750 watt motor

    Thank you so much for your attention to my problems. Again exactly which “controller” I “seal up” is where I am at. Right now I’m still looking at the Sabvoton 72100 the most just because I do not have a PC to program a Kelly. Kelly seems to have 2 levels of waterproofing though.

    Controller for Bafang 750 watt motor

    I had an XT90 connector originally. It had bad solder points and it broke on the way to work one day. They seem fragile. I had to wire nut stuff together just to get to work. After that I talked to my Electrical Engineer friend and I moved to 55AMP Anderson plugs for my battery. Same goes...

    Controller for Bafang 750 watt motor

    I was being too simple. I know it's not that simple. I'm just a few months into this. I'm learning about mosfets, thermal rollback, understanding phase amps more, and a hundred other things. I took an electrical engineering major for a couple years and switched majors. I hate that I have to...

    Controller for Bafang 750 watt motor

    I’ve looked into getting a new motor extensively. Received many quotes. Trust me. I have a very custom wheel size. 18” Rim, 22” inch rubber to rubber diameter. I plan to evolve my bike in the future to a whole new motor/battery/controller. And in fact I have a few suppliers for a whole new...

    This is super helpful. Thank you. Did you see what they said though about my 3 wire motor?
