    BMS Rear Rack Battery Anyone tried it?

    I have the 48V15Ah Li-Ion battery with rack on the back of my Schwinn cruiser. The battery itself is almost 15 lbs and I think more than half of the weight is mounted behind the rear wheel centerline, and it definitely affects handling. There is far more weight on the back wheel with me, the...

    Broken spoke. Where to buy?

    I have been using Holmes Hobbies online to slowly replace all of the drive-side spokes on my cheap Chinese built motor hub wheel. Interesting to hear that not having matching spokes exacerbates it. I think I only have a couple of the originals left on the driveside so just waiting for those to...

    Fourth pin on Spicy Curry XLR Connector?

    I have a Spicy Curry mid-drive cargo bike that I would like to make a battery charger cable adapter for so that I don't have to hunt for the charging port when the bike is up against a wall. Problem is it uses an XLR connector that I have never seen before. It looks like a standard 3-pin...

    Source for 5V from S12S Controller?

    This is an interesting twist. I did receive an LM2596HV board and tried it following Joss' plans. It burnt out after a few seconds, presumably from the high 54V being pumped into it, although it should have been able to handle it. I also looked into this issue and found the YouTube video...

    Source for 5V from S12S Controller?

    Update for the team. I got the DC-DC converter and I think it's going to work. I tried using AC-DC USB power adapters but I got mixed results. Between an Apple, Amazon, and a Blackberry adapter I couldn't get them to work with the 48V battery. However some other adapter I had lying around...

    Source for 5V from S12S Controller?

    Thanks for the input everyone. I've ordered the DC-DC converter that joss recommended and I'll try that route. Does anyone know if there's room inside the S12S controller for the converter? I was in there once before and thought I remember seeing room but I'm not sure. What is strange here...

    Source for 5V from S12S Controller?

    I have an S12S controller with the LCD-3 display. I've decided on going with a 5V USB LED handlebar light with an on/off switch. That means I just need to wire in a female USB connector to get 5V from my controller. I am not using the PAS or speed sensor connectors so those seem like viable...

    Bafang CST Motors and elifebike.com

    I wanted to report back on how my build has turned out. I ended up getting the Bafang 36V, 500W CST motor on a 700c wheel. I've paired that with an S12S controller and a 48V 15Ah Li-Ion battery. Let me tell you, it moves! Full throttle on the flats is about 31mph (me=180lbs). Plenty of...

    Lights on S12S Controller with S-LCD3 Display

    I am using an "S12S 500W Torque Simulation Sine Wave Controller" from BMSBattery and an "S-LCD3 LCD Meter for S-Series Controlers" on my bike. The LCD meter has a backlight function that also appears to control headlights and taillights, but I don't see any output on the S12S controller for...

    Bafang CST Motors and elifebike.com

    I am so close to pulling the trigger on an ebike kit based on a Bafang rear CST motor... but I am baffled by the choices at hand. Ultimately the bike will be 48v, 700c wheels, 15Ah battery, 9-12 FET controller. I would like to be able to ride 25-30mph on flat without pedaling. So elifebike...
