    Single wire high amperage connectors for stator wires?

    The stock motorcycle bullet connectors going to the motor are insufficient and get too hot. I am building a prototype that has an electronics box that has 1/2" diameter cord grips. A few searches led me nowhere regarding single wire quick connectors for higher amperage. You guys have any ideas...

    Any Good 24s LIPO BMS solutions out there?

    I currently have this one http://www.aliexpress.com/item/24S-lithium-battery-protection-board-BMS/1930156282.html?spm=2114.13010208.99999999.264.QpuboM but either the charger or the BMS failed 2 hours into the first charge and destroyed one another. Chinese transistors. Any more reliable...

    Greentime BMS LED lighting logic? LED on for fully charged?

    So I gather that the LEDs come on on the BMS when the cells are fully charged. What about low voltage cutoff? This is my BMS: https://www.aliexpress.com/item/24S-lithium-battery-protection-board-BMS/1930156282.html?spm=2114.13010608.0.98.EoPCrt

    Wiring 4 packs of lipo to one BMS? Diagram included.

    I just got a Greentime 24s BMS in the mail and am about to wire it up to 4 packs of 6s battery packs for 24s. My intuition tells me that I should connect all four small black wires from all four sense wires into the B1- connection on the board and then every cell thereafter into the...

    Motor thumping at high rpms with new 72v controller (VIDEO)

    I swapped out my 48v controller that worked great with a 48-72v 1500w controller to get ready for my additional battery for 66.6v nominal voltage. While the new controller has lots of connectors that the 48v didn't have, I only plugged in the essentials (phases, power, throttle) Well, it works...

    My Velo Pedal Car Prototype

    A while back I decided I wanted to turn a motorcycle into an EV bike. After internet sleuthing I came to the conclusion that wind resistance at highway speeds makes for some expensive battery/motor/controller combinations, and my motorcycle already gets 50mpg+. So I decided to build an electric...

    Using leafmotor/leafbike 1500w as mid-drive motor?

    Is there any reason why I cannot or should not buy a 1500w rear spoke motor from leafmotor/leafbike and mount a sprocket onto the 6 bolt threads for the disc brake for use as a mid drive motor on a velomobile project? What are the threads on the opposite side for? mounting a casette...

    On-board solar charging LiPo

    Building a semi-enclosed, pedal assisted, 3 wheel bike/car and would like to have the ability to plug it in to 110v and walk away. Is there a charger solution that will handle this for me? The batteries will be 4x Turnigy 5000mAh 6S 20C 22.2v Lipo for a total of 444 Watt-Hours. 2 in series 2 in...
