    How to connect a DC to DC converter?

    Hehe, quite expensive hour rate lol. I think I have to stick with the 5 amps fuse because I plan to add the magicshine MJ-880 light on it: Magicshine MJ-880 Bike Light Torch LIGHT UNIT 2000 LUMENS!! upgrade from mj-872 | eBay This light is small but very bright. That's exactly what I'm...

    Use led light for warning signal

    Thanks Rog for this detailled explanation. I just purchased the led from Hobby King as they may be appropriate. Which resistor should I buy in order to get it work? Also, you mentionned that the flasher unit froml Oigoi may work. So if I get this unit, could I directly make my hobby king led...

    How to connect a DC to DC converter?

    Thanks a lot guys. I finally made it work. I have my switch turn on multiple lights at the same time. I used the multi-meter to check for continuity between the cables as you said NRJ. And I found that the light and the 3 speed switch cables all have their own "ground". So I plugged...

    Use led light for warning signal

    Hello there, I'm looking to use warning signal for my bike, but with a very minimalist set up (less visible is better). So I'm thinking about using these led strip: HobbyKing R/C Hobby Store : High Density Waterproof LED Flexible Strip - Yellow (1mtr) Combined with a car signal controller...

    How to connect a DC to DC converter?

    Thanks for the explaination. I tried this: So it's using the ground from the controller and the power from the DC converter. But there is no power at all. I tested on the wattmeter and there is 0 V. I suppose I missed something, but I don't know what

    How to connect a DC to DC converter?

    I had it from Lyen. So far I can't tell if it's working well or not because I'm only using the horn button as regen. All the other cables are not connected. If you know any better switch I'm interested :)

    How to connect a DC to DC converter?

    yes, but 1 ground cable will go through the controller. The voltage is 74 V. And the other ground is from the DC converter at 12V. So with 2 different ground, I'm not sure I can mix the wires (use the light and controller functions at the same time) ps: Anyone know any cheap electric store...

    How to connect a DC to DC converter?

    Yeah, I know. I don't have much knowledge in electronic but I'm learning. That's quite satisfactory to be able to achieve thing by myself :) I now want to connect the light to my 3 speed switch: The problem is that my actual 3 speed switch is already connected with my controller: The ground...

    36V vs 48v efficiency.

    You can check different setup directly on the simulator: ebikes.ca Hub Motor and Ebike Simulator The closest motor to the G209 is the crystalyte 406. If you plan to stay road legal, you better have the right voltage for your speed. So that the motor would be at his max efficiency. If you...

    How to connect a DC to DC converter?

    I'm just using hobbyking led strip for now: HobbyKing R/C Hobby Store : Turnigy High Density R/C LED Flexible Strip-White (1mtr) But I'm planning to use the standard 8.4V light (magicshine or other) to plug on my 12V DC-DC converter. There is a voltage difference but when a battery is fully...

    How to connect a DC to DC converter?

    I finally plugged in to my battery cable: It seems to be working (but I only have around 8V output). But the main problem is that with the converter plugged, I've lost 12V on my bike!! I went from 76V to 64V displayed on the cycle analyst. I had a huge voltage lost. Is it normal? I thought...

    How to connect a DC to DC converter?

    I'd like to use my bike battery for my lights. So I'd like to connect the converter between the battery and the controller. If I connect the red and black wire to the battery, it would be a closed circuit. I'm wondering how I can have a "loop" between the battery, controller and dc/dc converter.

    Folding electric - Wisper 806 or Brompton?

    Quite interested on the performance of the G209. 20A shouldn't be much for this 4 kg direct drive motor. You're only at "700W". I believe you can even go to 1000W continuous. So even 25A should be ok. I have a similar motor (conhismotor mini hub), it weight 4.6kg and is direct drive. It...

    Brompton electrification

    Update on the brompton: With my little conhismotor mini hub at 4.6 kg, I do peak at 2500W and he handle it without breaking a sweat. But I only use that much power for acceleration and I don't cycle very fast (17-23 mph). I'm actually running slower than my actual "limited power" bike. Most...

    How to connect a DC to DC converter?

    Hello there, I received today my 12V DC to DC converter: Zenid e-Bike Parts But I don't know how I could plug it to the bike? Usually there is an input area and an output area, but here there is only an input?? Any idea how I can do that?
