    Winter Project... Design and Build an eScooter

    Just when I thought I was finished.... Took my scooter out on the course this weekend with my brand spanking new fenders!!! Problem was , the fenders turned out to be a little bit short to be totally effective. Well, after washing off all the mud off my bag and golf clubs I made a modification...

    Winter Project... Design and Build an eScooter

    Summertime in Sacramento is quite warm. Consequently, the greenskeeper keeps the course well watered. It only took a couple of rounds with my scooter before it became apparent that I needed to make some changes. First, any puddle or muddy spot on the course immediately earned me a badge of...

    Winter Project... Design and Build an eScooter

    When I started this project back in November, I had no idea what I was gonna do with a scooter once I finished building one :? All I knew was that I wanted to build one :D Well, during this time, the powers to be at my country club decided to allow golf scooters to be used.... So, back to...

    Winter Project... Design and Build an eScooter

    Thanks Dui, What you are looking at in the picture is the crimp on connector for the charging wire (12 Gauge). The main power wire is an 8 Gauge wire that I hydraulically crimped to one of those hi amperage gold plated stereo rings and then bolted to the busbar. Should hopefully have the...

    Today was a great day. FINALLY FINISHED MY SCOOTER!!! :mrgreen: :mrgreen: :mrgreen: Started by completing my battery build. First I quickly milled out a little protective cage for my bms. Next, I cut out some end panels and double side taped them to the ends Then in my effort to prevent...

    Winter Project... Design and Build an eScooter

    Life has a way of interfering with the best laid plans... Unfortunately, one of those misguided events caused me to shelve my scooter project for a couple of months, but I'm back now :wink: When I last left off, I was trying to figure out my wiring scheme. I ended up pretty much wiring...

    Winter Project... Design and Build an eScooter

    So I dove into the wiring aspect :shock: Shoulda been a piece of cake. However couldn't get things to work the way I thought they should. So I took a step back and sat down and created a little wiring diagram. Before I jump back in, does anyone have any comments, corrections, or advice on this...

    Winter Project... Design and Build an eScooter

    So, I started wiring up the lights and hubmotor today. The hubmotor was pretty straightforward :wink: The lights, on the other hand were a bit of a challenge. As you recall I have the ground effects, LED headlights and LED tail/brake lights. They all operate off a 15 amp DC converter that will...

    Winter Project... Design and Build an eScooter

    Not yet... I'm still working out the wiring. Had to figure out a good workaround to light the taillight/brakelight and how to interface the Kelly controller to the Cycle Analyst and the hubmotor. Think I have things figured out and hopefully will finish the wiring this weekend.. :? Pics to...

    Winter Project... Design and Build an eScooter

    Made a bit of progress this weekend :) Ran all of the wires to the dashboard... Then wired it all up... Closed up the dashboard and mounted in place... Finally, this project is starting to resemble the drawing I did a few months back...

    How To Wire a 12V Brake Light and Turn Signals

    Amberwolf, Thank you for your reply. In my haste to post that last post I had a few typos. It should have read 2.2Kohms, not 22 , and 103 not 105. :oops: Thank you for the lesson on resistor values though. It will come in handy. Anyhow, I messed around a bit by putting varying voltages...

    How To Wire a 12V Brake Light and Turn Signals

    Dang, My new 12v opto isolator relay showed up. Unfortunately it has the 10K resistor instead of the 22K one. So back to square one. I could swap in a 222 resistor in place of the 105 one, but it's unclear whether or not additional changes would also need to be performed..... Or, i could just...

    How To Wire a 12V Brake Light and Turn Signals

    Disregard my last post,,, Two reasons. First I think the load placed on the 5V coming through the voltage divider from the relay coil might generate a bit too much heat in the resistors. Secondly... I was able to find a 12V optoisolator relay with the PROPER 22Kohm smd resistor on Amazon. Will...

    How To Wire a 12V Brake Light and Turn Signals

    Teklektik, Thank you for the excellent tutorial. It only took me three days to figure out how to make my relay work the way its supposed to :oops: Anyhow, I have a question for anyone who knows more about circuits than me (pretty much everyone). I am using the 5 volt version of the relay...

    Winter Project... Design and Build an eScooter

    Thanks fechter... It's a QS Motor 48V 1000W V3 motor. I will be slightly overvolting it at 60 Volts, but I'm thinking it should be able to handle it :)

    Winter Project... Design and Build an eScooter

    :D :D :D Thanks for the advice. Actually, I'm gonna build a 60V 35aHr battery with my own two hands. Figured I might as well get my feet wet. Already have my K-Weld and building supplies :wink: Just waiting on my cells to arrive on a slow boat from Poland. Unfortunately, I think I'm gonna...

    Winter Project... Design and Build an eScooter

    Frame went off to powder coaters.. Was gone for a couple of weeks. Unfortunately the scooter was just a bit too big to fit in my toaster oven sized powder coat rig. I did the smaller pieces and left the big ones to the pros :wink: Anyhow, while it was gone, I started to design and CNC the...

    Winter Project... Design and Build an eScooter

    Not a lot of progress lately... Lot's of other things to do in life. I did manage to design a build the rear LED taillight/stoplight, and added a couple of pod lights up front as headlights. Along with my ground effects, there's no way you won't see me coming With lots of cussing and spitting...

    Novice batt builder question

    Got it :thumb: Batteries ordered yesterday after multiple emails with the vender. He says 3-8 weeks for delivery due to luck :wink: K-Weld US seller just got his supply in the other day from Germany, so might be worth a look. Good luck with your build and I'll keep you in the loop.

    Novice batt builder question

    Glad you got it. Don't know where you are located, but I purchased 200 Panasonic NCR 1865PF from a seller in the New For sale section. These are 2900 mAh, so a bit less than you are looking for. The seller has a large variety of new cells and new with welds removed. Great pricing as far as I'm...

    Novice batt builder question

    OK, I'll try... If you take 20 batteries, each with 3500 mAh and wire them in PARALLEL, you essentially get the equivalent of 1 giant battery with a capacity of 20 X 3500 mAh = 70000 mAh or 70 Ah. But it is still only 3.7 volts!! You would need an additional 15 of these same giant batteries...
