I'm saying this after putting the bike together and it hasn't caught fire or anything, but the battery pack building is making me cringe a little. I took too much off of the plastic cases that not just protect the terminals and stop them from bending but keep them from shorting to another, which would cause a thermal runaway condition if that happens. And burn the garage down. The only thing preventing that now is just a little strip of foam, which might not even be high-temp resistant and now that foam has shriveled up for all I know. So do not follow my example! And I think I'm going to rebuild this somehow, or at least take it out and inspect it.
Great video! We just built a lithium battery bank for our sailboat that we live on. The full video was just uploaded on our channel and we would love to hear your thoughts
that's awesome! We'll have to meet up at a show or something. Any good shows coming up? I'm planning on being at the DGR in September. This EV project should be done well before then or somethings wrong haha.
That's a good question. My intention is to not drain them enough to generate heat. This foam and vinyl wrapping method is very common in ebike battery pack building, and this is even the method recommended by DIY battery book that I bought and followed.
Please let us know what happens with that hub motor. I was thinking about one of the 12kw hubmotors from qsmotor but everything about that one you received looked screwed up. Also considering sharing links in the description for the parts you are using. I'd love to look into the BMS for instance. Love the build
It's working great. Been riding it around until it got too cold out. I was able to get the dent in the rim pressed out by a hydraulic press, and it's not out of balance or anything. But QS sent me a new rim anyways, and they also sent me the brake kit, so they made it right.
I just had the rim repaired by a shop, he used a large press to push out the dent in the rim, therefore the rim was not re-laced to the hub with a better spoke pattern. Unfortunitally that is as far as I have gotten with this project! Shortly after the video, I started building a new workshop which has taken all my time, and two months ago my wife gave birth so now I don't even have time to work on completing my new workshop. But this project is not over! I will get to it sometime this year! Hopefully this winter.
I just got started working on this project again, after spending a year building a new workshop. I painted everything on Saturday and I'm almost ready to start putting all the parts together and wiring it all up
@@ThisOldJalopy or this.. But I would try 100 psi transducer. The link is in comments. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-vMoQwY5WrwQ.html
@@ThisOldJalopy But you need controller with variable regen for that to be an alternative to the physical rear brake.. If you set it at certain level. In wet you could have wheel locking up..
@@Ray88G I can configure the rate of the regen in the controller's software, but I don't think I can wire it up to a variable resister or whatever. It's just on or off. Unless I'm mistaken (controller is a Kelly KLS7245N)
Thanks for asking, I put this project on pause while I built a new workshop, but now I have started it up again and have made a lot of progress. I am ready to begin wiring everything together. Stay tuned for a video coming out soon!
