Thank you for your understanding @M365Guy. I wish I was born knowing all this stuff, then I probably wouldn’t even be asking anything.
This is the first electric vehicle I’ve ever had besides an old electric razor scooter I had a very long time ago, but it never had any issues or needed service on the razor. Very reliable overall, turned on every time, and never died on me. With this B2 not so much, it’s only been 1 month and so far I’m averaging $100 per mile. I don’t know much about electric vehicles or how they work, but I am starting to pick things up along the way. Unfortunately, with the shop, they won’t tell me what parts I need or what will or won’t work. I know a fair amount about cars and occasionally work on them myself if it’s simple enough. However, it is not really the same thing.
The battery in the B2 does seem very powerful for its size. Originally I thought there was something wrong with it or that I was going too fast since I was only getting 5 miles range which I would think would be higher than that.
That sounds like quite an M365, I’ve seen some of the M365s with zero motors. You probably still knew more than I do now. I’m starting to understand what each component does, I think I may have found the exact motor or one similar for maybe a dual-motor B2 or should I ever need another. Probably not doing dual motors, since it has enough problems as it is with just one motor.

I was thinking about maybe trying to use the factory Texas Instruments Controller DRV8323S Three-Phase Smart Gate Driver, but I didn’t know if that was possible or not. I called them to see if it would, but all the times I called they didn’t answer.
When it was working the motor was a lot more powerful than the razor I had. On the label behind the front tire, it says the nominal power is 400w. I would guess that’s the motor rating, but you would know more than I do about that. I’ve seen a B3 running on either a 1,800 or 2,000W controller at 62mph, but I would think that many watts would be too high, and the motor sounded somewhat stressed. I’m not sure about what kind of axle it has, but possibly similar to that 10 inch brushless motor for sale.
Thank you @M365Guy I appreciate it, that controller off amazon should work. However, I was wanting to maybe go with one that’s maybe a bit more high quality, since I don’t want to keep doing a $258 controller install each time.
I was wanting to get a 36v to match up with the battery and probably 21 Amps max so it doesn’t trip the BMS.
So far $881 to be exact, not including parts, controllers, step-down converters, push-button switches, new B2 headlight, two new B2 taillights, new bird neck logo stickers, new bird logo stickers, new “no sidewalks” stickers, and new front and rear reflectors.
Lol, I definitely wouldn’t describe it as low cost at this point, pricey is a bit more accurate at $100 a mile so far. Unfortunately, since the shop isn’t telling me what I need or what will or wouldn’t work I’m not able to learn too much, at least from them.
$258 is just for the controller install, not including wiring, stepdown converters, installing the new taillight, or any of the other stuff. I would probably be able to do it, I just didn’t want to mess up any of the wiring, soldering, or anything else that could go wrong.
They did say this time they would be able to install a fuse from the controller to the battery, so the fuse blows instead of blowing the controller again. I’m in Arizona though, most of the shops probably about 97% of the electric vehicle shops only work on their own products or solely electric mobility scooters. Out of 70 I called, I only found 3 shops and one guy that would be able to work on it. The first shop said they could when I called, and said they could when I drove down and showed them a picture, but when I brought it down they said they couldn’t. The second shop was talking about the upgrades they did on a hiboy s2 pro and I said I'd want to bring it down to get it fixed. The phone went dead after that and just a dial tone every time I called back. The third shop is the one that finally was able to work on it and the mobile mobility scooter guy I still haven’t ended up using.
