Connectors and Voltage

[Gionnirocket]

I am pretty sure California Ebikes told me a few weeks ago that all the motors are pretty much the same with different programming, so I'll see if they tell me to just program it differently with the Eggrider. They promised they'd take care of me when I told them I wanted the new motor from them, and I trust them.

In very general terms... Motors can be used in a range of voltages, though if not at design voltage, efficiency can suffer greatly.
That said the bigger problem here is the internal controller.. that more than likely should not be used out of voltage range.That's why the manufacturer sells them as matched sets. The MOSFETs most importantly may have a voltage range designed to work with the particular motor voltage.
So yes... Patience little grasshopper. You're spending good money and you should want/get what you paid for.

A 48V BBS02middrive motor is going to need the LVC lowered to run on 36V, if that is possible with the programming cable, and the hardware . I've seen the box for the LVC in pictures of the programming screens, but don't know that the hardware will follow it.

I know that mine shuts off around 42V, which is the top of a 36V battery,

LOL. Yeah, it's crazy, and I came in not being someone who knew anything about bikes. But I'm learning a lot. I also have non ebikes I am messing with. I had people from Facebook give me 6 bikes in various states of ruin and I've been tinkering. It's fun.

Never got the PAS working on the original BBS02?

Working on ebikes, soldering is a good skill to have. Then again, some people tell me I should have learned how to weld 20 years ago for my old cars, I wish I had. I'd have some giant flamingo sculptures on the lawn.

You're correct the software does allow you to enter a lower value... but having never tried to do it I'm not sure if the hardware will accept it.
I can't remember off hand which settings I was playing with, I believe it may have been Keep Current. But I remember trying to alter a setting and setting a value of 0... but after applying it and then going back and reading it off the controller it defaulted I believe to 1.
In any case, I'm a little confused on why anyone would want to do this, especially with brand new hardware.
If on a deserted island and no means of matching a battery to a motor with nothing to lose, sure why not try.

Well, I heard from California Ebike today, on Easter Sunday, so maybe I can't blame Good Friday for them not being around this past Friday.

They said that I do NOT want to run the 48V motor on a 36V battery, and that the connectors aren't compatible.

With a few other things in mind, I decided to order a 48V battery, that has the right connectors as well, and I am going to try to fix the old motor by buying a new PAS circuit. I need to watch what I call "worst case scenario" the way things have been going, but it seems like likely the worst thing that happens is that I end up with a worthless 36V motor and some extra parts and a 36V battery to sell, and a working 48V kit, since I trust California Ebikes to stand by their products.

Best case is I end up with 2 workings kits, and I have a friend that would buy the 36V kit from me.

Either case, I think I am going to save my sanity and never talk to Greenergia again.

What an adventure this has been! I hope I haven't thrown away too much money, but I sure am learning a lot about batteries, electrical connectors, and buying from reputable sources! It all started with a FOMO purchase. Whoops.

Another expensive lesson in life...but if I come out smarter in any way, that's a win. Haha.

Very good attitude and you did the right thing waiting for California eBike to get back to you.
That said... 48v is the way to go with the BBS02B anyway... I think you will appreciate the upgrade.
Why can't you just get a refund from Amazon for the 36v kit?
And more importantly.. You can file a dispute with your credit card. You will most certainly receive a refund from them especially since you can prove that you tried to work it out with the merchant. Don't give up too quickly on losing your money.
Good luck and Happy Easter!

Thanks man. Well Greenergia seller offered me a refund for everything but the battery, and I'd have to send it all back, or they'd exchange the motor only. Neither sound like a good option to me. I wanted a refund for just the motor and to keep the rest. I've used glue and such to attach things like the ebrake sensors, and I imagine them dinging me on the cost of that. I just want to never talk to Greenergia again. I am tired of it.

I am going to contact Amazon and see if they'll just give me some money back without going through Greenergia any longer. We shall see. And yeah good idea to contact the credit card company too if I have to.

Also, my job is a sales job with commissions, so the more time I spend on this during the week, the less time I have to focus on making more money, so there's that too.

Happy Easter to you too.

I guess maybe I will try the "motor only" exchange but I had opened the motor as well to try to fix the problem, and I am concerned they'd try to ding me for that if they notice! I'm just so over it.

I hear you not wanting to waste too much time on this.
In order to get a refund from Amazon or your card you will need to return everything... Though a PitA... That is only fair. I can't see them banging you as this is a DIY kit and it must be installed in order to make it work.
This way you can just start fresh with a all new 48v setup. If the motor and battery were sold as a "set" .. They must take it back as a set.

Well then there's issues with shipping batteries back because of the shipping challenges. I don't think they take returns of batteries at all. So that's the root of it. It's a mess.

 

[Gionnirocket]

They "should be" responsible for the shipping..battery and all on a defective product. Do you still have the box and packing?
I guess see what Amazon and your credit card say about returning it in its entirety.
You can always fall back on keeping the battery and getting a replacement motor and selling them as a set.

Yeah I will check with Amazon directly at this point.

One thing to keep in mind when dealing with Chinese vendors is that they generally operate on the premise of buyer beware.. Not the US model of the customer is always right. Now this doesn't necessarily mean that they are out to screw you, it's just that it takes more of a process of negotiation. I'm not saying that I agree with it, but it is cultural and this is also what the seller is dealing with going back to his supplier /manufacturer who may be the ultimate bearer of any warranty. So I've found that the best way to to deal with them is with patience, politeness and a bit of humility while laying a little guilt at their feet for not honoring the warranty. When in Rome....
We decide to deal with them generally because of price, but in the end nothing is free and in the case of problems like this you need to understand who you are dealing with.
Anywho... Let us know how you make out.

Great points. Thanks. Yeah, I knew this whole thing was a risk. I used to like casinos, now I do stuff like this for thrills. Haha
