    Battery charger confusion

    Thanks for all replies. I am suspicious that this is a 48V lead acid battery charger that was re-purposed for lithium ion, but not really spec'ed for the task.

    Battery charger confusion

    So I have a 13s4p 48V lithium ion battery with MH1 cells. The battery charger supplied with it has specs of 59V 1.8A output. My battery reads 53.7 V at full charge. The charger when tested has output of 56.5 V. Something doesnt seem right? Thoughts? Thanks.

    Steel dropout spread from over tightening

    Awesome that's good to know. Hopefully I have now limited the damage to these forks and they will be ok. Did you do the welding yourself?

    Steel dropout spread from over tightening

    Awesome thanks! I think if I would have retightened the axel nuts instead of taking it all down I would have further spread and deformed it, and then it would have loosened again, and eventually it would be beyond saving. I just hope I haven't gotten to that point yet!

    Steel dropout spread from over tightening

    Hi everyone. I'm pretty new to this and a bit disappointed this morning. I installed a 1000W hubmotor on my front steel fork of my fatbike a couple weeks ago, and thought I'd done a good job. The spacing was tight, so I wasn't able to put any washers between the inside of the dropout and...

    What exactly do torque washers do...

    All things being equal then - with the torque arm bolted onto the fender eyelet.. Is there any functional difference between welding the two plates together vs just having a really tight bolt holding the plates together. It doesn't change the length of the lever in any way...

    What exactly do torque washers do...

    So do you feel welding the two pieces of the torque arm together would have no additional benefit over bolting them?

    What exactly do torque washers do...

    Agreed! I live a few blocks from Grin (ebikes.ca), and there torque arm kits have the c-washers that clear the lawyers lips. So I have things snugged down about as well as I can. The thread about the testing is very good.

    What exactly do torque washers do...

    Fair enough! What I visualize in my head (and may not actually be real), is that if I get a fork spinout, and then my axel drops out I could have a pretty major crash. I'd rather NOT crash and if my axel doesn't fall out with a spinout (ie by having a welded torque bar), then I might destroy...

    What exactly do torque washers do...

    Awesome thanks. My 'BS meter' was going off when I saw the torque washers included in my CNE kit (1000W, 48V, steel fat bike forks). I used two torque arms from Grin instead (the V2 version). I'm still worried actually as the torque arms have a bolt connecting the two pieces... I think I'm...

    What exactly do torque washers do...

    I think your confusing friction/wedge washers (Nord-Locks) with torque washers (tabbed washers). In particular the cheaper tabbed washers with a minimal fold which I don't see providing any amount of safety!

    What exactly do torque washers do...

    Hi everyone, I have a pretty basic question here.. I've tried to search for answer but its never really clear... How exactly do torque washers make an ebike safer. I can understand how a torque arm works, because it is bolted or welded to part of your fork. But a torque washer just has a...

    Motor not working this morning

    Problem has been completely solved with fully seating this connection (thank goodness!).

    Motor not working this morning

    Yes I can see why, you really do have to push quite firmly to bottom it out.

    Motor not working this morning

    Oh wow! This is embarassing. Your absolutely right. I never got that connector properly engaged. What I 'thought' was connected, was actually not fully plugged in. It took a pretty good push together, and it bottomed out about 1/4 inch deeper. Now it is very secure. I think we can call this...

    Motor not working this morning

    Awesome ! Great idea. Just follow up. Today I was riding home, went around a corner and hit the throttle. The motor started sputtering, and had no forward power. Thought the battery was dead, but it was still at 49 V (48V 13S4P lithium battery). I pulled the 9 pin connector (discovered...

    Motor not working this morning

    Can I just ask then.. If I ever have to troubleshoot the phase or hall wires, what can I do with this type of 9 pin connector??

    Motor not working this morning

    Yep thats the connection! I'm starting to think that my cable ties might have pulled the connector apart slightly, but enough to shut down the motor. Thanks for reassuring words that these are well made, because its kind of leap of faith when you buy these things.. I did a pretty good hill ride...

    Yes the submit wasn't working. Apologizes for multiple posts!

    Motor not working this morning

    I really hope this is the problem as the motor is brand new and I don't want to start taking it apart. I think I'd rather it just breaks if that's the case and warranty it...

    Motor not working this morning

    Awesome thanks for reply. Yes probably something like this going on. Would all of these issues require taking the hub motor apart.. Sounds quite intimidating as I don't have a huge amount of experience with this sort of thing!

    Motor not working this morning

    Thanks for replying. I feel like there was a very slight shudder but might have not been. I went off the throttle quickly when no response as I think I could burn my MOSFETS that way? I have NOT attached my ebrake wires. I am not using the PAS. The only things hooked to my controller are...
