    mxus xf15 gear hub motor teardown

    Got another same 22A (third one!) and this one also gives an output of 900W+ SO I COME TO THE CONCLUSION that there was something wrong(a good wrong for me!) with my first controller that gave the 1250w+ output !

    mxus xf15 gear hub motor teardown

    Got my hand on 2 of these 22A intergrated to the battery base controllers and tried both of them and both gave me only a little over 900w max output on a fully charged battery ,so i guess probably my first controller that gave me 1200w+ output had some kind of flaw(good flaw for me!)and was...

    mxus xf15 gear hub motor teardown

    So i am having an issue with my controller (i think!) the display started to get stuck at 600-660w and the motor stoped working,i had to close and open again the screen so it could work again ,the motor would not go above that 600-700w and after shut down again and showed me an error "Motor...

    Trying to increase my batteries longevity but did i actually destroy it doing so?

    And i had 2 of these,to have both BMS'S not working properly what are the odds? So i will change the BMS again once the new one arives and see if all cells will balance below 4,20v(after 100+ full cycles is it normall for batteries to still reach 4,20v?)if that dont work then can i still ride my...

    Trying to increase my batteries longevity but did i actually destroy it doing so?

    Ok so somebody correct me if i am wrong but do'nt all 18650s or most have a Standard specifications of 4.20v, +- .05v if so and to say that my BMS dose'nt work then is'nt it normall that my batteries reached 4,23-4,24V (even if they had reached 4,25v it would still be in the batteries...

    Trying to increase my batteries longevity but did i actually destroy it doing so?

    This was measured half hour after charging and yes i took the bike out until the battery droped from 54,1 54,2 down to 52,0v. And why may i ask is the battery a liability,all BMS"s have Over-charge protect voltage at : 4.25V so the cells wont damage, am i wrong?

    Trying to increase my batteries longevity but did i actually destroy it doing so?

    I am starting to beleive that maybe my problem is not bad cell or cells but more a matter of a very unbalanced battery pack! As i wrote in my post once a month i charged to 100% but did i actually do so? I charged until the green light on the charger had turned green ,that is what i thought...

    Trying to increase my batteries longevity but did i actually destroy it doing so?

    I dont think that the battery had mismatched cells from the factory because after a month of use i took it to this battery guy and he mesured the Voltage at each of the 13s with battery nearly fully charged and all 13s where from 41,5v up to 41,7v max,the battery guy today also told me that up...

    mxus xf15 gear hub motor teardown

    It is the controller ,it says 22 +1ah so when the battery was fully charged 54,6v(now after a year and about 120 full charges it only charges up to 54,0v,is this normall?)so actually i got over 1200w output(about 1250w !)and even now i get a little over 1200W but that is i said just when...

    Intro guide to TSDZ2 & BBS02 (updated 2021)

    Sorry my friend but the person that wrote this thread says : Be aware that without thorough maintenance the motor has a limited lifespan due to some weak mechanical spots, and :My unit's never lasted more than a year of almost daily but careful use!!!! And when i also read about faling cranks ...

    Intro guide to TSDZ2 & BBS02 (updated 2021)

    So people should stop buying TSDZ2s AND PROBABLY THEN THEY MAKE A TSDZ2 -2 with cadence up to 120 RPM,stronger torque arm ,metal gear and better heat dissipation(some fins on the outer shell maybe!). And then maybe we buy one!
