Re: 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 not the ...

Re: 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 bik...

Re: 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 standard speci...

Re: 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?

Re: 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 was 100%...

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

The battery likely has mismatched cells from the factory, which are the reason it became so disbalanced in the first place. This is unfortunately very typical for cheap batteries. The disbalance is probably so intense that it would take multiple days to balance the battery. *if* the balancer works....

Re: Intro guide to TSDZ2 & BBS02

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! Are you joking? TSDZ2 provides a great value for the money!! I have 4 eb...
