I’m really confused by Bafangs model numbers. They’re confusing even on their website. Sorting, and my apologies for any incorrect model references.

I'm curious about this info as well. I came to find out some info. It states there are 40 replies but I do not see any. What's up with that???

A link or brief explanation to direct us to where you are looking?

Did you figure it out? Do you have some specific questions?

Wow I missed this original thread and user's issue. And this one too. My excuse is I was in the Poconos on a business trip (really!)
@officerdare's problem *really* sounds like wonky settings inside the motor. I wonder what are those settings? Best would be screen shots of each of the three settings screens. Pretty confident we'll see a smoking gun in there.
52v battery is not any sort of issue. The only thing a 52v battery does is give some extra usable voltage. 14S packs have a peak of 58.8v and 13S packs are 54.6v. Increased speed is negligible and what little is there only lasts for a short time. The reason you go 52v is to stay in the usable voltage range of a 48v system for a longer period of time. As for problems caused by kaka battery manufacture... yeah sure. But that is a problem of cheapskate consumers, not the battery platform.
Absent a response from @officerdare, the version 2 in the linked follow-on article (page top) to the one below will yield pedal assist output in the 450w range on level 9. Six to eight amps continuous on flat ground, but that is a really big bike, so something a little less ginormous might eat fewer amps.
I have a mountain bike with the same settings that I need to ride tonight. Oddly enough I am checking the amp output of both bikes to make this specific comparison between the two.
That 450w is on a 52v battery and since the motor retains the 30a output, leaves full output/throttle available on request. It also gives a slow power rampup, and a near instant-off when you stop pedaling. Keeps just a skootch in case you want to use that split second of barely powered rotation to complete a gearshift.

(But Not For The Throttler) There is a follow-on to this article that tinkers with these settings a bit further. In August 2023 I published another update that passed along what I’m doing dif…

Why not open that battery case and check the assembly of the cells? Post a pic of your findings. Really like the looks of that MTB build btw.Wow I missed this original thread and user's issue. And this one too. My excuse is I was in the Poconos on a business trip (really!)

Cuz honestly it sounds nothing like a battery issue. I wouldn't want to be taking a battery apart unless I knew I had something to gain by it, and the user's description of his problem sounds entirely like motor settings.

Well, keep it in the dark then.

Now unobtanium, with recorded unfixable failure. Seems the made in USA is another of their. BS sales pitches. They misrepresented their battlers sources from day one.
