    Bafang M820 Firmware thread

    Thanks for explaining, that table seems good. But my point is the i-version(13S 13A), does not follow that table. Now at fully charged it shows 86%. On my brief test on f-version it was at 100% when fully charged, so based on that the f-version is according to the table but the i-version is not.

    Bafang M820 Firmware thread

    So tried the f1 version briefly in my yard. Battery was full and it showed 100% on the display. Installed the i1 version and went for a proper ride. Battery still basically full(99% on bms) but display showing 84%. After the ride it was showing 31%, same time bms showing 51%. Otherwise it was...

    Bafang M820 Firmware thread

    I have been on faketaxi f1 for some time and I like it a lot. Power delivery is smooth, battery performance is good. When I drain the battery completely I never go below 5%. Usually at around 10% it starts switching off. I guess it is the bms cutting out, I might have one or several cell going...

    M820 Bafang - LIGHTCARBON LCE930 Frame (lightweight)

    So i had a new issue. I have been planning to change bearings in the linkage. Not because of bad bearings, only because it is already ridden over 5000 km on stock bearings. Old ones are still smooth. Yesterday I noticed big play on the left side chainstay/seatstay bearing, like 2-3 mm. So...

    M820 Bafang - LIGHTCARBON LCE930 Frame (lightweight)

    I have emptied my battery fully several times and used it with different firmware and I still have same problem. It has been present already for over a year.

    M820 Bafang - LIGHTCARBON LCE930 Frame (lightweight)

    I have this same issue. No idea what the reason is, but luckily I have smart bms so I can do it from phone. First I did not like it, but now when I got used to it, it is like a soft lock for the bike. No way any "normal" person could figure this out. If you don't have smart bms, maybe you can...

    Bafang M820 and CEF55 frameset

    "official thread" build thread Similar bike Just search, there is loads of info here.

    Poor man's CEF55 build for long trips with 1kWh battery.

    This is interesting! I have the f1 firmware, Jbd bms. At 4% it shut off by itself. I was thinking it might a single, or a few, cells going too low. After maybe 30 seconds it started again. But only for maybe 10 minutes more of easy riding.

    Bafang M820 Firmware thread

    A 13A firmware (like the standard 43V bafang firmware) is close to 700W using the 48V battery.

    Bafang M820 Firmware thread

    So FAKETAXI20260210f1 tried and tested. Feels good, power delivery is smooth. I don't know if I were imagining, but it felt like maybe a tiny bit more overrun than the 20260202f1. Not much in any way, but the earlier version had close to zero. This felt good, since it is predictable. I was...

    LCE930 - Rearshock Bottom Bolt m8 is a bit lose

    This won’t work, the bolt is 8mm but the nut is 10mm OD. If you use the existing nut, you can put any M8 bolt with partly unthreaded part(~25mm). The original also has a cone shaped part to account for, so if you add that and a spacer it needs to be about 30mm unthreaded. The original bolt is...

    Bafang M820 Firmware thread

    Well I have been running the 43V version with 13S battery for a year now, around 2000 km, so it seems to hold up well. Still if the only difference is maximum power I probably don’t need it. Even if power is always nice to have, I did it to get more out of the battery. I have two batteries...

    Bafang M820 Firmware thread

    One question on the different voltage firmwares. 11S is using 36V firmware base, but 13S is using 48V firmware. Since it can handle one more cell in serial connection shouldn't the 13S be using 43V firmware base? And 14S 48V and so on..

    Bafang M820 Firmware thread

    I have not tried all, but the road version for 43V at least had a loong overrun. But the worst about it was that it was not consistant, ranging from maybe 0,5-2 seconds. It made technical riding extremly difficult.
