    DIY BAFANG builds with torque sensor? based on 2024 workbook

    While I agree with what you are saying I couldn't find anything that could confirm it would be the same, just a few different people mentioning it had to use their smile battery. "JohnnyNerdOut" on youtube had mentioned he can't use any battery with his m625, but has also stated he should be...

    DIY BAFANG builds with torque sensor? based on 2024 workbook

    They have been out there for a little bit, high voltage did a video on the m635 but key things are its canbus 🤢 and requires their "smile" batteries 🤮.

    Nucular electronics - complete kit for ev!

    This is great news, any estimation on when we can order, I would like to try one out with my bbshd. I'm also curious will the new revision be the same spec's as before or will it be higher, I'm after 150 phase amps so the current 6f would be a little lower then I would like

    Bafang G510/M620 (Bafang Ultra) thread

    UART ultra is fine, I think most will highly prefer it over the canbus, which can be reprogrammed but requires a expensive bafang tool vs a cheap connector and free pc software. You might not need to reprogram but it highly depends on what you want from the motor, programming can change the...

    Bafang Ultrawithout hall sensors

    Hey I guess the pinout I gave you didn't work? I don't think the canbus had a revision change so I'm surprised to hear it didn't (although the 750w and 1000w are different so just to confirm you do have a 1000w right?). I do want to make sure the original controller still works with the motor...

    How To, 50A BBSHD Controller Mod

    I wouldn't say just for overvolting, more so over amping. Running higher voltage like 72v means you need less amps for the same wattage so less heat which is what causes the peanut butter failure. I would say the shunt mod controllers are the most likely to experience it, lower voltage with...

    Hey all, looking for a bafang m620/g510 hall sensor assembly pcb

    This is the pinout for the Canbus board, straight from the source of that video, I know people have made it work with canbus before. If it doesn't work you might need to recalibrate the board with the original controller for the magnet first not sure. I recommend you join the "High Voltage"...

    Hey all, looking for a bafang m620/g510 hall sensor assembly pcb

    You might not need hall sensors as it was discovered you can tap into the lower board to get hall outputs

    How To, 50A BBSHD Controller Mod

    When you unplug the motor from the battery hold down the power on your display, it will turn on for a second or two and then back off, should be drained enough after.

    BBS-FW: Open Source Firmware for BBSHD/BBS02 Controller

    So I would agree you likely have the newer sensor due to the huge discrepancy of displayed temps vs case exterior temps. Your look pretty close to mine, case temp do seem to be slightly higher but I do run heatsinks and thermal pasted stator so that's expected. You also are running about half...

    BBS-FW: Open Source Firmware for BBSHD/BBS02 Controller

    If it's the newer sensor I wouldn't worry at all, I hit 100C all the time and the guy who designed and tuned the Lunacycle ludi v2 controller (what I run) told me he tested it with a 140C limit and had no issues. I've found the highest my exterior temps get with 100C limit is 45C. Before I got...

    BBS-FW: Open Source Firmware for BBSHD/BBS02 Controller

    Hard to say for sure, as it depends on your tolerance to temperature. Another way to guess is the age if your bbshd, from what I've read it was somewhere around 2020-2021 they started moving the placement of the probe and even then switched from a 10k ntc to 1k ptc, the older yours is the more...

    BBS-FW: Open Source Firmware for BBSHD/BBS02 Controller

    Motor temps depends on what sensor your bbshd has, the bbshd can have either a sensor just placed on the hall sensor pcb that effectively reads the air temp inside the motor or a sensor placed on the motor laminations which will give a more accurate reading. To figure out what one you have...

    Downhill or Enduro bike for my new build?

    Didn't realize you were in Spain, I'm over in USA and somewhere that mtb isn't big so trying to find a good deal on a full suspension frame isn't easy. Only real place to look is pinkbike and something with a good amount of travel and room ends up being almost exactly what the E55 would cost...

    Downhill or Enduro bike for my new build?

    Figured I would ask, have you considered a m620 frame like the dengfu E55? Full suspension and plenty of space for large battery, saw a post on FB of a custom 1700wh hard pack in one. Only bad thing though is that aftermarket for the m620 is.... *crickets* now that innotrace is withoutatrace...

    BBS-FW: Open Source Firmware for BBSHD/BBS02 Controller

    I've seen threads online about using zip ties on the cassette to a wheel spoke to do a kind of diy solid hub, but the key is that you use only one really small zip tie so it can break off if in a high stress situation mitigating any damage. I thought about trying it but never got around to as my...

    BBSHD permanently stops assisting

    That's weird I haven't heard anyone experiencing that issue before. Are you using windows 11 (not sure if 11 is supported) and do you have a antivirus program? Might be worth making sure to have that turned off and maybe try on a different (windows 10?) pc? Hope it gets figured out for you

    BBSHD permanently stops assisting

    The firmware on your new controller likely expects a newer temp sensor and is confused and misreading it as way too high. I assume this because you mentioned you have had your bbshd for a while and I know bafang switched from a 1k ptc to 10k ntc a bit back (don't quote me on those I remember for...

    BBS-FW: Open Source Firmware for BBSHD/BBS02 Controller

    Interesting how yours seems to stick very close if not equal but mine I've observed to have a rather large difference at times. You've convinced me to reattach my temp sensor to the exterior of the stator to test more on hot it it gets vs the inside temp. I really don't want to have to open the...

    BBS-FW: Open Source Firmware for BBSHD/BBS02 Controller

    Thank you for the huge amount of detailed information! Yes haha I agree 40°C is definitely hot, I've only ridden the ebike twice in the morning in 2 months because of it haha. Maybe so, it's not completely horrible until you hit a red light and then you really start to feel it. That's probably...

    History of the Bafang BBSHD Over the Years

    One step forward, 3 steps back if you even consider this a bbshd. I'm sure companies like High Voltage will come out with offerings to fix the locked down software and battery limitation, but then we are back to a bbshd with nothing really notable changed except the torque sensor, and a worse...

    BBS-FW: Open Source Firmware for BBSHD/BBS02 Controller

    Curious what warm is for you in degrees. Sitting at 64km/h for 7km without overheating / throttling seems crazy to me, when I ran a 45a shunt mod just accelerating for say 25km/h with the motor almost at ambient temps to 64km/h (which was the top speed I could get) I would be dangerously close...
