I think most Bafang engineers reading this would be considering your engine an outlier and not truly representative of the M600. Something is not right about your setup.
Why so, the existing M600 does all the above in power terms if you run it on 52 volts ( no modifications needed ) just its 0.5kgs heavier. This is just an engine advancement rather than impressive in my view.
Just run a 52 volt battery and have one less pint the night before and save yourself a...
Meet the new, lightweight carbon bike with the m820 motor. I will receive the frame and motor at the end of January. According to my calculations, the weight of the new bike will be from 16500-18000 gr. Depending on the level of components.
Yup you will need 3P at least, check this thread out.

I'm not sure about the Giants battery and letting the BMS go cold other than reading a long time ago a thread where the poster had not done so and the...
Mine seems to want to just spin at a set rpm, I just set the gearing accordingly. The irritating part is about 20m up the path you want to start riding again but you are then in too tall a gear to get going.
Dado most of what the USA guy is saying has yet to be proven ( I'm not sure but he is saying his display max's out at 750W, that may not mean that the motor doesn't produce more ). He has problems understanding that the M600 needs to have a higher cadence than the Brose motor he is comparing it...
Efficiency of the M600 & M510 will be almost identical, the M510 to be stingier will have to be slower ( less Watts ) or you will have to man up and make up the difference with rider pedal power.
Won’t go or only very slowly, the Samsung E50 cells are only good for about 5amps max @ max volts, the voltage sag will trigger the BMS.
The Samsung 40T will be fine up to about 500W’s but have less capacity.
The other concern is keeping the BMS alive whilst transplanting the cells, wasn’t...
Do be aware that the cold temperatures will be affecting the total output, particularly as the 4P setup will be now not putting much strain on each cell ( less heat ).
In response to Patdam, yes its better but rather than a flat plate of carbon which is highly conductive, try fitting 2mm ABS...
More like "many weeks" and many charges.
You need to use and charge this battery at least 20 times before getting wound up by a very small amount of W'hs that potentially you will never ever need. Remember that the 0.03V across 13 cells that you are withering about is the top float charge which...
Shhhssh dont openly ask the question, but can the motor be err given just a wee bit of top end range. You cannot believe how much nicer the bikes are when you are not nudging into the speed limiter the whole time. Particularly the lightweights seem to be most afflicted on trail rides.
Its...
Chris, I don't think anybody has accused you of lying, just this is an internet forum where not all can be taken as gospel. We need a bit more proof before we can say yes VMG Chris is the biz, nothing more than that.
If you have indeed a close relationship with Bafang why not put a bit of...
What makes you say that ? Our doubts are that Bafang have created a problem in that newer versions do not solve the existing problems to date. Does your version, we don't know yet as Bafang haven't released it.
Yup the cells will recover pretty quickly with a surface charge that can fool you. The cells I’m using should be fine as I was only pulling very low amps when the battery shut down and according to their test specifications, well within limits.
Out of interest next time I have a lowish battery...
Correct in theory and I had expected that as well, but the motor shut down at 42 volts. That means the motor has auto detected a 52 volt battery and shut down accordingly.
Bit of a pain as I ended up riding 8 km with nearly 100m rise on a dead motor. The only upside was that it is possible to...
Something to consider. I finally for the first time ran my battery fully out, as in the bike turned off due to a low battery. My M600 is Ver 46.7 on supposedly 48 volts. I have run it on 52 volts from new without problem and assumed due to the higher voltage, that it would be the BMS that would...
