Mate on his Focus Thron ( hasn't got the port for a range extender ) Gen4 motor is looking for a range extender which he can fit. His is the standard 625W battery but on some of our longer rides we are getting a bit of battery worries.
Has anyone got one working, any company make them, any...
Use Alibaba.com to contact Chilli Shen. She has been very good so far and fast delivery. If you use Alibaba you will get payment protection if she raises an invoice within Alibaba. DHL delivers within a few days of leaving China. Took about 3 weeks from order to arrive.
My M510 @ 52 volts and DPC245 display does not show the correct percentage. It shows 100% until the voltage gets down to 48volt battery levels. That’s not a bad thing as the motor will continue @ 100% power despite the battery being less than 35%.. The display shows around 40% when the battery...
How so, the pitch is exactly the same, the chain if setup correctly will not touch the nearby chain rings, where is the problem ? All chains are 1/2" pitch, all chains are 3/32" inner width, its just the overall pin length. I will take the extra 0.25mm of chain link thickness to try and stop any...
Tried all of the above and found going right back to 10spd lasts the best. If you go to 11spd you can use a 10spd chain ( ever so slightly thicker links ), doesn't change quite as slick when new but after a couple 100Km you cant tell the difference.
You only have to look at the likes of say Trek retail prices ( the dealers are not allowed to set prices ) and those of the Internet based suppliers of similar equiped bikes and you can see when times are tough and every dollar counts, the best value will always mop up the few sales that are...
I beg to differ Dado, I used AI just as a term that people would understand. No electric motor control is not in the realms of AI ( yet ) but basic machine learning algorythms are employed in any electric motor worthy of mass production.
Yes almost certainly Bafang will use an algorythm to work...
Guys, having just fitted a M510 with the Ver 3.0 display I have to say this is a very good package. I've run the M600 since 2020 and enjoyed it as a motor, but this is a step up again in being a very useable motor, particulalry in how the torque sensor seems to be much more of a priority rather...
I wonder what that is in regards to our battery packs ?
Could it be the BMS balancing out each cell to the common lowest voltage, by burning off energy through a resistor creating heat,( after the charging cycle has switched off ) after all our chargers are not “bottom up” complex chargers.
Most chargers will top out at 4.2V but with a bit of equalisation by the BMS after full charge current has stopped, will drop the volts back to around 4.15v, at which stage most home voltmeters are not precise enough to accurately show 4.1 or 4.2 over 12 series cells.
This is such an old argument that has been long discussed with its pros and cons. Its not just Bafang but Bosch and others all have some lag ( its almost impossible to prevent some inherent capacitance in the field windings and computer sensor delays ) often condoned by riders for climbing up...
