yes installed without any problem, but cutting still occurring, may be little less intrusive than 3.02 but not great differency, usable but not plaisant. My controler hard is CRX10N.510.FC1.0

That is unbelievable, that Baffang is still selling M510 with buggy firmware. What a stupid decision from managers there. They wont make a good reputation with this motor then. So it really looks that first working firmware will be here next year. :(

Patdam, and when did u purchase your motor? U must have third revision. It did come with 3.5, right?

Anyway do u see peaks over 800W with 3.5? Wondering if they left there current "overshooting". Firmware stating 14A max, but it is rather like 16.5A. When I was checking current measurement accuracy, it was almost identical with current measurement on my BMS.

Not received in 3.5. i received it in july/august (ordered in april) with 3.2. but only ride in end of october, i have upload the 3.5 after first exit
Too many bad eyes to see the A or W in DPC 241, but when it to don't cut, the powerful increasing is lot off better for me. we feel that torque sensor is more sensitive and acting more than those of M500/600, is ir the problem ? it's also cut the motor when he feel less crank arms torque ? i don't think so because it cut also when i climb sometime

Interesting, that you got third revision in july/august.

When cutting off in climbs that is wrong. So still the torque sensing issue. :(
What I dont like on M600 is wrong torque sensor calibration - you do not need even push on pedals and M600 on PASS 1 is putting lot of power (it is going 32kmh on straight with almost no pushing on pedals).

Dont understand why they can not add some coefficient for a torque sensor to every PASS. Then user would be able to setup pedalling strength.

I finally found the time to upgrade the M510. I changed the acceleration settings to a minimum. The power has been reduced by 50%. I want to try if I like to ride the M820.

Who of you has experience with running m510 on 52v? Did you feel a noticeable increase in performance/torque?

I am getting a custom battery made and it's 52v 20ah because that seems like it's the maximum this frame can fit. Sometimes I feel bafang is quite underpowered especially when the rpm drops. I am wondering if running it at 52v will give me some noticeable increase in oomph?

Also most of my levels are tuned down for the sake of reducing power consumption. My current fw has an lvc of 44v which is basically the lvc for 52v so I am loosing around 15% capacity. I hope the 52v will also solve that issue

Hmm…the firmware I‘m using is

CRX10NC4814i101003-1-cs-28-2230-boot3-0-20220517161110-48v-M510.bin


cutting off at appr. 41 V. The firmware @Dado posted recently reduces max Amp only below 10% SoC, so I assume LVC is also at 41V. Can You confirm @Dado?

May be several revision on network ? for me the rev 1010.3.1-cs still have the motor cutts, mostly in pas1. Troublesome and physically exhausting

I don’t observe that with my bike. I strictly follow the start procedure (no load on pedal for min. 30s after start) and almost never use PAS 1…

PAS 1 would means level 1 on 5, no ? i haven't seen that is a conditions to use the M510

For my practice it is the mostly level used. +-70% level 1, +- 20% level 2 and +-10%level 3. yesterday i ride 1200 m D+ in 27 km and i finisht with 41% of battery. I 'm not interested to climb more quickly and i want to be able to climb +-1500 m serenly (without risqs of battery fully empty) , i appreciate to admire the landscape when i climb in moutain. the fun is at downhill. i will change the motor and wait a firmware where i can use the level 1

Yes, PAS = what You call Level, I also use setting with 5 Levels. I‘ll check if I observe the same cutout behavior using Level 1 on my next ride!

My M600 will do something similar in its lowest setting. If the bike overuns speed wise the peddling speed at higher cadences ( as in there's no or almost tiny amounts of torque from the peddles ) the motor can get into a bit of quandry of does it supply power or not. It is particularly noticeable if the terrain has very short undulations where the bike naturally raises and lowers its speed and the motor cannot get into a sort of rythym with the undulations.

On the higher settings there's enough power to speed the bike up enough ( because of the over run ) that the next no power point is definitive, desite the terrain.

It's something like that i feels it on flat road, not really a problem, i switch to PAS 0, the assistance is not necessary. But when it occur in cilmb and you strength on crankarms, it's seem like the torque sensor or speed sensor or may be software calculation gets lost. I have tried to increase RPM or torque on arms, it doesn't change anything. it is very tiresome and annoying. when i'm sto irritaded i switch to upper PAS, but i don't appréciate to have more motor help when i wouldn't want it.
It's seem like the M510 is designated to function under lower human effort than motor. But the strange thing it's sometime (few) it seem well functioning, i'm asked myself if it's because i don't turn crank arms perfectely "round" ? In any case i never had this problem with the other motors used at so far.

Are you sure your magnet and speed sensor on the rear are not too close. We were getting a similar random odd speed related problem on the TSDZ2 which we solved by widening the distance between sensor and magnet way outside of the manufacturers spec. Try turning the magnet around on the spoke so the magnet is on the inside, you have nothing to lose.

Sure of nothing. But i have take care to the speedometer and it's staying stable. I have tried with 2 magnet (one more shorter than original. It is also clearly 1 time by each turn pedal not aleatory, alike the previous problem on M500 (solved for me with unmagnet sensor fixation screw)

If you have already widened the gap, have you now gone too wide for the M510, Bafang may have altered the firmware if the M500 had a problem.

i have questions for those who are satisfied by the rev 1010-3.1-CS.

do you use wiring with throttle ?

do you have battery whitthout on/off switch linked directly to battery (BMS) ? do you use another battery than those provided by dengfu or bafang ?


before removing my motor i want to be sure that my problem of cut really come from the motor

I have unplug my battery (permanentely plug to the motor) and i have take care to wait (5 mn) before using bike. cuts don't more appear on flat ground, but still occur sometime on climb, mostly in PAS1

My opinion is that software calculation is getting lost when you use low values (speed/arms torque/PAS)

I explain:
I can climb during several minutes (ten) whithout cut, on 20%, at 8 km/h, on PAS2 with strong torque on crankarms. But if speed reduce to 6 km/h or/and if i reduce stress on crankarms. When i return in previous condition, i have cuts and it's take several time to return in normal state (if i don't change parameters). And i can't if i try to compensate the cuts (by increase stress on crankarms for exemple).

Pity, because when it work correctly the motor is very funny, lot of more efficient than M500 to hard climb. i can climb in PAS2 where i have difficult in PAS3 with the M500. I can't imagine what they do those who use PAS5 ? how many time (lot of consumtion i suppose) ?
But in "normal climb" (5/13 %) where i like to ride at 5/6 km/h to admire the landscape and speak with my friends who haven't AE,. where i use PAS1, the cuts make you want to break this motor

Does it work? Is it possible to configure all modes? How much is it?

Hello Lanton. Of course it does work. ;)

What u mean configure all modes? Do you mean all passes? Now same as besst pro, you setup 5 passes and device will calculate the middle passes for 9 pass ( average value - you see the middle passes as a small dots on a graph).
And cost 170e (with m510 support) plus 10e shipping in EU. Check the page K1 eBikes & Smart IoT Gadgets is creating Ebike electronics, high-end and powerful ebikes | Patreon

Will start on a waterproof version soon, which is tricky and looks like I will sink few displays and microcomputers during submerge testing. ;) . But now need some rest, it was lot of sleeples nights to reverse engineering can protocol, make graphics and learn to code nextion display (u can imagine that chinese script language, but is good that HMI can be coded exclusivelly in this display and works seamlesly)

Anyway somebody knows how bafang designed 10 PASS levels? If added just extra tenth pass and some mapping again? Also devided to eco and sport, not sure if theres something special apart of defining power and acceleration (which does not work yet on M510) on each pass.

A good way. The future belongs to bafang. I understand that bafang is not perfect, but it makes good and inexpensive motors. Why don't you make an application to work on a smartphone using bluetooth protocol? Everyone has a lot of old smartphones, they can be used as screens. The M820 has no screen, only buttons and blutooth, I think it's convenient.

Hi @patdam I dont use throttle. I tried PAS 1 yesterday at low speed / pedal force. No cutouts.

Thank for the return thaeber. i have tried whitout throttle, no differency. I have chage the plate (32 to 34) and the crankarms (160 to 170). I don't now if really amelioration or if i manage better the motor ? cuts still occur, but less intrusive. only on low torque on arms, never in hard uphill. I can deal with it. Very funny this motor. The strange thing is that now i can't update the 3.5 rev (previous done), systematically "ERR 30" ?
