Bafang m510

[zorro77]

Hi everyone, I just bought a bafang M510 but I don't like the cap, I'm afraid that water and mud will get in. Is there a more precise and robust replacement cap? Link to buy it? Thank you

Hello Andy.

1200W electrical of DJI is remarkable. I wish Bafang will copy this HW gearing design - is best so far! Can be very reliable.
Difference is that Bafang can hold this peak for long. Bosh did overheat quite quick in a race (purely on Turbo) and did reduce power.

What a great article! A must read for all, even nerdy part for me.
Possible to find power curves also for the rest of motors?

Had one M510 with older firmware (with greater overshooting) and was peaking 820W. Bafang is measuring current quite precise, was comparing against smart BMS.
Unlucky, that latest Bafang controllers have almost no overshooting.

Hi Dado
DJI Avinox has an amazing motor, in older firmware version you could set more than 25 km/h, unfortunately not in newer version. Also, it's not clear how it's going to be with this motor to rechip to higher speeds-for now it can't. The question is reliability and repairs in case of failure too.
Rob has been hill testing DJI-Bosch-Pinion motors. The DJI is a world apart in performance and time achieved.
E-bike motor manufacturers are careful to withhold power and peak power data, so it is difficult to get data to compare motor power.
Even though I mostly ride off-road, a motor with a max of 25km/hr would put me off.
For the Seroxat with Innotrace controller, I now have a Lekkie Pacemaker throttle (it has a blue Led) and according to the bench tests, it modulates power very well and starts from a standstill just fine. There was no need to add resistors and tweak the voltage. I added a switch to it-throttle use only on critical places+different throttle settings with X1-Tool for 5+5 levels. The standard Bafang thumb throttle or twist throttle is unusable for me , so hopefully this throttle from Lekkie will be just right.

Hi everyone, I have two bikes with M510 motor
1st one is CRX10N.510.FC 1.0 with software CRX10NC3619i101021.1
2nd one is CRX10N.510.FC 2.0 with software MMG522C3619F802028.1

the problem is that the software CRX10NC3619i101021.1 don't have "Assistance %" option like the software MMG522C3619F802028.1 ---> look fotos
is the only solution to replace the driver with version fc2.0? or can I update the software?

Motor efectivity-comparison: It is often mentioned in user reviews that the Bafang motor M510 is less efficient than Bosch 4Gen or Shimano EP801 motors - that is, it takes more Wh from the battery to achieve the same power during a ride.
The attached video compares several of the most used motors by Extreme range test climbing (same rider, same conditions, same heart rate,...). The M510 motor was placed in this efectivity comparison behind the Bosch CX Race motor, but ahead of the Brose S Mag or Shimano EP801 motor. The best are Specialized Turbo and Rocky Mountain Dyname 4.0 and DJI Avinox.
Note: Not much details on the methodology, but I wonder how they made the calculation of the power consumed by the M510 motor, where the percentage of battery capacity on display is a very inaccurate. Unless you recharge again to full battery capacity with a charger with a wattmeter included.
