The parameters can be changed, except for one.

try using Besst pro 1.0.31 beta with phyton.

 

[LAnton]

With Best, you can change the diameter of the wheel and the speed is limited to 45 km/h. With the help of the wiring, you can change the limit to 60 km/h

There is no time to deal with the previous version of Best. I have removed the 25 km/h limit. The level of support can be changed. That's enough for me.

 

[LAnton]

Now we need to install it on the E10 frame to test the motor.

 

[LAnton]

Now it works, you can change the speed of 25 or 60 km/h.

Are these levers suitable for the M820?

I ordered this one :
Carbon Fiber Cranks 165 Q:8 Isis Standard (Black) for E-BIKE

That seems cool! But 180€ for cranks

How much do these levers weigh? Do we have the same levers for the M820 and M620 motor?

120 grams cost 180 euros.

this is the same as m510 if you change the speed to 25kmh you can change everything.Or you can try to set to 25 and than do the changes in besst pro .After that log in
besst and set speed to 45.

 

[TeoElFeo]

Has anybody tried riding the new motor already? If so, what are your thoughts? How does it compare to m500/m510?

 

[KaroKönig]

120 grams cost 180 euros.

Not quite, 1 gram costs 1 € , but the cranks fit perfectly, also the screws fit , only the Q factor is 12mm wider

 

[LAnton]

Why make a heavy steel bolt for the M820? An old bolt from the M600.

 

[LAnton]

How small it is, it is a motor for children.

u'll put to E10 frame to test?

Yes

Is this motor on the E10 frame?

I have a stupid question. I presume M820 motor kit comes without battery charger.
So what kind of charger will be needed for 43V/410Wh battery ?
Battery BT F014 states max voltage of 49VDC so charger have to be CCS up to 48V ?

Thanks

It should be a charger for 12s battery or 50,4v

There's just to 2 things to consider here. Charger voltage and charging port on the frame. So far most frames seem to come with a DC 5.5x2.1 female plug on the charging port. Also I can recommend you to get a universal DC lab supply where you can adjust voltage from 0-60v and current 0-5a. Very convenient, I use myself. Here's a good deal at the moment: € 50,22 53%OFF | Adjustable DC Power Supply 30V 10A 60V5A Lab Bench Power Supply Laboratory Stabilized Power Supply Voltage Regulator Switch 220V

That can be interesting at home to charge any batteries , but I would prefer a portable charger that I can carry easily if I need to charge elsewhere

 

[borysgo2]

I did some homework and found the bafang paper that in 43V system BMS is charging cells up to 4.1V so 4.1V *12 = 49.2Vmax. Found dedicated charger for about 60eur. Thanks
Lab psu is IMHO a very good idea.

 

[mike_kelly]

The Bafang kit comes with the charger.

 

[mike_kelly]

I should add for clarity that if you don't buy the kit with the bafang battery then you need to find a charger appropraite for battery that you do buy. Just be aware that every Lithium based battery requires a Battery Management System. Sometimes the "BMS" is internal to the battery but it can also be external. But because the batteries are actually made up of many small batteries or cells. They need to be balanced. That's part of what the BMS does. So you don't want to run a dumb (no bms) charger with a dumb (no bms) battery or you can cause a fire.

The motor is installed. I'm going to test this weekend. The weight of the bike is 18900g. Weight together with pedals and battery 1500g 360W 10Ah 36V.

u will be the first to test M820. Good luck and hope M820 will be as good as we all want. Follow u the result.
