I do not know the new ANT BMS versions, but the first thing i would try is to raise the discharge ocp time to 60 seconds then it takes much longer to Trip the bms. Have you checked what is the real reason for the bms to cut the power? Does it have an error log?

I have to use an old phone with an old app for my 721800 which is also not working with the new BLE.

You can't solve this. If your controller can work wirh the new BLE module then buy a new one. This seems at the moment the only fix.

Offset angle has nothing to do with the hall angle 120. The controller does self learns the offset. No need to change manually.

Fardriver changed the BLE module, and for the newer controller there can be bought a new module. But some of the older Controllers do not work with the new BLE. My 721800 does not connect with the new BLE from my 72680. If you want to change the values you could try an older software version. I...

The value is the same as for the R4850 and then the R4875 produces the same current. When you add the connection to get 4kw from the r4875, then it makes 33% more current with the same settings. But I do not know if there is a different value for 120V input, as I am on 230V mains. I have 20 as...

Where you able to do an Auto-learn. During this the controller learns the throttle settings. If your throttle has lower or higher settings the controller will show a throttle error and will not spin the motor.

Mine beeps when brake or sidestand is activated and I twist the throttle.

Pictures of the 30/90A version I killed one , when I changed my charge plug from 2 poles to 4 poles. Made a perfect short circuit, the contacts in the plug got vaporized. The 6000A short circuit current was too much for the mosfets. The installed A123 Lifepo Pouch battery has 2V sag at 500A.

No need to worry about 1 or 2 kg , I have installed 120mm² copper bus bars 3mmx40mm. Only a little bit oversized. 😉 My battery can do 800A continous. The other option I had was 0.8x40mm which was mechanicaly to weak for me.

I would ask the seller for the wiring of the 21S configuratiuon. I have seen already three different BMS wire setups from different BMS manufacturers. One as Dui has shown in post #157. One where you have to connect all unnused wires to the last B+ One where all the unused wires are not...

The Fardriver ND72680 is a good controller. Cheap an powerful. Twice the power like a Sabvoton SVMC72150 and a lot smaller. I used it for a year before I upgraded to the ND721800. Before I had the SVMC72150 installed for two years. I had set the 72680 to 300bA and 600pA. with my 5kW QS260...

0-100kph in 6.5seconds. My scooter is 190kg heavy without me, I´m adding another 90kg. It would be faster if the BMS could handle more than 400A , but I fried one while testing with constant 500A after 13 seconds. It actually reaches 0.8g peak acceleration between the first and the second...

If you are shure that you used the right code then a USB-CAN converter will not change anything. Probably your psu has a different firmware or is defectiv as you already wrote.

Autotune detects (visible) only phase angle and throttle min max values. There is no change in p i d parameters or motor body value (AN)
