    Sabvoton 72150 hall settings

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

    Nanjing far driver controllers

    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...

    Rectifier Huawei R4850G2 48V 42~58V 3000w

    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...

    My Fardriver error beeps looooong when I twiist my throttle and beeps a long beep until I release the throttle.

    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.

    New mini 7S-14S 30A BMS with switch, temp, BT, UART

    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.

    Yamaha YZ450F

    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.

    Battery build & Controller Upgrade

    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...

    Battery build & Controller Upgrade

    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...

    I hope to find a harness description for a Fardriver 721800. I’ve lost what goes where, :(

    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...

    Emerson/Vertiv R48-series CAN programming?

    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)

    Emerson/Vertiv R48-series CAN programming?

    I would just try to send only one offline message to one psu wuth an USB-CAN converter and see what happens. I have programmed about 150 rectifiers n the last year. I had one that was 1V off and 1 that did not accept a input current limit. All the others worked like they should. For the megmeet...

    Emerson/Vertiv R48-series CAN programming?

    There must be something wrong in the Code or the voltage values , if they are not set permanently the revert back to 53V. I'm not shure if they can be hooked together to one can if the output is connectted in series. The Huawei and the Megmeet work in parallel and in series on one can bus. I'm...

    Masini Extremo build scooter with >30kw

    I'm still working on the can code for the delta 48V 3000W rectifier (the one on the left) which is only a little longer thsn the Vertiv R48-2000e3. The Delta is 1.3kg at 3050W. The Vertiv .is 1.13kg and the Eltek on the right is 0.85kg. Two Delta in series with a 30V 3.2kw supply will make a 5kg...

    Masini Extremo build scooter with >30kw

    New small charging setup 2x Flatpack S 1800W in series. 73x83x260mm or 41.5x146x260mm . 2kg max 37,5A The Flatpacks are smaller, lighter and more quiet than my previous Vertiv R48-2000E3 setup. The Vertiv turn up their fans to nearly full speed under 48V even without load. I still have to test...

    I hope to find a harness description for a Fardriver 721800. I’ve lost what goes where, :(

    Sorry, I have already installed my 721800 and have no easy possibility to have a look at it. Running it with 400A battery current and 1400A phase current with the new QS273 72V10kw 60h motor it feels like driving a mid size motorcycle. Here is a picture from the 96850 plug, but I'm not shure ift...

    Rectifier Huawei R4850G2 48V 42~58V 3000w

    Depends on your plug. probably you have a different version. I had four versions plugs until today and all worked with the black wire from start. The plug next to it is CAN. The fourth not on my picture has 3 more wire pairs on the right side. CANID HEX 10 80 80 FE broadcast to all...

    Battery build & Controller Upgrade

    If you want something smaller than the Anderson and do not want to plug it often , just take two QS10 plugs and take one of them for plus and the other for minus. The qs 10 can handle awg4 The wire ratings are all for continious operation 1 hour or more. You can not draw 400A for an hour from...

    Nanjing Fardriver stuck setting

    Yes had the same thing with my 721800 , could only change the first two values in the ratios of speed with the new app. I change values with the old ap 1.5.5. and save them with the new ap 2.4.9 or now with 2.5.0. , because the old app does not save the values. Probably this has also something...

    Ninja 250 "Clone" Made in China

    My new QS72V10000W motor has the same problem, the two older ones did not had this issue. Nice idea how you solved this. Don´t know if I have enough experience for your solution, I will try it with the angle grinder first.

    Converting Polaris Ranger - Question on controller & Voltage

    You can just try it with a normal DC power supply,. You can also spin the motor with a power supply, as long as you do not turn on regen.

    Converting Polaris Ranger - Question on controller & Voltage

    If you have double the voltage you will have only half the current for your desired power level. 48x300=96x150 If you already have the 304Ah cells, I would start with them. Estimated power will be half of what others get with the QS180 and you will also get only 3/4 to half of their rpm. 8C...
