Hi, We bought this Fardriver controller, which says it has FOC for PMSM, but it doesn't work. I'm not sure which the encoder wire is.. is it the purple 'digital one'? I'm even thinking this might be for regular DC motor with 3 halls but I'm not sure of the model numbers. Anyone know this well...

Hi, I got this unit YS72660 by 'Shanghai Yuanshen Conversion Tech Co Ltd'. Didn't find anything online about it. Hoping someone here has seen a schema diagram of the signal wires and if it can be accessed to read configuration parameters. Appreciate any help. Thanks.

Thanks for the reply :) I wrote to them and the good thing is that they replied the next day. The bad thing is that they wrote: "the default version BMS don't have CAN communication and RS485 . . CAN communication and RS485 need to custom made before placing order". On their advert it does say...

Hi, I only found a low res image of the ANT BMS communication pins (attached). Does someone have a better image to share so I can be clear about the specification of each? I couldn't find anything on Google. Thanks, LG.

Hi, we managed to read a string on variables from the FarDriver's 'blue wire', identified as LIN line. See attached. They pass info to a display, for example the last variable in the line is responsive to 'P' park function. Does anyone have any experience/information about this? We're trying to...

Just one last addition to this thread, an explanation of the LIN communication protocol here - LIN Bus Explained - A Simple Intro [2023] I'm advised that this is better than CAN to implement if you wish to use Fardriver to send info to a display.

Re the ignition switch wire, probably the keyswitch is closing two lines in case you want to switch 2 circuits. You can check easily with a beep test.

Searching for 'DKD ONE-LIN' finds displays that will communicate extensively with Fardriver (and Votol). Here is an example: https://www.aliexpress.com/item/1005004419824878.html?html=static&gatewayAdapt=Msite2Pc It's pulling speed, SoC, gear1-2-3, faults with throttle and controller and power...

Thanks for your quick reply. I sent off requests to Fardriver and the display maker to ask for details. Like you say, it's 50-50 on the usefulness of what will come back. If it's good though, I'll share here. The functionality of displaying FD's info and perhaps via touchscreen switching mode...

Hi, been using Fardriver controller for a couple of years and am familiar with the output of the speed via analog/digital lines. But last week I discovered a display that is also reading the state of the battery and the ride mode (hi, mid, low) from the Fardriver's digital line. Has anyone any...

Thanks for the time to advise.

Hi, they are 3.65V Li-ion NMC cells, commonly available on Aliexpress or Alibaba. I bought from Aliexpress store Deligreen and they offer many sizes depending on your needs. I stick them together with industrial double sided tape, which holds them fast together but is spongy to allow for some...

Thanks for the feedback. I'm charging each cell up from 2V to 3V @1A (they are 92Ah cells). The first one got there in 30 mins so 6 hours for 20S. I'm interested to see how they perform afterwards. They haven't been used much.

Hi, I have a prismatic NCM pack of 20S 92Ah 3.65V nominal cells in an electric motorbike. They have a Daly BMS set to protect them from over discharge, but somehow it didn't do that and whilst stood through winter they have run down to a range 1.8V to 2.2V. Since it's like $900 worth of cells...

Also firmware 11_221122_001T that came with a recent order of 5 x 150A 20S BMS is faulty and turns off the discharge switch when ampage drawn is over 30A. These BMS are very unreliable. My advice is to try another brand.
